The 2020–2022 Malaysian political crisis was triggered after several Members of Parliament (MPs) of the 14th Malaysian Parliament changed party support, leading to the loss of a parliamentary majority, the collapse of two successive coalition governments, and the resignation of two Prime Ministers. The political crisis culminated in a 2022 snap general election and eventual formation of a coalition government. The crisis ended in 2022 at the federal level but continued until 2023 in the state of Sabah in what became known as the Kinabalu Move.
In February 2020, a development commonly dubbed the Sheraton Move, saw the fall of the ruling Pakatan Harapan (PH) coalition government and the resignation of Prime Minister Mahathir Mohamad after 22 months in power. They were replaced by Perikatan Nasional (PN) coalition government led by Prime Minister Muhyiddin Yassin. Political instability continued after these changes throughout 2020 and into 2021, exacerbated by the COVID-19 pandemic. This culminated with the resignation of Muhyiddin and his cabinet in August 2021, after 17 months in power. A few days later, Ismail Sabri Yaakob was appointed the ninth prime minister to replace Muhyiddin. The crisis triggered several early state elections and a 2022 snap general election.
The crisis started with division in the ruling Pakatan Harapan coalition. Some sources suggest this began due to Prime Minister Mahathir Mohamad attempting to thwart the process of handing over power to his designated successor Anwar Ibrahim, as was promised ahead of his 2018 general election victory. Several MPs began discussing forming a new government by claiming majority seats and support in the Dewan Rakyat, the lower chamber of the bicameral Parliament of Malaysia, without going through a general election.
They accomplished it through the withdrawal of the Parti Pribumi BERSATU Malaysia (BERSATU) from the Pakatan Harapan coalition and through the support of several MPs from the Parti Keadilan Rakyat (PKR) led by its deputy president Azmin Ali, who left the party. Prime Minister Mahathir then resigned, creating a power vacuum.
Malaysia's monarch, the Yang di-Pertuan Agong Abdullah of Pahang, then met with all MPs and political party leaders to gauge their support for a new prime minister. He ultimately appointed the president of BERSATU, Muhyiddin Yassin, as the eighth prime minister. Muhyiddin then declared his coalition government as Perikatan Nasional.
Four states – Johor, Malacca, Perak and Kedah – also experienced changes in the respective state governments as Perikatan Nasional gained majorities in the separate state legislative assemblies. The Sabah State Legislative Assembly was dissolved, triggering the 2020 Sabah state election. Perikatan Nasional won the election and formed the state government with Barisan Nasional and United Sabah Party under the Gabungan Rakyat Sabah (GRS) coalition.
Political instability continued after the change in government. Opposition leader Anwar Ibrahim announced he had obtained majority support to form a new government in September 2020, but this did not materialise. Malaysia declared a State of Emergency in January 2021 amid the worsening COVID-19 pandemic, which destabilised the Perikatan Nasional coalition in mid-2021. After a lengthy suspension, parliament temporarily reconvened but expected debates over the emergency measures were blocked, and was then suspended again when COVID-19 cases were detected in the building. Opposition MPs attempted to enter parliament on 2 August 2021 after the State of Emergency was lifted, but were blocked by police. After losing majority support and attempts to regain it were unsuccessful, Prime Minister Muhyiddin and his cabinet resigned on 16 August 2021.
Four days later, UMNO's Vice President Ismail Sabri Yaakob was appointed prime minister by the Yang di-Pertuan Agong after receiving support from the most MPs. Ismail Sabri's government signed a Memorandum of Understanding (MOU) with Pakatan Harapan in an attempt for greater political stability. In 2021 and 2022, instability in state legislative assemblies triggered further elections in Malacca and Johor. The crisis culminated in an early general election in 2022 which produced a hung parliament; Anwar Ibrahim was eventually appointed as prime minister to lead a coalition government.

## Background and key people

Pakatan Harapan (PH) initially was a coalition of four political parties, consisting of Parti Keadilan Rakyat (PKR), Parti Pribumi BERSATU Malaysia (BERSATU), Parti Amanah Negara (AMANAH), and Democratic Action Party (DAP). Established in 2015, the coalition won the 2018 general election when it defeated the ruling Barisan Nasional (BN) coalition government. BN held power in the federal government for almost 60 years, making this the first transfer of power at the federal level to a different political party since Malaysia gained independence. Mahathir Mohamad, then chairman of BERSATU and president of Pakatan Harapan, was elected as the seventh Prime Minister of Malaysia, making him the world's oldest prime minister at age 92. He had previously served as the fourth prime minister from 1981 until 2003 under the United Malays National Organisation (UMNO), a component party of Barisan Nasional. He left the party in 2016 and founded BERSATU to oppose the sixth prime minister, Najib Razak, whom he had repeatedly urged to resign after the 1MDB scandal.
Mahathir reconciled with his former political rival Anwar Ibrahim, the leader of PKR, to win the 2018 election. Anwar was previously Mahathir's deputy prime minister from 1993 to 1998 before he was dismissed and imprisoned from 1998 until 2004 under corruption charges. He was then imprisoned again in 2014 under sodomy charges before receiving a royal pardon in 2018 from the 15th Yang di-Pertuan Agong, Muhammad V of Kelantan. Mahathir had promised to hand over the position of the prime minister to Anwar in two years.
Azmin Ali was the deputy president of PKR and previously served as Anwar's private secretary from 1993 to 1998. He was introduced to Anwar by Mahathir and was regarded as the latter's adopted son. He left Mahathir's UMNO in favour of Anwar's PKR (then called Parti Keadilan Nasional), becoming one of its founding members, after Anwar's first imprisonment. He was appointed by the Sultan of Selangor, Sharafuddin of Selangor over Anwar's wife, Wan Azizah Ismail, as Menteri Besar of Selangor during a highly controversial political manoeuvre dubbed the Kajang Move in 2014. After the 2018 general election, he reconciled with Mahathir, relinquishing his position as Menteri Besar to join Mahathir's cabinet as the Minister of Economic Affairs. Azmin's relationship with Anwar had since turned sour, with Azmin being accused of blocking Anwar from the prime ministerial position. It culminated at PKR's annual national congress in December 2019 where Anwar made vague remarks about treachery in his policy speech, which was believed to have been aimed at Azmin.
Muhyiddin Yassin is the president and a founding member of BERSATU. He was the deputy president of UMNO and had formerly served as the deputy prime minister from 2009 until 2015 under the sixth prime minister, Najib Razak. He was dropped from his position after criticising Najib for his alleged involvement in the 1MDB scandal and was ultimately expelled from the party in 2016. He returned to the cabinet after the 2018 general election and became the Minister of Home Affairs.
Ismail Sabri Yaakob is a senior politician in United Malays National Organisation, part of the Barisan Nasional coalition that had governed Malaysia from its independence until their 2018 election loss. He had served as Leader of the Opposition after BN lost the 2018 election.
Ahmad Zahid Hamidi is the 8th president of United Malays National Organisation since 2018, part of the Barisan Nasional coalition that had governed Malaysia from its independence until their 2018 election loss. He had served as the 11th Deputy Prime Minister to Najib Razak from 2015 to 2018 after Muhyiddin Yassin was fired and expelled from UMNO.
The Yang di-Pertuan Agong, also sometimes referred to as the King of Malaysia, is Malaysia's constitutional monarch. Its position is rotated between the nine Malay rulers every five years. He has the prerogative to appoint the prime minister based on who he believes holds the majority support from the parliament members, under Article 43 of the Malaysia's Constitution. The current and 17th Yang di-Pertuan Agong is Sultan Ibrahim ibni Almarhum Sultan Iskandar who ascended the throne in October 2023.

### COVID-19 pandemic

The global COVID-19 pandemic spread to Malaysia in late January 2020. The first major local outbreak occurred at a Tablighi Jamaat religious event in Kuala Lumpur in late February 2020. As the pandemic emerged as a global crisis by March 2020, including in Malaysia, it has had major economic, social and political impacts.

## 2020
### February: Sheraton Move, fall of Pakatan Harapan government
#### 21-22 February

The presidential council of Pakatan Harapan held a late-night meeting to discuss handing over power from Mahathir Mohamad to Anwar Ibrahim, who was coined as the "Prime Minister-in-waiting" as promised in the 2018 election. It was reported that Anwar conceded to Mahathir to allow the latter to choose a date to resign as the prime minister after APEC Malaysia 2020 in November. However, reports suggested that the meeting was tense and heated during the discussion about Mahathir's departure date. Later in May, a leaked audiotape of the meeting revealed BERSATU Youth chief Syed Saddiq Syed Abdul Rahman and PKR deputy president Azmin both warned Mahathir that he would be a "lame-duck prime minister" if he agreed to a timeline. Anwar's supporters from PKR believed that he should become prime minister based on the originally promised deadline of two years within Pakatan Harapan's election win on 9 May 2020.
Meanwhile, Reuters reported that Mahathir had planned to block Anwar from becoming prime minister, with the plan to be carried out after APEC. Mahathir had begun accepting defectors from UMNO into his BERSATU party and started courting support of opposition parties like PAS with the intention of forming a unity government that would free him from his promise of handing over power to Anwar. However, Anwar's supporters' demand for Mahathir to pick a date for the handing over resulted in the latter's allies to move up their plan, which was carried out on 23 February.

#### 23 February

On 23 February 2020, several political parties held extraordinary meetings: BERSATU at its headquarters at Menara Yayasan Selangor in Petaling Jaya, Muafakat Nasional pact of UMNO and Parti Islam Se-Malaysia (PAS) had a retreat in Janda Baik, Pahang, UMNO's supreme council at Putra World Trade Centre (PWTC), and Gabungan Parti Sarawak (GPS)'s members of the parliament (MPs) in Kuala Lumpur.
Azmin Ali, the deputy president of PKR and the Minister of Economic Affairs, also held a meeting with several lawmakers from the party and twenty others at Sheraton Hotel in Petaling Jaya, amidst rumours that the formation of a new governing coalition was being undertaken. The event was widely reported on local media as Langkah Sheraton or the Sheraton Move.
Azmin and his faction in PKR went to the Istana Negara in the evening to seek an audience with the Yang di-Pertuan Agong. Leaders from five other political parties; BERSATU's Muhyiddin Yassin, also the Minister of Home Affairs, UMNO's Ahmad Zahid Hamidi, PAS's Hadi Awang, GPS's Abang Johari Openg and Parti Warisan Sabah (Warisan)'s Shafie Apdal were also in attendance. It was speculated that the leaders were there to brief the Agong about the recent political development; the formation of a new coalition government and to declare their support for a new prime minister, effectively blocking PKR's president Anwar Ibrahim from the position. After the meeting, several opposition party leaders, including UMNO's Ismail Sabri Yaakob and PAS's Hadi Awang, joined Azmin's supporters at Sheraton Hotel.
In a Facebook Live broadcast of a night prayer session at Anwar's residence, Anwar said that someone had informed him that a "treachery" was committed involving "former friends from BERSATU and a small group from PKR". Later, Azmin, in a statement, claimed that his action was to protect Mahathir, who was forced to choose a date for the transition of power during Pakatan Harapan presidential meeting on 21 February. The statutory declaration (SD) presented to the Agong was to cement support for Mahathir, not to elect a new prime minister. He further said that the real traitor was the faction that tried to usurp Mahathir.

#### 24 February

In the morning of 24 February 2020, Anwar Ibrahim; the deputy prime minister, Wan Azizah Ismail, also Anwar's wife; the president of Amanah, Mat Sabu; and the secretary general of DAP, Lim Guan Eng, met Mahathir at his residence to seek clarification regarding the incident. Anwar later stated that he was satisfied with the meeting outcome, as Mahathir had clarified that he had nothing to do with the pact to make a new coalition government.
PKR held a press conference at 2 pm where its general secretary, Saifuddin Nasution Ismail, announced that Azmin and the Minister of Housing and Local Government, Zuraida Kamaruddin, also the vice president of PKR, had been dismissed by the party. Saifuddin explained that they were expelled due to their actions on 23 February which was against the party's principle regarding the position of prime minister. Azmin later announced that he would be forming an independent bloc at the parliament along with Zuraida and other nine MPs. They had decided to exit the party following his expulsion.
In the afternoon of 24 February, the prime minister's office confirmed that Mahathir had submitted his resignation to the Agong. Half an hour later, he also announced his resignation from his position as chairman of BERSATU after Muhyiddin declared the party's withdrawal from Pakatan Harapan coalition. The Agong tried to convince Mahathir against resigning, but the latter insisted. The Agong then accepted his resignation and appointed him as the interim prime minister until a new prime minister is chosen. The Cabinet of Malaysia was dissolved, per Article 43(5) of the Constitution of Malaysia. Pakatan Harapan lost its majority in the parliament after BERSATU and Azmin Ali's-led PKR faction of eleven MPs withdrew from the coalition at 2 pm. A representative of the palace then announced that the Agong would interview all 221 MPs, excluding Mahathir, to weigh their support for prime minister candidates. The interview sessions were held on 25 and 26 February, with 90 MPs on the former and 131 MPs on the latter.
At 9 pm, BERSATU leaders held an emergency meeting at its headquarters to discuss the party's future direction. Members of BERSATU rejected Mahathir's resignation as the party's chairman and pledged their support for him to be the prime minister. The party's secretary-general Marzuki Yahya said that the BERSATU's supreme council members were unanimous in their support for Mahathir.

#### 25 February

On 25 February, Agong summoned 90 MPs to have an audience with the Yang di-Pertuan Agong. Starting from 2:30 pm, the Agong spent two to three minutes interviewing each MPs. Following the first round of interviews, UMNO and PAS revealed that they have withdrawn their earlier support for Mahathir to remain as prime minister, and had instead called for parliament dissolution. It was previously reported that as all political factions voiced their support for Mahathir, he was about to establish a "unity government" that the two parties did not agree with. Annuar Musa, UMNO's secretary-general, said the basis of negotiations with Mahathir was that UMNO and PAS would lend their support to form an alternative coalition without DAP. Therefore, both PAS and UMNO declared their support for a snap election instead.
An emergency Pakatan Harapan presidential council meeting was held at PKR's headquarters in Petaling Jaya at night. Pakatan Harapan parties; DAP, PKR and Amanah invited Mahathir to the meeting in order to restore the previous government but Mahathir did not attend the joint meeting.
Later on 3 February 2021, Mahathir claimed that when the Pakatan Harapan MPs made their statutory declaration in front of the Agong, they did not name him as their candidate. Anwar had convinced PH MPs that he had sufficient support from Sabah and Sarawak MPs and PH MPs to have a majority to become prime minister. Mahathir said that "only DAP, Amanah, and his faction of his PKR" supported Anwar. Anwar had 92 supporters while Mahathir had 62. "When Muhyiddin was named Prime Minister he did not have majority support. But upon his appointment he was able to offer places in his cabinet to the members who supported me. They crossed over and Muhyiddin achieved a majority of two", Mahathir wrote on his blog.

#### 26 February

Interim Prime Minister Mahathir addressed the nation at 4.45 pm on the political situation. He began his speech by apologising to Malaysians for the current impasse before confirming speculation that he wanted to form a unity government, saying the new administration would focus on national interests instead of political parties. Mahathir denied allegations of being obsessed with power, and reiterated his refusal to work with UMNO. Mahathir made no mention of Anwar Ibrahim or the agreement to pass the leadership baton to Anwar as agreed during 21 February meeting. Mahathir instead said the decision was up to the Dewan Rakyat.
Pakatan Harapan announced that they were nominating PKR president Anwar Ibrahim as prime minister following the previous night's meeting, despite publicly declaring support for Mahathir earlier, following Mahathir's televised speech. DAP lawmakers said Pakatan Harapan decided against a non-partisan "Mahathir government" as this would not be beholden to any party or coalition, which would give Mahathir free rein to do as he wanted.

#### 27 February

In the morning of 27 February, Mahathir once again went to the palace for an audience with the Agong. The contents of this meeting remain unknown, although it was alleged to have been a discussion on the formation of a new cabinet. In the afternoon, the secretary general of BERSATU, Marzuki Yahya, confirmed that Mahathir had withdrawn his resignation as the chairman of BERSATU. In an unrelated press conference on the evening of 27 February, Mahathir revealed that the Agong "[could not] find anyone with a distinct majority" to be elected as the prime minister and that a special session of parliament would be held on 2 March to address the predicament. If all else failed, he hinted that there would be a snap election.

#### 28 February

A special Conference of Rulers meeting was held on the morning of 28 February at the Istana Negara to discuss the current political climate in the country, with all state rulers or their crown princes in attendance. They were also joined by General Affendi Buang, the Chief of Defence Forces, and Abdul Hamid Bador, the Inspector-General of Police.
Mohamad Ariff Md Yusof, the speaker of the Dewan Rakyat, contradicted Mahathir's previous announcement regarding the special sitting of the parliament. Ariff said that he had received a letter from Mahathir stating that the government agreed for a sitting to be called on 2 March but it did not adhere to parliamentary Standing Orders. In the evening, the palace released a statement saying that the Yang di-Pertuan Agong would call the leaders of political parties who have members in the parliament for an audience, to allow them to nominate their candidates for the position of prime minister to break the impasse. It also confirmed that the Agong had not found a candidate who had the confidence of the majority of the MPs to form a new government.
BERSATU then released a statement announcing their support for the party's president, Muhyiddin Yassin as the 8th Prime Minister, backed by the 26 BERSATU MPs and 10 others led by Azmin. Further 60 MPs from UMNO, PAS, Malaysian Chinese Association (MCA) and Malaysian Indian Congress (MIC) also announced their support for Muhyiddin. All the Muafakat Nasional MPs had also signed the new statutory declarations proposing Muhyiddin to be the next prime minister. Muhyiddin Yassin's aide also confirmed that Azmin Ali and 10 other former PKR MPs have officially joined BERSATU. However, BERSATU Supreme Council member Kadir Jasin claimed he was never invited for a discussion or informed about Muhyiddin's nomination.

#### 29 February

BERSATU Youth chief Syed Saddiq Syed Abdul Rahman declared that he would never work with those involved in corruption to form a government, referring to UMNO. BERSATU's youth wing Armada also posted a statement to say that it would continue to back the party's supreme council's decision in its meeting on 24 February to support Mahathir as prime minister, suggesting a split within BERSATU over Mahathir and Muhyiddin's candidacy.
In the morning of 29 February, the Pakatan Harapan presidential council held a meeting to discuss the political situation. They then announced their full support for Mahathir as the 8th Prime Minister, thus reversing the coalition's nomination of PKR president Anwar Ibrahim for prime minister. Following the announcement, Mahathir expressed confidence that he had the majority support to form the government and could be appointed as the prime minister for the third time after receiving assent from the Yang di-Pertuan Agong. In the afternoon, Anwar, as a representative of Pakatan Harapan went to Istana Negara to inform the Agong of the nomination changes.
Meanwhile, BERSATU's Muhyiddin Yassin and his allies including party leaders from UMNO, PAS, Gabungan Parti Sarawak (GPS), Parti Bersatu Rakyat Sabah (PBRS), and Homeland Solidarity Party (STAR) had an audience with the Agong. He also announced that his coalition consisting of BERSATU, UMNO, PAS, PBRS, GPS, and STAR would be called Perikatan Nasional. The new coalition claimed that they had majority support in parliament to elect a prime minister and to form a government.
Meanwhile, in Sarawak, Chong Chieng Jen who is vice-chairperson of DAP as well as chairman of DAP Sarawak, said they were willing to make concessions and work together with the GPS state government. The main purpose for this was to preserve the PH federal government. Chief Minister, Abang Abdul Rahman Johari Abang Openg snubbed Chong's peace gestures to the state coalition, recalling past remarks by DAP secretary-general Lim Guan Eng, that Sarawak would go bankrupt in the next three years. PKR announced that GPS MP Richard Riot Jaem had defected to join the party. However, he denied the allegation, stating that he was still a member of the GPS component party, Sarawak United Peoples' Party (SUPP), and had merely voiced out his support for Mahathir.
In the evening, the royal palace released a statement announcing that Muhyiddin, in the Yang di-Pertuan Agong's judgment, is likely to command the confidence of the majority of the MPs and was to be appointed as the 8th Prime Minister of Malaysia. The swearing-in ceremony would be held in the morning of 1 March in the Istana Negara.
Late that night, Mahathir, in a final attempt to challenge Muhyiddin's appointment, published a list of 115 Members of Parliament whom he claimed was supported him and enclosed the list with a letter to be delivered to the Agong following a Pakatan Harapan meeting. Notable MPs who were in the list are Mahathir, his son Mukhriz Mahathir and 4 other BERSATU MPs, members of Warisan, Jeffrey Kitingan of STAR, Maximus Ongkili of Gabungan BERSATU Sabah (GBS), Baru Bian and Jonathan Yasin who were previously in Azmin's bloc. However, the list was disputable as some MPs had denied backing Mahathir and some were ambiguous about their allegiance. Shamrahayu Abd Aziz, an academic and an expert on the constitution stated that any statutory declaration signed after the Agong's announcement would not make a difference, and the legal way to challenge Muhyiddin's appointment was through a vote of non-confidence in the Dewan Rakyat.

### March: New prime minister, Perikatan Nasional inception, coronavirus pandemic

Minutes before the swearing ceremony of Muhyiddin, Mahathir said in a press conference that the Istana Negara had refused to grant him an audience to prove that Pakatan Harapan commanded the support of the majority of the Dewan Rakyat. He expressed disappointment towards Muhyiddin, who he alleged had been working on forming a government without Pakatan Harapan "for a long time". Mahathir also revealed that the confusion over the status of his chairmanship of BERSATU allowed Muhyiddin to appoint himself as the chairman, which he claimed was an illegal move.
Muhyiddin Yassin was sworn in as the eighth prime minister in front of the Agong at the Istana Negara on the morning of 1 March 2020.
On the morning of 2 March, Muhyiddin arrived at the Perdana Putra, to begin his official duties as the prime minister. Muhyiddin held meetings with Chief Secretary Mohd Zuki Ali, General Affendi Buang, the Chief of Defence Forces, and Abdul Hamid Bador, the Inspector-General of Police. Later that night, Muhyiddin addressed the nation in his first televised message as the prime minister. In his address, he told the nation that he had no prior intention to become the prime minister and denied being a traitor but due to the political turmoil in the country, he stepped up in order to avoid prolonging the crisis further. He also reassured that he will only choose individuals who are clean, virtuous and of high calibre to be in his cabinet. Before ending his message, he thanked former prime minister Mahathir for his service to the country.
Within weeks of Muhyiddin becoming prime minister, the COVID-19 pandemic emerged as a serious crisis both in the country and globally. A Tablighi Jamaat religious event in Kuala Lumpur that took place during the political crisis had been a superspreading event, where the outbreak rapidly spread across the country. The political instability at the time was thought to have hampered the country's ability to respond. Muhyiddin announced that international borders would close and announced a strict Movement Control Order, putting the country into lockdown from 18 March.
On 4 March, the Speaker of the Dewan Rakyat, Mohamad Ariff Md Yusof announced that the Dewan Rakyat sitting which was originally scheduled to start on 9 March would be postponed to 18 May at the direction of Muhyiddin. The action was taken to allow the new prime minister to form his cabinet and for the newly appointed ministers to familiarise themselves with their ministry before the parliament sitting. However, PKR MP Wong Chen criticised Muhyiddin's move in delaying the opening of parliament, saying that it [was] a clear sign of weakness as he [was] unable to form a cabinet in a swift manner.
Muhyiddin on 10 March announced a Perikatan Nasional (PN) cabinet that he had picked from a mix of seasoned politicians, technocrats, stalwarts and close allies as ministers. However, this cabinet excluded the deputy prime minister position, which was instead replaced with 4 senior ministers for the first time.

### May–July: Parliamentary sittings

In a Facebook Live session on 7 May, Anwar Ibrahim announced that he would be the new Leader of the Opposition for Pakatan Harapan in the new session of Parliament.
Speaker Mohamad Ariff announced on 7 May that he had received a letter on 1 May from Warisan leader Shafie Apdal seeking to table a motion of confidence in Dr Mahathir to show that he could command a majority in the Dewan Rakyat. The Speaker replied in a letter to Shafie that it was not in line with Article 43 of the Federal Constitution because it questioned the power of the Yang di-Pertuan Agong to appoint the prime minister. Mahathir sought a motion of no confidence against Muhyiddin as prime minister through a letter addressed to Ariff on 4 May. On 8 May, the Speaker accepted Dr Mahathir's motion and it would be debated when Parliament resumed on 18 May.
The speaker announced on 13 May that on the directions of the government, the parliament sitting on 18 May would only convene for the opening speech by the Agong initiating the new session, with no meeting after the speech. This meant that Mahathir's no confidence motion would not be debated as initially planned. Secretary to the Dewan Rakyat, Riduan Rahmat who was appointed on 22 February two days before the Sheraton Move, was demoted to Dewan Negara management secretary on 14 May. A source alleged that the secretary had attempted to keep the motion of no-confidence against Muhyiddin by Mahathir and Shafie a secret, leading to his demotion. In response, both Mahathir and Shafie along with Pakatan Harapan leaders condemned the move in a joint statement and accused the Perikatan Nasional government of being afraid to face the opposition in parliament.
The Agong addressed the political crisis by recounting that he tried to convince then-PM Mahathir not to resign but had no choice but to accept it as the latter insisted on resigning. The Agong ended his speech by calling on politicians not to drag the country into any further political crisis when there was already a COVID-19 pandemic crisis. The new seating arrangement in the Dewan Rakyat suggested that the Perikatan government had 113 seats in the Dewan Rakyat, after Masir Kujat of Parti Sarawak BERSATU (PSB) clarified that he was not supporting the government, and remained as opposition in federal and state levels. In a press conference attended by Mahathir, Shafie Apdal, Mukhriz Mahathir, Lim Guan Eng and Mat Sabu following the parliamentary seating, Mahathir insisted that BERSATU was still a component of Pakatan Harapan as its Supreme Council never decided to exit the coalition. In a leaked audio tape of the supreme council meeting in February, Muhyiddin had allegedly given Mahathir a week to decide on the party's direction as its chairman. "But before the one-week period, he took action as if he was not in PH. This goes against the party constitution and (any) approval by BERSATU (sic) Supreme Council," said Mahathir. Notably, neither Anwar nor any representatives of PKR attended the press conference.
Mahathir Mohamad, Mukhriz Mahathir, Syed Saddiq Syed Abdul Rahman, Maszlee Malik and Amiruddin Hamzah were expelled from BERSATU on 28 May. They decried the move as illegal and reflective of Muhyiddin's insecurities and dictatorial leadership. In a joint statement, they disputed the interpretation of their decision not to join Muhyiddin's government benches in Parliament as joining another party, which resulted in an automatic revocation of membership, according to the BERSATU party constitution. However, Muhyiddin defended the move and insisted that the five members who were sacked as having breached the party constitution by sitting with the opposition in Parliament.
Speaker Mohamad Ariff was removed from his position on the next parliamentary sitting on 13 July by a margin of two votes, 111 to 109 and was controversially replaced by recently resigned Electoral Commission (EC) chairman, Azhar Azizan Harun as the new speaker. Azhar's appointment took place amidst a shouting match between Pakatan Harapan and Perikatan Nasional MPs, after he was sworn in without a voting session by lawmakers, similar to the removal the incumbent Speaker. However, in his press conference with the media later, Azhar insisted that his appointment was legitimate, saying that there was no need for a voting session in the Lower House, as there was only one nominee. The Deputy Speaker, Nga Kor Ming announced his resignation in solidarity with Speaker Ariff. With the resignation of Nga, Prime Minister Muhyiddin announced Azalina Othman Said would replace Nga, making her the first female Deputy Speaker.

### September–December: Elections in Sabah, Anwar Ibrahim's bid for premiership

On 23 September, at an afternoon press conference, Anwar Ibrahim, Leader of the Opposition, Pakatan Harapan (PH) coalition and People's Justice Party (PKR), announced and claimed that he had commanded a "strong, formidable, convincing majority" and further claimed that the Perikatan Nasional (PN) federal administration led by Prime Minister Muhyiddin Yassin "has fallen". However, Anwar also revealed that his planned audience with the Agong earlier on 22 September had been postponed due to the hospitalisation of the Agong to receive treatment for food poisoning and a sports injury at the National Heart Institute (IJN) on 21 September. When Anwar Ibrahim met the Agong on 13 October, he presented the number of 120 MPs to the Agong but did not submit the names of all the MPs supporting him.
The Sabah state election took place on 26 September, which led to a Perikatan Nasional victory. After calls to allow postal voting or stop the election were dismissed over concerns on the spread of COVID-19, the vote was held in-person with certain Standard Operating Procedures (SOPs). The election led to a major COVID-19 outbreak in Sabah which later spread to other states across the country.
By-elections in the Bugaya constituency in Sabah and the Gerik constituency in Perak were both suspended at the request of Prime Minister Muhyiddin in December 2020 by invoking states of emergency over rising COVID-19 cases. Bugaya was thought to be the epicentre of the third wave of COVID-19 in Sabah. Muhyiddin had requested a nationwide state of emergency, but this was rejected by the Agong.

## 2021
### January: Minority government, emergency declaration

On 13 December 2020, UMNO veteran Tengku Razaleigh Hamzah held a joint press conference with his longtime rival Mahathir Mohamad, where he publicly declared his rejection of the 2021 budget tabled by Muhyiddin. Both men also declared the PN government illegitimate. Razaleigh did not attend the subsequent budget vote held on 14 December, which was won by the government with 111 ayes against 108 nays.
With growing dissatisfaction within the party ranks over a number of issues, MPs from UMNO began to publicly call for withdrawal from the PN coalition government. Minister of Federal Territories Annuar Musa, who was firm in his stance of "no Anwar, no DAP" with regards to political cooperation, was sacked on 5 January 2021 as Barisan Nasional Secretary General. Annuar's successor Ahmad Maslan publicly called for a general election and labeled ongoing court cases against leading UMNO figures as "cruel". Annuar himself later alleged in a press conference that a number of UMNO MPs backed by UMNO President Ahmad Zahid Hamidi were planning on leaving Perikatan Nasional to form a coalition government with DAP and possibly other PH component parties. The statement was denied by both former Prime Minister Najib Razak and DAP Secretary-General Lim Guan Eng.
Machang MP Ahmad Jazlan Yaakub held a press conference to personally and publicly announce his withdrawal of support for the PN government and resignation as Chairman of the Malaysian Palm Oil Board (MPOB). Jazlan cited BERSATU's repeated attempts to "bully" UMNO as the primary reason for withdrawing support. This resulted in a further collapse of the PN administration led by Prime Minister Muhyiddin Yassin, at this point commanding the support of only 110 out of 220 MPs in the Dewan Rakyat, Parliament.
On 12 January, the Yang di-Pertuan Agong consented to a national emergency proclamation under Article 150 of the Malaysian Constitution to contain the COVID-19 pandemic, effective from 12 January 2021 to 1 August 2021. With the proclamation, parliament was officially suspended and no snap elections could be held. Mohamed Nazri Abdul Aziz held a press conference on the same day to publicly and personally announce his withdrawal of support, declaring he was no longer aligned with PN as an MP, although his coalition was, further reducing Muhyiddin Yassin's majority to only 109 out of 220 MPs. His withdrawal of support is the third one from his coalition after the withdrawals of support of Tengku Razaleigh Hamzah (Gua Musang MP) and Ahmad Jazlan Yaakub (Machang MP). Nazri told the press that the proclamation was only further evidence that Muhyiddin was unable to prove he commands majority support in parliament if a confidence motion was held.
On 18 January, Khairuddin Abu Hassan sued Muhyiddin and his administration over the latter's announcement of a nationwide state of emergency. Khairuddin believed that what Muhyiddin was unlawful and unconstitutional, since Muhyiddin had already lost the majority needed to hold government.
On 23 January, opposition leader Anwar Ibrahim said 115 MPs were against the proclamation of the emergency. Media reports had previously claimed that many MPs had submitted an appeal letter to the King to end the state of emergency imposed on 13 January to fight COVID-19. The opposition claimed the prime minister's move was only to hold on to power, with Parliament suspended.

### February–July: Royal consent for parliament, more crossovers

On 24 February, King Abdullah consented for parliament to reconvene during the emergency period after an audience with President of the Dewan Negara Rais Yatim and Speaker of the Dewan Rakyat Azhar Azizan Harun, but left it to the Prime Minister to set a date.
On 28 February, rumours were rife that two Pakatan Harapan (PH) and People's Justice Party (PKR) MPs, Tebrau MP Steven Choong and Julau MP Larry Sng would become independents and declare support for the ruling Perikatan Nasional (PN) coalition to provide it with a majority in the Dewan Rakyat, where it only had the support of 109 MPs out of 111 needed for a majority. In the afternoon on the same day, Julau MP Larry Sng confirmed the rumours and signed statutory declarations (SDs) in support of PN with Choong, handing them to Prime Minister Muhyiddin. PN thus regained majority support after the withdrawals of three BN MPs in January, whereas the opposition was once again reduce to a minority in the Dewan Rakyat.
On 4 March, UMNO announced its support for PN only remained until the dissolution of Parliament, whereby it would withdraw its support after.
On 13 March, PH and PKR Kuala Langat MP and vice-president of PKR Xavier Jayakumar Arulanandam announced his departure from PKR and resignation as PKR Vice-president, crossing over to support the PN led by Muhyiddin Yassin, becoming the third Opposition MP to do so in less than a month after Larry and Steven, as well as strengthening the majority support of PN in the Dewan Rakyat, PN had the support of 112 MPs following his crossover. Parliament carried on being closed after the government decided not to reconvene due to the COVID-19 pandemic. However, the reason was not accepted by the Opposition, leading them to form a Committee for Ending the Emergency Declaration and to launch a petition to appeal for an end to the state of emergency.
On 4 June, Minister in the Prime Minister's Department (Parliament and Law) Takiyuddin Hassan announced that the government was studying ways to reconvene Parliament by holding hybrid sessions virtually and physically to divide the MPs into two groups to attend virtual and physical sessions.
On 7 June, a loyalist of former Prime Minister Mahathir, who strongly opposed the Muhyiddin government, Khairuddin Abu Hassan revealed that the Agong had invited the heads of the major political parties to listen to their views on the current issues ranging from politics, the economy, the COVID-19 pandemic from 9 to 15 June 2021. The invitees included the Prime Minister, Chairman of PN, President of BERSATU Muhyiddin Yassin, Leader of the Opposition, Chairman of PH and President of PKR Anwar Ibrahim, Deputy Chairman of PH, Secretary-General of DAP Lim Guan Eng, former prime minister and Chairman of PEJUANG Mahathir Mohamad, Special Envoy of the Prime Minister to Middle East and President of PAS Abdul Hadi Awang, and former deputy prime minister, Chairman of BN and President of UMNO Ahmad Zahid Hamidi.
On 15 June, Prime Minister Muhyiddin announced that Parliament might be reconvened in September or October 2021 during the third phase of the National Recovery Plan through a televised address. On 16 June 2021, King Abdullah held a special meeting of the Conference of Rulers (COR) at Istana Negara involving rulers of nine states to discuss the views of the invitees of the audiences and issued a statement that the COR agreed that Parliament should be reconvened as soon as possible, and that the Emergency declaration should not be extended and instead be lifted on 1 August 2021. On 20 June 2021, Prime Minister Muhyiddin claimed that a committee consisting of Government and Opposition MPs was formed to look into every aspect of the reconvening of Parliament to avoid any issues. On 21 June 2021, BN Chairman and UMNO President Ahmad Zahid warned the PN government against treason and disrespect towards the royal institution and gave it a 14-day deadline to reconvene Parliament. He also announced that the Supreme Council of UMNO would meet to discuss the next course of action if their requests and warnings were not fulfilled by the deadline.
On 2 July, Mohamed Nazri Abdul Aziz claimed that he has returned to support Prime Minister Muhyiddin and withdrew his withdrawal of support declared on 12 January in the same year. His return of support further strengthened the PN government by increasing its majority in Parliament of 112 MPs to 113 MPs.
On 5 July, on the deadline set by UMNO, the Prime Minister's Office (PMO) announced that the Parliament would finally reconvene with two special sessions of Dewan Rakyat from 26 July to 2 August for five days and of Dewan Negara from 3 to 5 August for three days. The PN government also advised the MPs to seize this opportunity to help the government in containing the COVID-19 pandemic by expressing their views and suggestions. However, on 7 July 2021, Pakatan Harapan (PH) presidential council urged the PN government to extend the five-day special Dewan Rakyat session as it was too short to discuss key issues that have been highlighted by the Yang di-Pertuan Agong and regretted that the PN government only intended to provide an explanation on the National Recovery Plan (NRP) without any debate, while the Emergency proclamation and Emergency Ordinance would only be tabled and not discussed or decided.

### July: Political instability increases

On 7 July, a minor Cabinet reshuffle aimed at distributing more powers and positions to UMNO took place by promoting two UMNO Cabinet members, namely Ismail Sabri Yaakob from Senior Minister (Security) to the 13th Deputy Prime Minister and Hishammuddin Hussein, Minister of Foreign Affairs to Senior Minister (Security). It was seen as a gesture to ease the tensions between UMNO and PN as well as to persuade UMNO, which has been unsatisfied with PN due to the unequal distribution of powers and positions, to retain their support for Muhyiddin as PM and PN as government.
However, on 8 July 2021, after a UMNO supreme council meeting had been held, BN Chairman and UMNO President Ahmad Zahid addressed the media virtually and announced that UMNO would officially withdraw support for PM Muhyiddin with immediate effect. He cited the government's failure to contain the COVID-19 pandemic, dissatisfaction with the economic response and the extension of the Movement Control Order. He also called for the appointment of a new prime minister who would concentrate on containing the COVID-19 pandemic, before the next election immediately after the nation achieves herd immunity against COVID-19 through the vaccination programme. Later that day, the Attorney General of Malaysia Idrus Harun said that Muhyiddin and his Cabinet could still exercise power as there was no clear evidence to show that the team had lost the majority of lawmakers. In addition, BERSATU's information chief Wan Saiful Wan Jan rejected accusations by Ahmad Zahid that the Government failed.
On 10 July, UMNO's vice-president and newly appointed Deputy Prime Minister Ismail Sabri Yaakob said the majority of UMNO's supreme council disagreed with Ahmad Zahid's directive to withdraw support for Muhyiddin at this point amid the current pandemic as it was not a "reasonable move", and that efforts should be focused on helping people during these times instead of politicking. Although UMNO decided earlier in a 2020 meeting to withdraw support for Perikatan Nasional, the decision did not have to be carried out now, saying that this had to be done at the right time. Four days later, the Cabinet including all nine ministers from UMNO agreed to support Muhyiddin as prime minister to lead Malaysia out of the crisis.
Parliament reconvened on 26 July for the first time in 2021, for a special five-day session. The Agong requested that State of Emergency measures be discussed in Parliament; the government stated no other issues were to be debated. The session was chaotic; no debate or vote was held on COVID-19 emergency measures and opposition leader Anwar Ibrahim and former Prime Minister Mahathir accused the government of not fulfilling the Agong's request. Prime Minister Muhyiddin also left early, which incensed the opposition. Delays occurred when positive COVID-19 cases were detected among parliamentarians.
Law Minister Takiyuddin Hassan also told Parliament on 26 July that the State of Emergency had been annulled on 21 July. On 29 July, the Yang di-Pertuan Agong released a rare rebuke criticising the government, and singled out Takiyuddin in particular, accusing him of misleading Parliament on the revocation of the state of emergency which he had not approved. The palace said that the Agong was "amat dukacita" (deeply disappointed), and said Takiyuddin and Attorney-General Idrus Harun did not fulfil their promise to the Yang di-Pertuan Agong to have the State of Emergency debated. Opposition Leader Anwar Ibrahim read the Agong's statement aloud in Parliament, accusing the Muhyiddin cabinet of "violat[ing] the constitution and insult[ing] the royal institution" and filed a no-confidence motion against Muhyiddin. Deputy Speaker Mohd Rashid Hasnon dismissed the Agong's letter as a "media statement". Other opposition lawmakers shouted "treason" and "resign" as Anwar read the Agong's statement.
The special parliamentary session was suspended on 31 July when 11 positive COVID-19 cases were detected among its members. The opposition criticised this, accusing the government of further delaying parliamentary debate.
On 31 July, hundreds of protesters attempted to gather in Merdeka Square, Kuala Lumpur, calling for the resignation of Prime Minister Muhyiddin Yassin over his and the Malaysian government's handling of the COVID-19 pandemic.

### August: Fall of Perikatan Nasional government, new prime minister

After the nationwide State of Emergency ended, a new one was declared in Sarawak starting from 2 August, delaying the Sarawak state election to February 2022 which would have otherwise occurred in 2021.
On 2 August, opposition MPs attempted to enter parliament in defiance of the session's suspension over COVID-19 cases detected in the building, but were blocked by police. They instead gathered in protest at Merdeka Square and called for Prime Minister Muhyiddin to resign. Anwar Ibrahim and Mahathir Mohamad were both in attendance. Anwar had been quoted saying that Muhyiddin's government had lost its majority support and called for its resignation. They had attempted to march to the parliament from Merdeka Square, until they were blocked by the Federal Reserve Unit (FRU), who are usually called to handle riots. Afterwards, the MPs dispersed peacefully, and police indicated that the lawmakers would be summoned for questioning.
On 3 August, the President of UMNO Ahmad Zahid Hamidi along with 10 other UMNO MPs held a press conference announcing the withdrawal of UMNO's support for Muhyiddin as prime minister.
Following the announcement of UMNO's withdrawal, two UMNO cabinet ministers - Minister of Energy and Natural Resources Shamsul Anuar Nasarah and Minister of Higher Education Noraini Ahmad - resigned from their posts on 3 August and 6 August respectively, citing loyalty to the party.
On 4 August, Prime Minister Muhyiddin Yassin and the Perikatan Nasional government held a special address to the nation alongside the Deputy Prime Minister and Vice President of UMNO Ismail Sabri Yaakob, whereby he announced that he would not resign, and that he would table a motion of confidence to establish the legitimacy of his position in the Dewan Rakyat in September. He also added that the Yang di-Pertuan Agong had sent him a letter regarding 8 UMNO lawmakers' request to withdraw support for Muhyiddin, and that Muhyiddin must resign should he lose the majority support in parliament. A few other PN MPs stated that Muhyiddin still possessed a majority in parliament. Pakatan Harapan MPs rejected the claims, maintaining that Muhyiddin and the Cabinet should resign. They also added that the motion should be tabled before 9 August to end the issue of the prime minister's legitimacy. Several parties also emphasised an immediate tabling of the confidence motion.
Following Ismail Sabri's support for Muhyiddin, this started a split in the party as some UMNO MPs continued their support for Muhyiddin while some MPs joined Ahmad Zahid Hamidi in withdrawing their support for Muhyiddin. The support totalled up to 31 Barisan Nasional members.
On 9 August, UMNO's website displayed documents of UMNO president Ahmad Zahid Hamidi, of whom presented a list of 14 UMNO MPs to the Yang di-Pertuan Agong, to inform the King of their signed statutory declarations dated 29 July to 3 August to withdraw support for Prime Minister Muhyiddin Yassin. The list includes the 11 MPs that held the press conference on 3 August, former Minister of Energy and Natural Resources Shamsul Anuar Nasarah, and both Sabah UMNO MPs Bung Moktar Radin and Mohamad Alamin.
By 9 August, 15 UMNO MPs had withdrawn their support for Muhyiddin as prime minister.
| For | Against | Total |
| 23 | 15 | 38 |
On 11 August, top leaders in the ruling Perikatan Nasional coalition flocked to the Perdana Putra Complex to attend a political meeting with Prime Minister Muhyiddin Yassin.
On 12 August, Minister of Communications and Multimedia Saifuddin Abdullah announced that the confidence motion would be held on 7 September. In addition, Johor Sultan Ibrahim Iskandar said he would not hesitate to dissolve the Johor State Legislative Assembly if politicians continued to struggle for power and destabilise the state.
On 13 August in a televised address, Muhyiddin offered a series of major concessions to opposition parties, including opposition leader Anwar, in an attempt to form a unity government ahead of an expected vote of confidence scheduled for September. These included a constitutional amendment to introduce two-term limits for the Prime Minister, equal financial allocation for all MPs, greater resources for the Leader of the Opposition, introducing an anti-party hopping bill in Parliament, balanced parliamentary committees, allowing 18-year-olds to vote, and a general election by July 2022, among others. These were unanimously rejected by all opposition parties, who characterised the proposal as corruption and reiterated calls for Muhyiddin to resign.
On 15 August, Mohd Redzuan Md Yusof, the Minister in the Prime Minister's Department (Special Functions) said that Prime Minister Muhyiddin Yassin would announce his resignation the following day. On August 17, the Muhyiddin cabinet was dissolved after the ministers handed in their resignation to His Majesty the Yang Di-Pertuan Agong, with Muhyiddin remaining as caretaker prime minister until a new leader was appointed. Muhyiddin admitted he had lost majority support in a televised address, and said that he would not "conspire with kleptocrats, or interfere with the judiciary or turn his back on the Constitution to stay in power". The Palace also announced that an election would not be held due to the ongoing pandemic, and that the Agong would once again appoint the next premier.
On 17 August, the Yang di-Pertuan Agong again met with MPs, asking them to send him their choice for next prime minister via fax, email or WhatsApp by 4pm on 18 August. Political leaders met with MPs in an attempt to gain supporters. Local media reported Ismail Sabri Yaakob, Anwar Ibrahim, Tengku Razaleigh Hamzah and Shafie Apdal were in the running. In addition, the Yang di-Pertuan Agong made it clear to parties that a new form of politics that brings peace and harmony was needed, with all parties reaching a consensus towards that.
According to reports the following day, UMNO nominated Ismail Sabri Yaakob as their candidate for prime minister and was supported by PAS and BERSATU, with Anwar Ibrahim nominated by the Pakatan Harapan coalition and supported by its component parties. UMNO initially suggested 3 potential PM candidates — Ahmad Zahid Hamidi, Mohamad Hasan and Ismail Sabri Yaakob. However, Zahid withdrew himself and Mohamad was ineligible as a non-MP. This automatically paved the way for Ismail Sabri. It was also reported that an UMNO MP did not support Sabri, which was revealed to be Tengku Razaleigh Hamzah. Meanwhile, the Yang di-Pertuan Agong called for a meeting two days later with all state rulers and asked that a confidence motion be tabled to confirm the majority.
On 19 August, meetings began with the Yang di-Pertuan Agong to verify support of Members of Parliarment (MP) who nominated Ismail Sabri as a candidate. Istana Negara received nominations for the future prime minister from 220 members of the Dewan Rakyat, each through a statutory declaration on 18 August 2021. From the declaration letters, a total of 114 members of the Dewan Rakyat nominated Ismail Sabri, a sufficient majority to form the government. Following that, the Yang di-Pertuan Agong agreed to grant an audience with the 114 members of the Dewan Rakyat to confirm their trust in Ismail Sabri who was nominated to be appointed as the next prime minister. Subsequently, Perikatan Nasional chairperson Muhyiddin affirmed support for Ismail Sabri provided the Cabinet did not include MPs facing criminal charges. An online petition opposing Ismail Sabri's appointment gained over 200,000 signatures within the first 8 hours, and subsequently garnered more than 350,000 signatures.
On 20 August, the Yang di-Pertuan Agong named UMNO's vice president, Ismail Sabri Yaakob as the nation's 9th Prime Minister in accordance with Article 40(2)(a) and Article 43(2)(a) of the Federal Constitution after being satisfied that he commanded the confidence of the majority in Parliament.
Ismail Sabri was formally appointed and sworn in as the ninth prime minister of Malaysia in front of the Yang di-Pertuan Agong at the Istana Negara on the afternoon of 21 August 2021. Ismail Sabri formed his new cabinet after getting approval from the Yang di-Pertuan Agong following a meeting on 26 August at the Istana Abdulaziz in Pahang, Kuantan. The Prime Minister's Office replied to the media that the cabinet list would be announced at 11am the next day and the swearing-in of all ministers would be done on 30 August 2021. When the new cabinet was announced, it consisted of ministers mostly retained from the Muhyiddin cabinet with some minor changes.
Opposition parties criticised the newly formed cabinet. The leader of the opposition, Anwar Ibrahim described it as a "recycled cabinet" of Muhyiddin's government, and stated that a majority of the people were disappointed with the new cabinet ministers as they had failed to fulfil their previous duties during the PN administration, and that the new cabinet could not bring in confidence among domestic and foreign investors. DAP's secretary-general, Lim Guan Eng questioned the competency of the new cabinet line-up unveiled by the Prime Minister.
Deputy Minister for Education II Mohamad Alamin could not attend the swearing-in ceremony due to being infected with COVID-19, nor did Ismail Sabri or Minister for Entrepreneurship Development and Cooperative Noh Omar due to them self-quarantining after being in contact with undisclosed COVID-19 infected contacts.

### September: Reconvening of parliament, MoU on bipartisan cooperation

On 10 September 2021, the cabinet agreed to implement key reforms like an Anti-Party Hopping Bill, equal membership in parliamentary committees, consulting on every Bill, having the Opposition Leader the same amenities as a cabinet minister, limiting a prime minister's term to 10 years and speeding up an amendment for 18-year-olds to vote and stand in elections. The following day, the opposition indicated its willingness to accept the deal in the interest of the country.
On 12 September 2021, the government led by Prime Minister Ismail Sabri Yaakob and opposition led by Leader of the Opposition Anwar Ibrahim agreed to sign a Memorandum of Understanding (MoU) on bipartisan cooperation and proposed reforms for greater political cooperation and stability during the COVID-19 pandemic. The MoU was signed the following day with elections not expected before 31 July 2022. Media commentary noted the significant milestone for Malaysian politics, given bipartisan cooperation has not occurred in the history of the country.

### October–December: Elections in Malacca and Sarawak

The Malacca State Legislative Assembly was dissolved on 4 October when four members withdrew support for Chief Minister Sulaiman Md Ali, triggering the 2021 Malacca state election. The government announced it would seek expert advice over whether the election can be held safely given the ongoing COVID-19 pandemic, or whether a state-wide state of emergency could be introduced to postpone it. The state election was carried out 20 November 2021 with strict Standard Operating Procedures, where Barisan Nasional won with a two-thirds majority of 21 seats in the Malacca State Legislative Assembly.
On 3 November 2021, Istana Negara announced that Yang di-Pertuan Agong Al-Sultan Abdullah Ri'ayatuddin Al-Mustafa Billah Shah consented to lift the state of emergency, thus the Sarawak State Legislative Assembly dissolved automatically and the state election was to be held within 60 days to elect a new state government. On 18 December 2021, GPS won with a two-thirds majority, winning 76 of 82 contested seats in the Sarawak State Legislative Assembly.

## 2022
### January–March: Elections in Johor

The snap election was called prematurely after the government led by Menteri Besar Hasni Mohammad had lost a simple majority in the legislature, being left with a minority government of just 28 seats, above one seat against the 27 seats of the opposition following the death of Kempas assemblyman and former Menteri Besar Osman Sapian on 21 December 2021 before the dissolution. The Sultan of Johor, Sultan Ibrahim Ismail consented to the dissolution of the Johor State Legislative Assembly on 22 January 2022, paving the way for state polls within 60 days.
On 12 March, Barisan Nasional (BN) continued its landslide winning streak in recent state elections, winning 40 seats and a two-thirds majority. Pakatan Harapan (PH) suffered heavy losses, winning only 12 seats. Perikatan Nasional (PN) won just 3 seats. The Malaysian United Democratic Alliance (MUDA) won 1 seat in its election debut.

### April–July: UMNO leadership crisis

On 24 June, Pasir Salak MP Tajuddin Abdul Rahman was removed from UMNO supreme council. After his removal decision, Tajuddin accepted the decision and held a press conference to reveal the UMNO leadership crisis, which includes that UMNO was going to split between two camps, which are Zahid's camp and Ismail's camp; UMNO President, Zahid Hamidi's attempt to become PM and SD declaration for Anwar to become PM that happened during 2020 and 2021. Tajuddin also asked for Zahid's resignation as UMNO President for good because Zahid is currently facing a corruption trial in court.

### August–November: Constitutional amendment and general election

A constitutional amendment was passed, which prohibits members of parliament from switching political parties. Several UMNO lawmakers began calling for a snap election before the end of 2022 to resolve ongoing infighting in the party and obtain a stronger mandate, with the UMNO Supreme Council agreeing to this by the end of September. On 10 October 2022, Ismail Sabri announced that the 14th Parliament had been dissolved to pave way for the upcoming 15th general election, which would be held within 60 days.
On 20 October, the Election Commission revealed the polling date for the 15th general election set on 19 November.
On 19 November, for the first time in Malaysian history, the results of the 2022 election resulted in a hung Parliament whereby no alliance had gained enough seats to form the next government. While the far-right, Islamist Malaysian Islamic Party won the most number of seats for a single party in the election, the Pakatan Harapan coalition led by Anwar Ibrahim won the highest number of seats for a coalition in the Dewan Rakyat, but former Prime Minister Muhyiddin Yassin and leader of the Perikatan Nasional coalition claimed to have a sufficient majority to be appointed as prime minister. Negotiations between party members and party leaders are taking place to determine if there is a single leader who can command the confidence of a majority of MPs, for subsequent appointment as the 10th Prime Minister of Malaysia. The Yang di-Pertuan Agong, Al-Sultan Abdullah, gave all party leaders and coalition leaders a deadline of 2 pm on Monday, 21 November 2022 MST, to submit the name of their preferred candidate for prime minister, to the Speaker of the Dewan Rakyat. The deadline was further extended by 24 hours until Tuesday, 22 November 2022. Barisan Nasional announced on Tuesday, 22 November that they will not support either PH or PN in the formation of the federal government.
The royal palace stated that after the Yang di-Pertuan Agong reviewed the nominations for prime minister, he found that "no member of parliament has the majority support to be appointed prime minister", so the Yang di-Pertuan Agong summoned Anwar and Muhyiddin to meet him. After the meeting, Muhyiddin said that the Yang di-Pertuan Agong proposed a unity government between Pakatan Harapan and Perikatan National, but Muhyiddin rejected it as Perikatan National "will not cooperate" with Pakatan Harapan. Instead, PN met some members of BN at St Regis Hotel. Meanwhile, Anwar acknowledged that the prime minister had yet to be determined, while stating that "given time, I think we will secure a simple majority".
On 23 November, the Yang di-Pertuan Agong met with BN and GPS leaders in the royal palace. After discontent from Sarawak over GPS working with PN, GPS stated that it was up to the Yang di-Pertuan Agong to appoint the Prime Minister; while Parti Warisan voiced support for a government with PH and BN. GRS leader Hajiji Noor stated that GRS would abide by the Yang di-Pertuan Agong's wishes on forming a new government, including if a unity government is formed. On 24 November, Ahmad Maslan of UMNO stated that the party's supreme council has agreed to follow the wishes of the Yang di-Pertuan Agong for BN to join a unity government which is not led by PN. Considering these final decisions, PH chairman Anwar Ibrahim finally was sworn in as Malaysia's 10th Prime Minister at 5 pm MST on 24 November 2022, by the Yang di-Pertuan Agong, Al-Sultan Abdullah.

The Sultan of Johor, Ibrahim Ismail of Johor ordered all 56 members of the legislative assembly to meet him on 26 February. The assembly session that was scheduled to be held on 5 March was postponed as a result. All the assemblypersons were asked to sign SD to state their preference whether to form a new coalition government or to allow Pakatan Harapan to continue governing the state.
On 27 February 2020, the private secretary to the Sultan, Jaba Mohd Noah, announced that a new coalition will govern the state after gaining a simple majority of 28 assemblymen against 26 who supported Pakatan Harapan. Two assemblymen, BERSATU's Mazlan Bujang and Amanah's Salahuddin Ayub failed to state their preference as they did not meet the Sultan as ordered. The new coalition was slated to consist of MLAs from BERSATU, UMNO, MIC, PAS and several others whose party allegiance were not mentioned. However, a day later Pakatan Harapan challenged the new coalition's claim of majority control and stated that it too had the support of 28 assemblymen, including Salahuddin Ayub and PKR assemblyman Chong Fat Full who was rumoured to have been one of 28 assemblymen that signed a SD in support of the new coalition. The new Menteri Besar of Johor, Hasni Mohammad from UMNO, was sworn in on the evening of 28 February in front of the Sultan at Istana Bukit Serene, Johor Bahru. On 4 March, PKR assemblyman from Pemanis, Chong Fat Full formally announced his exit from his party to become a Perikatan-friendly independent, thus resulting in Perikatan Nasional effectively controlling 29 seats in the state assembly against Harapan's 27.
On 14 May 2020, the Johor state assembly convened. Sultan Ibrahim Ismail addressed the assembly and called on politicians not to create a "virus" of divisiveness and discord that would infect the rest of the country in the midst of the COVID-19 pandemic. The Sultan also reminded all assemblymen to set a good example by maintaining decorum and discipline, in contrast to the disruptions in the Perak and Malacca assemblies earlier in the week. Earlier, on 11 May, Johor Pakatan Harapan announced that they cancelled a no confidence motion in the Menteri Besar in response to the Sultan's plea, and Speaker Suhaizan Kayat of Amanah remained in his position amid earlier reports of his removal by the Perikatan government. On 3 June, following new reports of Pakatan Harapan plotting to retake control of the state government, Sultan Ibrahim threatened to dissolve the assembly and hold a new election.
On 28 August 2020, Chong Fat Full joins BERSATU.
On 4 September 2020, Osman Sapian BERSATU membership has been voided with immediate effect after he was spotted stumping for Pejuang during the 2020 Slim by-election campaign period. However at same time BERSATU Secretary-General Hamzah Zainudin says, Osman Sapian still remains a member of BERSATU. He said for now, Osman would only be called to answer charges regarding allegations of helping the Independent candidate campaign in the recent Slim State Assembly (DUN) by-election (PRK), and no action has yet been taken. He died on 21 December 2021 at the age of 69 from the complications of the stroke he suffer earlier.
On 27 February 2021, three Amanah assemblyman from Senggarang, Serom, and Mahkota joined PKR.
After Osman Sapian died on 21 December 2021, speculation arises about Johor state election should be held due to government seats only 28 left while Pakatan Harapan seats 27 in the state assembly.
On 18 January 2022, Pakatan Harapan rejects Johor state elections and bargains on 'Stability Commitment'
On 22 January 2022, Menteri Besar of Johor Hasni Mohammad said Johor will see the implementation of State Elections in the near future. Sultan Ibrahim Ismail agreed to sign the dissolution letter of the Johor State Assembly effective today to make way for the State Election, to be held.
On 23 January 2022, Johor state assembly Speaker Suhaizan Kayat of Amanah signing the Letter and Proclamation of the dissolution of the Johor state assembly.
On 27 January 2022, Mazlan Bujang announced that he resigned as Division Chairman of BERSATU of Tebrau and himself as well as 23 Tebrau BERSATU branch chairmen and action committee members decided to leave the party and throw their support behind Barisan Nasional (BN) and the leadership of Menteri Besar of Johor Hasni Mohammad with immediate effect to "give way to a more stable political environment and for the betterment of the Johor people in general". He also claimed that he would carry on to serve the people without a political position and failure of the two previous Menteris Besar from Pakatan Harapan (PH) to lead the Johor state administration and the failure of both parties to nominate a better Johor Menteri Besar candidate as well as he felt disrespected of his removal as Johor BERSATU Chairman and did not send any representative to the meetings he had chaired even though Muhyiddin had signed his promotion letter as the reasons as well. Muhyiddin then lashed out at Mazlan by asking where is his honour and sarcastically asked him to bring 200000 members to leave BERSATU as well.
On 29 January 2022, Larkin assemblyman Izhar Ahmad quit BERSATU. He said one of the main reasons he resigned was that he had lost confidence in party president Muhyiddin Yassin. He will no longer contest in the Larkin state constituency or in any other constituency, however, will join UMNO.

On 6 March 2022, Johor Lama assemblyman Rosleli Jahari said that he has left BERSATU and will be requesting to rejoin UMNO. Rosleli, who was not selected as a candidate to defend his seat, said that he has lost confidence in BERSATU, its president Muhyiddin Yassin and his administration.

Rumors are rife that there are other names who have also been nominated as the new Menteri Besar of Johor. Among them are the names Onn Hafiz Ghazi and Dr. Mohd. Puad Zarkashi.

In Malacca, the legislative assembly was caught in a deadlock as both Pakatan Harapan and the opposition Barisan Nasional held 13 seats each after BERSATU left the then-ruling coalition. The Chief Minister of Malacca, Adly Zahari met the Yang di-Pertua Negeri of Malacca, Mohd Khalil Yaakob on 26 February to brief him on the current political situation. On 27 February, the state government announced in a press conference that they will preserve the status quo and will continue to operate as usual. However, the assembly session that was scheduled to be held on 6 March was postponed.
On 2 March 2020, Barisan Nasional's Malacca state chairman, Abdul Raouf Yusof attended a meeting with the Yang di-Pertua Negeri. In a press conference held in the evening, he confirmed that Pakatan Harapan had lost their majority in the legislative assembly and Perikatan Nasional will form a new government. The new coalition government had the support of 17 state assemblymen. On the same day, Adly Zahari met with the Yang di-Pertua Negeri and suggested that the state assembly be dissolved and to trigger a state election in accordance with Article 7 (4) of the state constitution, but Adly's suggestion was rejected.
On 3 March 2020, Adly held a press conference, in which he stated that he did not resign from his post. However, he was informed that he was no longer chief minister and was dismissed on the previous evening. The new chief minister of Malacca, Sulaiman Md Ali from UMNO was sworn in on the evening of 9 March 2020.
On 11 May 2020, the state assembly convened and the Perikatan administration moved a motion of no confidence in Speaker Omar Jaafar of PKR, which led to heated verbal exchanges and insults between both sides of the assembly. Example included PN Independent MP Norhizam Hassan Baktee shouting "babi" ("pig") repetitively to DAP representative Low Chee Leong in response to the latter's "pengkhianat" ("traitor") remark. The Speaker adjourned the sitting. Later, the assembly reconvened with only Perikatan assemblymen and declared Ab Rauf Yusoh of UMNO as the new Speaker. The ousted speaker said Malacca Pakatan Harapan is contesting the legality of the new Speaker's appointment.

On 4 October 2021, Four Malacca assemblymen declared that they have lost confidence in Chief Minister Sulaiman Md Ali's leadership. The assemblymen are former Malacca Chief Minister Idris Haron, Nor Azman Hassan, Norhizam Hassan Baktee and Noor Effandi Ahmad. Idris said the move was due to a series of decisions not implemented by the state government, which he added portrayed Malacca as a 'flip flop' state. State UMNO Liaison Committee chairman Ab Rauf Yusoh said the membership of Idris Haron and Nor Azman Hassan in UMNO was automatically dropped after being involved in the movement to overthrow the existing Malacca State Government. UMNO president Ahmad Zahid Hamidi proposed that the Malacca State Assembly be dissolved to make way for state elections to be held. The state elections will also give the people of the state the opportunity to elect a new government in the future.
On 5 October 2021, Idris Haron says Pakatan Harapan (PH) leaders should have the opportunity to take over the Malacca state government. The former Chief Minister said there was no need for the state election to be held as the 15th general election would be held in a year and a half. He said he personally rejected UMNO's proposal to hold a State Election (PRN) to resolve the state's political crisis. He, however, left the issue to the discretion of the Yang Dipertua Negeri, Mohd Ali Rustam to decide whether the State Legislative Assembly should be dissolved or elect a new Chief Minister from among the PH leaders. On the same day Malacca Assembly speaker disclosed that Malacca Chief Minister, Sulaiman Md Ali, took steps to dissolve the State Legislative Assembly starting 4 October 2021, in an effort to resolve the political crisis in the state. The dissolution of the Melaka state assembly was made after Sulaiman lost the majority of support, following the actions of four state assemblymen from the government bloc, withdrawing support for his leadership yesterday. The decision to dissolve the state assembly was made after the proposal submitted by Sulaiman received the approval of the Yang di-Pertua Negeri, Mohd Ali Rustam. In a separate press conference, PN Malacca chief Rafiq Naizmohideen announced immediate loss of Noor Effandi Ahmad's membership in BERSATU. The declaration was made due to his apparent cooperation with PH by being together with PH in a previous press conference on 4 October.

### Economy

The Ringgit also weakened against US dollar, traded at 4.22, their lowest in months. However, the market bounced back on the next day, trading at 0.78% higher on mid-day.

### COVID-19 pandemic

Following significant increases in COVID-19 cases in the country originating from the Tablighi Jamaat gathering at "Masjid Jamek Sri Petaling" in Kuala Lumpur, attention has been directed at the failure of the leadership of the country preventing such large gatherings from being held and containing the spread of the cluster case.
Until 24 February, Malaysia was under a Pakatan Harapan (PH) government, which Ministry of Health under Dzulkefly Ahmad had collaborated with Director-General of Health Noor Hisham Abdullah to prepare for the intake of COVID-19 patients, and had overseen the first month of the outbreak since 25 January with low volumes of cases, primarily imported. The Tabligh gathering, held from 27 February to 1 March, occurred within a week after the start of a major political crisis, which saw the collapse of the PH government on 24 February as a result of the defection of the Malaysian United Indigenous Party (PPBM) from the PH coalition, and an absence of a government until the formation of an unelected Perikatan Nasional (PN) government comprising a coalition of Opposition parties on 29 February. The Health Ministry would not have a minister for over two weeks until the appointment of Adham Baba on 10 March, just as spikes in cases began to be reported.

### Monarchy

Media outlets have noted the considerable involvement of Abdullah of Pahang in the political crisis. The Monarchies of Malaysia generally have minimal involvement in the country's politics, and some commentary suggesting it may pave the way for Abdullah, or monarchy itself, to have greater political influence in future. The Guardian described Abdullah's appointment of Muhyiddin, overturning of the 2018 election result, in March 2020 as a "royal coup".
