Passages:
The Deputy Prime Minister of Croatia (officially the Vice President of the Government of the Republic of Croatia (Croatian: "Potpredsjednik/ Potpredsjednica Vlade Republike Hrvatske" )), is the official Deputy of the Prime Minister of Croatia.  Article 109 of the Constitution of Croatia states that the cabinet is to be made up of the Prime Minister, one or more Deputy Prime Ministers and other cabinet ministers.  According to convention, if the governing parliamentary majority is a coalition of parties, all junior partners in the coalition will usually be given one Deputy Prime Minister in the cabinet, with their rank usually being determined by the number of MPs the party has in Parliament.  The Deputy Prime Ministers are permitted to simultaneously hold a ministerial portfolio while in office, but may also serve without holding such a portfolio. The Prime Minister (Swedish: "statsminister" , literally "Minister of the State") is the head of government in Sweden.  Before the creation of the office of a Prime Minister in 1876, Sweden did not have a head of government separate from its head of state, namely the King, in whom the executive authority was vested.  Louis De Geer, the architect behind the new bicameral Riksdag of 1866 that replaced the centuries-old Riksdag of the Estates, became the first officeholder in 1876.  The current Prime Minister of Sweden is Stefan Löfven, leader of the Swedish Social Democratic Party.  Below is the list and statistics of Prime Ministers of Sweden since the creation of the office in 1876.  The list does not include acting prime ministers, the only example to date is Östen Undén who served as acting prime minister from 6 to 11 October 1946. Commonwealth Prime Ministers' Conference were biennial meetings of Prime Ministers of the United Kingdom and the Dominion members of the British Commonwealth of Nations.  Seventeen Commonwealth Prime Ministers' Conferences were held between 1944 and 1969.  As well, the prime ministers met for a Commonwealth Economic Conference in 1952.  These series of conferences were a continuation and regularisation of the earlier Imperial Conferences which had been held periodically from 1887 to 1937.  Since 1971, Commonwealth Heads of Government Meetings have been held. The 1948 Commonwealth Prime Ministers' Conference was the third Meeting of the Heads of Government of the British Commonwealth.  It was held in the United Kingdom in October 1948, and was hosted by that country's Prime Minister, Clement Attlee. The 1951 Commonwealth Prime Ministers' Conference was the fifth Meeting of the Heads of Government of the British Commonwealth.  It was held in the United Kingdom in January 1951, and was hosted by that country's Prime Minister, Clement Attlee. Clement Richard Attlee, 1st Earl Attlee, {'1': ", '2': ", '3': ", '4': "} (3 January 1883 – 8 October 1967) was a British Labour politician who served as Prime Minister of the United Kingdom from 1945 to 1951 and Leader of the Labour Party from 1935 to 1955.  In 1940, Attlee took Labour into the wartime coalition government and served under Winston Churchill, becoming the first person to hold the office of Deputy Prime Minister of the United Kingdom.  He went on to lead the Labour Party to an unexpected landslide victory at the 1945 general election; forming the first Labour majority government, and a mandate to implement its postwar reforms.  The 12.0% national swing from the Conservatives to Labour was unprecedented at that time and remains the largest ever achieved by any party at a general election in British electoral history.  He was re-elected with a narrow majority at the 1950 general election.  In the following year, Attlee called a snap general election, hoping to increase his parliamentary majority.  However, he was narrowly defeated by the Conservatives under the leadership of Winston Churchill; despite winning the most votes of any political party in any general election in British political history until the Conservative Party's fourth consecutive victory in 1992.  Attlee remains the longest-ever serving Leader of the Labour Party. The Government of Israel (officially: Hebrew: ממשלת ישראל‎ ‎ "Memshelet Yisrael") exercises executive authority in the State of Israel.  It consists of ministers who are chosen and led by the prime minister.  The composition of the government must be approved by a vote of confidence in the Knesset (the Israeli parliament).  Under Israeli law, the prime minister may dismiss members of the government, but must do so in writing, and new appointees must be approved by the Knesset.  Most ministers lead ministries, though some are ministers without portfolio.  Most ministers are members of the Knesset, though only the Prime Minister and the "designated acting prime minister" are required to be Knesset members.  Some ministers are also called deputy and vice prime ministers.  Unlike the designated acting prime minister, these roles have no statutory meanings.  The government operates in accordance with the Basic Law.  It meets on Sundays weekly in Jerusalem.  There may be additional meetings if circumstances require it.  The prime minister convenes these meetings. The 1946 Commonwealth Prime Ministers' Conference was the second Meeting of the Heads of Government of the British Commonwealth.

The deputy prime minister has throughout its history been responsible for helping the prime minister to handle Vietnam's internal policies.  Since Vietnam is a one-party state, with the Communist Party of Vietnam being the sole party allowed by the constitution, all the deputy prime ministers of the Democratic Republic and the Socialist Republic have been members of the party while holding office.  There are currently four deputy prime ministers; Nguyễn Xuân Phúc,
