It alone possesses legislative supremacy and thereby ultimate power over all other political bodies in the UK and its territories. Its head is the Sovereign of the United Kingdom ( currently Queen Elizabeth II ) and its seat is the Palace of Westminster in the City of Westminster, one of the boroughs of the British capital, London. The parliament is bicameral, consisting of an upper house ( the House of Lords ) and a lower house ( the House of Commons ). The Sovereign forms the third component of the legislature ( the Queen - in - Parliament ). The House of Lords includes two different types of members : the Lords Spiritual, consisting of the most senior bishops of the Church of England, and the Lords Temporal, consisting mainly of life peers, appointed by the Sovereign on the advice of the Prime Minister, and of 92 hereditary peers, sitting either by virtue of holding a royal office, or by being elected by their fellow hereditary peers. Prior to the opening of the Supreme Court in October 2009, the House of Lords also performed a judicial role through the Law Lords. The House of Commons is a democratically elected chamber with elections held at least every five years. The two Houses meet in separate chambers in the Palace of Westminster ( commonly known as the Houses of Parliament ) in London. By constitutional convention, all government ministers, including the Prime Minister, are members of the House of Commons or, less commonly, the House of Lords and are thereby accountable to the respective branches of the legislature. Most cabinet ministers ( Secretaries of State ) are from the Commons, whilst junior ministers can be from either House. However, it should be noted the Leader of the House of Lords must be a peer and is a cabinet position, usually combined with a paid position. The Parliament of Great Britain was formed in 1707 following the ratification of the Treaty of Union by Acts of Union passed by the Parliament of England and the Parliament of Scotland. At the start of the 19th century, Parliament was further enlarged by Acts of Union ratified by the Parliament of Great Britain and the Parliament of Ireland that abolished the latter and added 100 Irish MPs and 32 Lords to the former to create the Parliament of the United Kingdom of Great Britain and Ireland. The Royal and Parliamentary Titles Act 1927 formally amended the name to the `` Parliament of the United Kingdom of Great Britain and Northern Ireland '', five years after the secession of the Irish Free State. The UK parliament and its institutions have set the pattern for many democracies throughout the world, and it has been called `` the mother of parliaments ''. However, John Bright -- who coined the epithet -- used it with reference to a country ( England ) rather than a parliament. In theory, the UK 's supreme legislative power is vested in the Crown - in - Parliament. However, the Crown normally acts on the advice of the Prime Minister and the powers of the House of Lords are limited to delaying legislation ; thus power is de facto vested in the House of Commons. The general election 2017 occurred on 8 June and resulted in a hung parliament. The Conservative Party ( UK ) under Theresa May, may join with the Democratic Unionist Party in a confidence and supply arrangement. The final outcome of the election is speculated to be a collaboration of the Conservative 's 318 seats and the DUP 's 10 seats bringing the coalition over the 326 threshold for forming a government.

For a summary, see Parliament in the Making. Parliament of the United Kingdom of Great Britain and Ireland The United Kingdom of Great Britain and Ireland was created on 1 January 1801, by the merger of the Kingdoms of Great Britain and Ireland under the Acts of Union 1800. The principle of ministerial responsibility to the lower House did not develop until the 19th century -- the House of Lords was superior to the House of Commons both in theory and in practice. Members of the House of Commons ( MPs ) were elected in an antiquated electoral system, under which constituencies of vastly different sizes existed. Thus, the borough of Old Sarum, with seven voters, could elect two members, as could the borough of Dunwich, which had almost completely disappeared into the sea due to land erosion. Many small constituencies, known as pocket or rotten boroughs, were controlled by members of the House of Lords, who could ensure the election of their relatives or supporters. During the reforms of the 19th century, beginning with the Reform Act 1832, the electoral system for the House of Commons was progressively regularised. No longer dependent on the Lords for their seats, MPs grew more assertive. Parliament at night, with the London Eye visible at right The supremacy of the British House of Commons was established in the early 20th century. In 1909, the Commons passed the so - called `` People 's Budget '', which made numerous changes to the taxation system which were detrimental to wealthy landowners. The House of Lords, which consisted mostly of powerful landowners, rejected the Budget. On the basis of the Budget 's popularity and the Lords ' consequent unpopularity, the Liberal Party narrowly won two general elections in 1910. Using the result as a mandate, the Liberal Prime Minister, Herbert Henry Asquith, introduced the Parliament Bill, which sought to restrict the powers of the House of Lords. ( He did not reintroduce the land tax provision of the People 's Budget. ) When the Lords refused to pass the bill, Asquith countered with a promise extracted from the King in secret before the second general election of 1910 and requested the creation of several hundred Liberal peers, so as to erase the Conservative majority in the House of Lords. In the face of such a threat, the House of Lords narrowly passed the bill. The Parliament Act 1911, as it became, prevented the Lords from blocking a money bill ( a bill dealing with taxation ), and allowed them to delay any other bill for a maximum of three sessions ( reduced to two sessions in 1949 ), after which it could become law over their objections. However, regardless of the Parliament Acts of 1911 and 1949, the House of Lords has always retained the unrestricted power to veto any bill outright which attempts to extend the life of a parliament. Parliament of the United Kingdom of Great Britain and Northern Ireland The Government of Ireland Act 1920 created the parliaments of Northern Ireland and Southern Ireland and reduced the representation of both parts at Westminster. The number of Northern Ireland seats was increased again after the introduction of direct rule in 1973. The Irish Free State became independent in 1922, and in 1927 parliament was renamed the Parliament of the United Kingdom of Great Britain and Northern Ireland. Further reforms to the House of Lords were made in the 20th century. The Life Peerages Act 1958 authorised the regular creation of life peerage dignities. By the 1960s, the regular creation of hereditary peerage dignities had ceased ; thereafter, almost all new peers were life peers only. The House of Lords Act 1999 removed the automatic right of hereditary peers to sit in the Upper House, although it made an exception for 92 of them to be elected to life - terms by the other hereditary peers, with by - elections upon their death. The House of Lords is now a chamber that is subordinate to the House of Commons. Additionally, the Constitutional Reform Act 2005 led to abolition of the judicial functions of the House of Lords with the creation of the new Supreme Court of the United Kingdom in October 2009. Composition and powers The legislative authority, the Crown - in - Parliament, has three separate elements : the Monarch, the House of Lords, and the House of Commons. No individual may be a member of both Houses, and members of the House of Lords are legally barred from voting in elections for members of the House of Commons. Royal Assent of the Monarch is required for all Bills to become law, and certain Delegated Legislation must be made by the Monarch by Order in Council. The Crown also has executive powers which do not depend on Parliament, through prerogative powers, including the power to make treaties, declare war, award honours, and appoint officers and civil servants. In practice these are always exercised by the monarch on the advice of the Prime Minister and the other ministers of HM Government. The Prime Minister and government are directly accountable to Parliament, through its control of public finances, and to the public, through the election of members of parliament. The Monarch also appoints the Prime Minister, who then forms a government from members of the Houses of Parliament. This must be someone who could command a majority in a confidence vote in the House of Commons. In the past the monarch has occasionally had to make a judgment, as in the appointment of Alec Douglas - Home in 1963 when it was thought that the incumbent Prime Minister, Harold Macmillan, had become ill with terminal cancer. However, today the monarch is advised by the outgoing Prime Minister as to whom he or she should offer the position next. The Upper House is formally styled `` The Right Honourable The Lords Spiritual and Temporal in Parliament Assembled '', the Lords Spiritual being bishops of the Church of England and the Lords Temporal being Peers of the Realm. The Lords Spiritual and Lords Temporal are considered separate `` estates '', but they sit, debate and vote together. Since the Parliament Acts 1911 and 1949, the powers of the House of Lords have been very much less than those of the House of Commons. All bills except money bills are debated and voted upon in the House of Lords ; however, by voting against a bill, the House of Lords can only delay it for a maximum of two parliamentary sessions over a year. After that time, the House of Commons can force the Bill through without the Lords ' consent, under the Parliament Acts. The House of Lords can also hold the government to account through questions to government ministers and the operation of a small number of select committees. The highest court in England & Wales and in Northern Ireland used to be a committee of the House of Lords, but it became an independent supreme court in 2009. The Lords Spiritual formerly included all of the senior clergymen of the Church of England -- archbishops, bishops, abbots and mitred priors. Upon the Dissolution of the Monasteries under Henry VIII the abbots and mitred priors lost their positions in Parliament. All diocesan bishops continued to sit in Parliament, but the Bishopric of Manchester Act 1847, and later Acts, provide that only the 26 most senior are Lords Spiritual. These always include the incumbents of the `` five great sees '', namely the Archbishop of Canterbury, the Archbishop of York, the Bishop of London, the Bishop of Durham and the Bishop of Winchester. The remaining 21 Lords Spiritual are the most senior diocesan bishops, ranked in order of consecration, although the Lords Spiritual ( Women ) Act 2015 makes time - limited provision for vacancies to be filled by women who are bishops. The Lords Temporal are all members of the Peerage. Formerly, they were all hereditary peers. The right of some hereditary peers to sit in Parliament was not automatic : after Scotland and England united into Great Britain in 1707, it was provided that all peers whose dignities had been created by English kings could sit in Parliament, but those whose dignities had been created by Scottish kings were to elect a limited number of `` representative peers ''. A similar arrangement was made in respect of Ireland when it was united with Great Britain in 1801, but when southern Ireland left the United Kingdom in 1922 the election of Irish representative peers ceased. By the Peerage Act 1963, the election of Scottish representative peers also ended, and all Scottish peers were granted the right to sit in Parliament. Under the House of Lords Act 1999, only life peerages ( that is to say, peerage dignities which can not be inherited ) automatically entitle their holders to seats in the House of Lords. Of the hereditary peers, only 92 -- the Earl Marshal, the Lord Great Chamberlain and the 90 elected by other peers -- retain their seats in the House. The Commons, the last of the `` estates '' of the Kingdom, are represented in the House of Commons, which is formally styled `` The Honourable The Commons in Parliament Assembled '' ( `` commons '' coming not from the term `` commoner '', but from commune, the old French term for a district ). In 2016, the House consists of 650 members. Each `` Member of Parliament '' or `` MP '' is chosen by a single constituency by the First - Past - the - Post electoral system. Universal adult suffrage exists for those 18 and over ; citizens of the United Kingdom, and those of the Republic of Ireland and Commonwealth nations resident in the United Kingdom, are qualified to vote, unless they are in prison at the time of the elections. The term of members of the House of Commons depends on the term of Parliament, a maximum of five years ; a general election, during which all the seats are contested, occurs after each dissolution ( see below ). All legislation must be passed by the House of Commons to become law and it controls taxation and the supply of money to the government. Government ministers ( including the Prime Minister ) must regularly answer questions in the House of Commons and there are a number of select committees that scrutinise particular issues and the workings of the government. There are also mechanisms that allow members of the House of Commons to bring to the attention of the government particular issues affecting their constituents. State Opening Main article : State Opening of Parliament The State Opening of Parliament is an annual event that marks the commencement of a session of the Parliament of the United Kingdom. It is held in the House of Lords Chamber and, before 2012, took place in November or December, or in a general election year, when the new Parliament first assembled. From 2012 onwards, the ceremony has taken place in May or June. Leading 17th century Parliamentarian John Hampden is one of the Five Members annually commemorated Motioned by the Monarch, the Lord Great Chamberlain raises his wand of office to signal to Black Rod, who is charged with summoning the House of Commons and has been waiting in the Commons lobby. Black Rod turns and, under the escort of the Door - keeper of the House of Lords and an inspector of police, approaches the doors to the Chamber of the Commons. In 1642, King Charles I stormed into the House of Commons in an unsuccessful attempt to arrest the Five Members, who included the celebrated English patriot and leading Parliamentarian John Hampden. This action sparked the English Civil War. The wars established the constitutional rights of Parliament, a concept legally established in the Glorious Revolution in 1688 and the subsequent Bill of Rights 1689. Since then, no British monarch has entered the House of Commons when it is in session. On Black Rod 's approach, the doors are slammed shut against him, symbolising the rights of parliament and its independence from the monarch. He then strikes with the end of his ceremonial staff ( the Black Rod ) three times on the closed doors of the Commons Chamber. He is then admitted, and announces the command of the monarch for the attendance of the Commons. The monarch reads a speech, known as the Speech from the Throne, which is prepared by the Prime Minister and his or her cabinet members, outlining the Government 's agenda for the coming year. The speech reflects the legislative agenda for which the Cabinet seeks the agreement of both Houses of Parliament. After the monarch leaves, each Chamber proceeds to the consideration of an `` Address in Reply to Her Majesty 's Gracious Speech ''. But first, each House considers a bill pro forma to symbolise their right to deliberate independently of the monarch. In the House of Lords, the bill is called the Select Vestries Bill, while the Commons equivalent is the Outlawries Bill. The Bills are considered for the sake of form only, and do not make any actual progress. Procedure See also the stages of a bill section in Acts of Parliament in the United Kingdom Both houses of the British Parliament are presided over by a speaker, the Speaker of the House for the Commons and the Lord Speaker in the House of Lords. For the Commons, the approval of the Sovereign is theoretically required before the election of the Speaker becomes valid, but it is, by modern convention, always granted. The Speaker 's place may be taken by three deputies, known as the Chairman, First Deputy Chairman and Second Deputy Chairman of Ways and Means. ( They take their name from the Committee of Ways and Means, of which they were once presiding officers, but which no longer exists. ) Prior to July 2006, the House of Lords was presided over by a Lord Chancellor ( a Cabinet member ), whose influence as Speaker was very limited ( whilst the powers belonging to the Speaker of the House of Commons are vast ). However, as part of the Constitutional Reform Act 2005, the position of Speaker of the House of Lords ( as it is termed in the Act ) was separated from the office of Lord Chancellor ( the office which has control over the judiciary as a whole ), though the Lords remain largely self - governing. Decisions on points of order and on the disciplining of unruly members are made by the whole body in the Upper House, but by the Speaker alone in the Lower House. Speeches in the House of Lords are addressed to the House as a whole ( using the words `` My Lords '' ), but those in the House of Commons are addressed to the Speaker alone ( using `` Mr Speaker '' or `` Madam Speaker '' ). Speeches may be made to both Houses simultaneously. Both Houses may decide questions by voice vote ; members shout out `` Aye ! '' and `` No ! '' in the Commons -- or `` Content ! '' and `` Not - Content ! '' in the Lords -- and the presiding officer declares the result. The pronouncement of either Speaker may be challenged, and a recorded vote ( known as a division ) demanded. ( The Speaker of the House of Commons may choose to overrule a frivolous request for a division, but the Lord Speaker does not have that power. ) In each House, a division requires members to file into one of the two lobbies alongside the Chamber ; their names are recorded by clerks, and their votes are counted as they exit the lobbies to re-enter the Chamber. The Speaker of the House of Commons is expected to be non-partisan, and does not cast a vote except in the case of a tie ; the Lord Speaker, however, votes along with the other Lords. Both Houses normally conduct their business in public, and there are galleries where visitors may sit. Term As at 2016, Parliament has a fixed term of 5 years. Originally there was no fixed limit on the length of a Parliament, but the Triennial Act 1694 set the maximum duration at three years. As the frequent elections were deemed inconvenient, the Septennial Act 1715 extended the maximum to seven years, but the Parliament Act 1911 reduced it to five. During the Second World War, the term was temporarily extended to ten years by Acts of Parliament. Since the end of the war the maximum has remained five years. Modern Parliaments, however, rarely continued for the maximum duration ; normally, they were dissolved earlier. For instance, the 52nd, which assembled in 1997, was dissolved after four years. The Septennial Act was repealed by the Fixed - term Parliaments Act 2011.

Following a general election, a new Parliamentary session begins. Parliament is formally summoned 40 days in advance by the Sovereign, who is the source of parliamentary authority. On the day indicated by the Sovereign 's proclamation, the two Houses assemble in their respective chambers. The Commons are then summoned to the House of Lords, where Lords Commissioners ( representatives of the Sovereign ) instruct them to elect a Speaker. The Commons perform the election ; on the next day, they return to the House of Lords, where the Lords Commissioners confirm the election and grant the new Speaker the royal approval in the Sovereign 's name. The business of Parliament for the next few days of its session involves the taking of the oaths of allegiance. Once a majority of the members have taken the oath in each House, the State Opening of Parliament may take place. The Lords take their seats in the House of Lords Chamber, the Commons appear at the Bar ( at the entrance to the Chamber ), and the Sovereign takes his or her seat on the throne. The Sovereign then reads the Speech from the Throne -- the content of which is determined by the Ministers of the Crown -- outlining the Government 's legislative agenda for the upcoming year. Thereafter, each House proceeds to the transaction of legislative business. By custom, before considering the Government 's legislative agenda, a bill is introduced pro forma in each House -- the Select Vestries Bill in the House of Lords and the Outlawries Bill in the House of Commons. These bills do not become laws ; they are ceremonial indications of the power of each House to debate independently of the Crown. After the pro forma bill is introduced, each House debates the content of the Speech from the Throne for several days. Once each House formally sends its reply to the Speech, legislative business may commence, appointing committees, electing officers, passing resolutions and considering legislation. A session of Parliament is brought to an end by a prorogation. There is a ceremony similar to the State Opening, but much less well - known to the general public. Normally, the Sovereign does not personally attend the prorogation ceremony in the House of Lords ; he or she is represented by Lords Commissioners. The next session of Parliament begins under the procedures described above, but it is not necessary to conduct another election of a Speaker or take the oaths of allegiance afresh at the beginning of such subsequent sessions. Instead, the State Opening of Parliament proceeds directly. To avoid the delay of opening a new session in the event of an emergency during the long summer recess, Parliament is no longer prorogued beforehand, but only after the Houses have reconvened in the autumn ; the State Opening follows a few days later. Each Parliament comes to an end, after a number of sessions, in anticipation of a general election. Parliament is dissolved by virtue of the Fixed - term Parliaments Act 2011. Prior to that, dissolution was effected by the Sovereign, always on the advice of the Prime Minister. The Prime Minister could seek dissolution at a time politically advantageous to his or her party. If the Prime Minister loses the support of the House of Commons, Parliament will dissolve and a new election will be held. Parliaments can also be dissolved if two - thirds of the House of Commons votes for an early election. Formerly, the demise of the Sovereign automatically brought a Parliament to an end, the Crown being seen as the caput, principium, et finis ( beginning, basis and end ) of the body, but this is no longer the case. The first change was during the reign of William and Mary, when it was seen to be inconvenient to have no Parliament at a time when succession to the Crown could be disputed, and an Act was passed that provided that a Parliament was to continue for six months after the death of a Sovereign, unless dissolved earlier. Under the Representation of the People Act 1867 Parliament can now continue for as long as it would otherwise have done in the event of the death of the Sovereign. After each Parliament concludes, the Crown issues writs to hold a general election and elect new members of the House of Commons, though membership of the House of Lords does not change. Legislative functions Parliament meets in the Palace of Westminster. Laws can be made by Acts of the United Kingdom Parliament. While Acts can apply to the whole of the United Kingdom including Scotland, due to the continuing separation of Scots law many Acts do not apply to Scotland and may be matched either by equivalent Acts that apply to Scotland alone or, since 1999, by legislation set by the Scottish Parliament relating to devolved matters. This has led to a paradox known as the West Lothian question. The existence of a devolved Scottish Parliament means that while Westminster MPs from Scotland may vote directly on matters that affect English constituencies, they may not have much power over their laws affecting their own constituency. Since there is no devolved `` English Parliament '', the converse is not true. While any Act of the Scottish Parliament may be overturned, amended or ignored by Westminster, in practice this has yet to happen. Legislative Consent Motions enables the UK Parliament to vote on issues normally devolved to Scotland, Wales or Northern Ireland, as part of United Kingdom legislation. Laws, in draft form known as bills, may be introduced by any member of either House. A bill introduced by a Minister is known as a `` Government Bill '' ; one introduced by another member is called a `` Private Member 's Bill ''. A different way of categorising bills involves the subject. Most bills, involving the general public, are called `` public bills ''. A bill that seeks to grant special rights to an individual or small group of individuals, or a body such as a local authority, is called a `` Private Bill ''. A Public Bill which affects private rights ( in the way a Private Bill would ) is called a `` Hybrid Bill '', although those that draft bills take pains to avoid this. Private Members ' Bills make up the majority of bills, but are far less likely to be passed than government bills. There are three methods for an MP to introduce a Private Member 's Bill. The Private Members ' Ballot ( once per Session ) put names into a ballot, and those who win are given time to propose a bill. The Ten Minute Rule is another method, where MPs are granted ten minutes to outline the case for a new piece of legislation. Standing Order 57 is the third method, which allows a bill to be introduced without debate if a day 's notice is given to the Table Office. Filibustering is a danger, as an opponent of a bill can waste much of the limited time allotted to it. Private Members ' Bills have no chance of success if the current government opposes them, but they are used in moral issues : the bills to decriminalise homosexuality and abortion were Private Members ' Bills, for example. Governments can sometimes attempt to use Private Members ' Bills to pass things it would rather not be associated with. `` Handout bills '' are bills which a government hands to MPs who win Private Members ' Ballots. Each Bill goes through several stages in each House. The first stage, called the first reading, is a formality. At the second reading, the general principles of the bill are debated, and the House may vote to reject the bill, by not passing the motion `` That the Bill be now read a second time ''. Defeats of Government Bills are extremely rare, the last being in 2005. Following the second reading, the bill is sent to a committee. In the House of Lords, the Committee of the Whole House or the Grand Committee are used. Each consists of all members of the House ; the latter operates under special procedures, and is used only for uncontroversial bills. In the House of Commons, the bill is usually committed to a Public Bill Committee, consisting of between 16 and 50 members, but the Committee of the Whole House is used for important legislation. Several other types of committees, including Select Committees, may be used, but rarely. A committee considers the bill clause by clause, and reports the bill as amended to the House, where further detailed consideration ( `` consideration stage '' or `` report stage '' ) occurs. However, a practice which used to be called the `` kangaroo '' ( Standing Order 32 ) allows the Speaker to select which amendments are debated. This device is also used under Standing Order 89 by the committee chairman, to restrict debate in committee. Once the House has considered the bill, the third reading follows. In the House of Commons, no further amendments may be made, and the passage of the motion `` That the Bill be now read a third time '' is passage of the whole bill. In the House of Lords further amendments to the bill may be moved. After the passage of the third reading motion, the House of Lords must vote on the motion `` That the Bill do now pass ''. Following its passage in one House, the bill is sent to the other House. If passed in identical form by both Houses, it may be presented for the Sovereign 's Assent. If one House passes amendments that the other will not agree to, and the two Houses can not resolve their disagreements, the bill fails. However, since the passage of the Parliament Act 1911 the power of the House of Lords to reject bills passed by the House of Commons has been restricted, and further restrictions were placed by the Parliament Act 1949. If the House of Commons passes a public bill in two successive sessions, and the House of Lords rejects it both times, the Commons may direct that the bill be presented to the Sovereign for his or her Assent, disregarding the rejection of the Bill in the House of Lords. In each case, the bill must be passed by the House of Commons at least one calendar month before the end of the session. The provision does not apply to bills originated in the House of Lords, to bills seeking to extend the duration of a Parliament beyond five years, or to Private Bills. A special procedure applies in relation to bills classified by the Speaker of the House of Commons as `` Money Bills ''. A Money Bill concerns solely national taxation or public funds ; the Speaker 's certificate is deemed conclusive under all circumstances. If the House of Lords fails to pass a Money Bill within one month of its passage in the House of Commons, the Lower House may direct that the Bill be submitted for the Sovereign 's Assent immediately. Even before the passage of the Parliament Acts, the Commons possessed pre-eminence in cases of financial matters. By ancient custom, the House of Lords may not introduce a bill relating to taxation or Supply, nor amend a bill so as to insert a provision relating to taxation or Supply, nor amend a Supply Bill in any way. The House of Commons is free to waive this privilege, and sometimes does so to allow the House of Lords to pass amendments with financial implications. The House of Lords remains free to reject bills relating to Supply and taxation, but may be over-ruled easily if the bills are Money Bills. ( A bill relating to revenue and Supply may not be a Money Bill if, for example, it includes subjects other than national taxation and public funds ). The last stage of a bill involves the granting of the Royal Assent. Theoretically, the Sovereign may either grant the Royal Assent ( that is, make the bill a law ) or withhold it ( that is, veto the bill ). In modern times the Sovereign always grants the Royal Assent, using the Norman French words `` La Reyne le veult '' ( the Queen wishes it ; `` Le Roy '' instead in the case of a king ). The last refusal to grant the Assent was in 1708, when Queen Anne withheld her Assent from a bill `` for the settling of Militia in Scotland '', in the words `` La reyne s'avisera '' ( the Queen will think it over ). Thus, every bill obtains the assent of all three components of Parliament before it becomes law ( except where the House of Lords is over-ridden under the Parliament Acts 1911 and 1949 ). The words `` BE IT ENACTED by the Queen 's ( King 's ) most Excellent Majesty, by and with the advice and consent of the Lords Spiritual and Temporal, and Commons, in this present Parliament assembled, and by the authority of the same, as follows : - '', or, where the House of Lords ' authority has been over-ridden by use of the Parliament Acts, the words `` BE IT ENACTED by The Queen 's ( King 's ) most Excellent Majesty, by and with the advice and consent of the Commons in this present Parliament assembled, in accordance with the provisions of the Parliament Acts 1911 and 1949, and by the authority of the same, as follows : - '' appear near the beginning of each Act of Parliament. These words are known as the enacting formula. Judicial functions Prior to the creation of the Supreme Court of the United Kingdom in October 2009, Parliament also used to perform several judicial functions. The Queen - in - Parliament constituted the highest court in the realm for most purposes, but the Privy Council had jurisdiction in some cases ( for instance, appeals from ecclesiastical courts ). The jurisdiction of Parliament arose from the ancient custom of petitioning the Houses to redress grievances and to do justice. The House of Commons ceased considering petitions to reverse the judgements of lower courts in 1399, effectively leaving the House of Lords as the court of last resort. In modern times, the judicial functions of the House of Lords were performed not by the whole House, but by a group of `` Lords of Appeal in Ordinary '' ( judges granted life peerage dignities under the Appellate Jurisdiction Act 1876 by the Sovereign ) and by `` Lords of Appeal '' ( other peers with experience in the judiciary ). However, under the Constitutional Reform Act 2005, these judicial functions were transferred to the newly created Supreme Court in 2009, and the Lords of Appeal in Ordinary became the first Justices of the Court. Peers who hold high judicial office are no longer allowed to vote or speak in the Lords until they retire as Justices. In the late 19th century, Acts allowed for the appointment of Scottish Lords of Appeal in Ordinary and ended appeal in Scottish criminal matters to the House of Lords, so that the High Court of Justiciary became the highest criminal court in Scotland. There is an argument that the provisions of Article XIX of the Union with England Act 1707 prevent any Court outside Scotland from hearing any appeal in criminal cases : `` And that the said Courts or any other of the like nature after the Unions shall have no power to Cognosce Review or Alter the Acts or Sentences of the Judicatures within Scotland or stop the Execution of the same. '' Nowadays the House of Lords legislative committee usually has a minimum of two Scottish Judges to ensure that some experience of Scots law is brought to bear on Scottish appeals in civil cases, from the Court of Session. Certain other judicial functions have historically been performed by the House of Lords. Until 1948, it was the body in which peers had to be tried for felonies or high treason ; now, they are tried by normal juries. When the House of Commons impeaches an individual, the trial takes place in the House of Lords. Impeachments are now rare ; the last one occurred in 1806. In 2006, a number of MPs attempted to revive the custom, having signed a motion for the impeachment of Tony Blair, but this was unsuccessful. Relationship with the UK Government The British Government is answerable to the House of Commons. However, neither the Prime Minister nor members of the Government are elected by the House of Commons. Instead, the Queen requests the person most likely to command the support of a majority in the House, normally the leader of the largest party in the House of Commons, to form a government. So that they may be accountable to the Lower House, the Prime Minister and most members of the Cabinet are, by convention, members of the House of Commons. The last Prime Minister to be a member of the House of Lords was Alec Douglas - Home, 14th Earl of Home, who became Prime Minister in 1963. To adhere to the convention under which he was responsible to the Lower House, he disclaimed his peerage and procured election to the House of Commons within days of becoming Prime Minister. Governments have a tendency to dominate the legislative functions of Parliament, by using their in - built majority in the House of Commons, and sometimes using their patronage power to appoint supportive peers in the Lords. Formerly, no - one could be a member of Parliament while holding an Office of profit under the Crown, thus maintaining the separation of powers, but the principle has been gradually eroded. Until 1919, Members of Parliament who were appointed to ministerial office lost their right to sit in the House of Commons and had to seek re-election. The rule survives in the House of Commons Disqualification Act 1975 which specifies a number of state positions that make an individual ineligible to serve as a member of Parliament. The only vestige of the principle is the process of resignation from the House of Commons. In practice, governments can pass any legislation ( within reason ) in the Commons they wish, unless there is major dissent by MPs in the governing party. But even in these situations, it is highly unlikely a bill will be defeated, though dissenting MPs may be able to extract concessions from the government. In 1976, Lord Hailsham created a now widely used name for this behaviour, in an academic paper called `` elective dictatorship ''. Parliament controls the executive by passing or rejecting its Bills and by forcing Ministers of the Crown to answer for their actions, either at `` Question Time '' or during meetings of the parliamentary committees. In both cases, Ministers are asked questions by members of their Houses, and are obliged to answer. Although the House of Lords may scrutinise the executive through Question Time and through its committees, it can not bring down the Government. A ministry must always retain the confidence and support of the House of Commons. The Lower House may indicate its lack of support by rejecting a Motion of Confidence or by passing a Motion of No Confidence. Confidence Motions are generally originated by the Government to reinforce its support in the House, whilst No Confidence Motions are introduced by the Opposition. The motions sometimes take the form `` That this House has ( no ) confidence in Her Majesty 's Government '' but several other varieties, many referring to specific policies supported or opposed by Parliament, are used. For instance, a Confidence Motion of 1992 used the form, `` That this House expresses the support for the economic policy of Her Majesty 's Government. '' Such a motion may theoretically be introduced in the House of Lords, but, as the Government need not enjoy the confidence of that House, would not be of the same effect as a similar motion in the House of Commons ; the only modern instance of such an occurrence involves the ' No Confidence ' motion that was introduced in 1993 and subsequently defeated. Many votes are considered votes of confidence, although not including the language mentioned above. Important bills that form part of the Government 's agenda ( as stated in the Speech from the Throne ) are generally considered matters of confidence. The defeat of such a bill by the House of Commons indicates that a Government no longer has the confidence of that House. The same effect is achieved if the House of Commons `` withdraws Supply '', that is, rejects the budget. Where a Government has lost the confidence of the House of Commons, the Prime Minister is obliged either to resign, or seek the dissolution of Parliament and a new general election. Where a Prime Minister has ceased to retain a majority in that vote and requests a dissolution, the Sovereign can in theory reject his request, forcing his resignation and allowing the Leader of the Opposition to be asked to form a new government. This power is used extremely rarely. The conditions that should be met to allow such a refusal are known as the Lascelles Principles. These conditions and principles are constitutional conventions arising from the Sovereign 's reserve powers as well as longstanding tradition and practice, not laid down in law. In practice, the House of Commons ' scrutiny of the Government is very weak. Since the first - past - the - post electoral system is employed in elections, the governing party tends to enjoy a large majority in the Commons ; there is often limited need to compromise with other parties. Modern British political parties are so tightly organised that they leave relatively little room for free action by their MPs. In many cases, MPs may be expelled from their parties for voting against the instructions of party leaders. During the 20th century, the Government has lost confidence issues only three times -- twice in 1924, and once in 1979. Parliamentary questions See also : Question Time § United Kingdom, and Prime Minister 's Questions In the United Kingdom, question time in the House of Commons lasts for an hour each day from Monday to Thursday ( 2 : 30 to 3 : 30 pm on Mondays, 11 : 30 am to 12 : 30 pm on Tuesdays and Wednesdays, and 9 : 30 to 10 : 30 am on Thursdays ). Each Government department has its place in a rota which repeats every five weeks. The exception to this sequence are the Business Questions ( Questions to the Leader of House of Commons ), in which questions are answered each Thursday about the business of the House the following week. Also, Questions to the Prime Minister takes place each Wednesday from noon to 12 : 30 pm. In addition to government departments, there are also questions to the Church commissioners. Additionally, each Member of Parliament is entitled to table questions for written answer. Written questions are addressed to the Ministerial head of a government department, usually a Secretary of State, but they are often answered by a Minister of State or Parliamentary Under Secretary of State. Written Questions are submitted to the Clerks of the Table Office, either on paper or electronically, and answers are recorded in The Official Report ( Hansard ) so as to be widely available and accessible. In the House of Lords, a half - hour is set aside each afternoon at the start of the day 's proceedings for Lords ' oral questions. A peer submits a question in advance, which then appears on the Order Paper for the day 's proceedings. The Lord shall say : `` My Lords, I beg leave to ask the Question standing in my name on the Order Paper ''. The Minister responsible then answers the question. The Lord is then allowed to ask a supplementary question and other peers ask further questions on the theme of the original put down on the order paper. ( For instance, if the question regards immigration, Lords can ask the Minister any question related to immigration during the allowed period ). Sovereignty Parliament Buildings, Stormont, Northern Ireland is home to the Northern Ireland Assembly. Several different views have been taken of Parliament 's sovereignty. According to the jurist Sir William Blackstone, `` It has sovereign and uncontrollable authority in making, confirming, enlarging, restraining, abrogating, repealing, reviving, and expounding of laws, concerning matters of all possible denominations, ecclesiastical, or temporal, civil, military, maritime, or criminal... it can, in short, do every thing that is not naturally impossible. '' A different view has been taken by the Scottish judge Lord Cooper of Culross. When he decided the 1953 case of MacCormick v. Lord Advocate as Lord President of the Court of Session, he stated, `` The principle of unlimited sovereignty of Parliament is a distinctively English principle and has no counterpart in Scottish constitutional law. '' He continued, `` Considering that the Union legislation extinguished the Parliaments of Scotland and England and replaced them by a new Parliament, I have difficulty in seeing why the new Parliament of Great Britain must inherit all the peculiar characteristics of the English Parliament but none of the Scottish. '' Nevertheless, he did not give a conclusive opinion on the subject. Thus, the question of Parliamentary sovereignty appears to remain unresolved. Parliament has not passed any Act defining its own sovereignty. A related possible limitation on Parliament relates to the Scottish legal system and Presbyterian faith, preservation of which were Scottish preconditions to the creation of the unified Parliament. Since the Parliament of the United Kingdom was set up in reliance on these promises, it may be that it has no power to make laws that break them. Parliament 's power has often been eroded by its own Acts. Acts passed in 1921 and 1925 granted the Church of Scotland complete independence in ecclesiastical matters. More recently, its power has been restricted by membership of the European Union, which has the power to make laws enforceable in each member state. In the Factortame case, the European Court of Justice ruled that British courts could have powers to overturn British legislation contravening European law. Parliament has also created national devolved parliaments and assemblies with differing degrees of legislative authority in Scotland, Wales and Northern Ireland. Parliament still has the power over areas for which responsibility lies with the devolved institutions, but would gain the agreement of those institutions to act on their behalf. Similarly, it has granted the power to make regulations to Ministers of the Crown, and the power to enact religious legislation to the General Synod of the Church of England. ( Measures of the General Synod and, in some cases proposed statutory instruments made by ministers, must be approved by both Houses before they become law. ) In every case aforementioned, authority has been conceded by Act of Parliament and may be taken back in the same manner. It is entirely within the authority of Parliament, for example, to abolish the devolved governments in Scotland, Wales and Northern Ireland or to leave the EU. However, Parliament also revoked its legislative competence over Australia and Canada with the Australia and Canada Acts : although the Parliament of the United Kingdom could pass an Act reversing its action, it would not take effect in Australia or Canada as the competence of the Imperial Parliament is no longer recognised there in law. One well - recognised exception to Parliament 's power involves binding future Parliaments. No Act of Parliament may be made secure from amendment or repeal by a future Parliament. For example, although the Act of Union 1800 states that the Kingdoms of Great Britain and Ireland are to be united `` forever '', Parliament permitted southern Ireland to leave the United Kingdom in 1922. Privileges Main article : Parliamentary privilege Each House of Parliament possesses and guards various ancient privileges. The House of Lords relies on inherent right. In the case of the House of Commons, the Speaker goes to the Lords ' Chamber at the beginning of each new Parliament and requests representatives of the Sovereign to confirm the Lower House 's `` undoubted '' privileges and rights. The ceremony observed by the House of Commons dates to the reign of King Henry VIII. Each House is the guardian of its privileges, and may punish breaches thereof. The extent of parliamentary privilege is based on law and custom. Sir William Blackstone states that these privileges are `` very large and indefinite '', and can not be defined except by the Houses of Parliament themselves. The foremost privilege claimed by both Houses is that of freedom of speech in debate ; nothing said in either House may be questioned in any court or other institution outside Parliament. Another privilege claimed is that of freedom from arrest ; at one time this was held to apply for any arrest except for high treason, felony or breach of the peace but it now excludes any arrest on criminal charges ; it applies during a session of Parliament, and 40 days before or after such a session. Members of both Houses are no longer privileged from service on juries. Both Houses possess the power to punish breaches of their privilege. Contempt of Parliament -- for example, disobedience of a subpoena issued by a committee -- may also be punished. The House of Lords may imprison an individual for any fixed period of time, but an individual imprisoned by the House of Commons is set free upon prorogation. The punishments imposed by either House may not be challenged in any court, and the Human Rights Act does not apply. Until at least 2015, members of the House of Commons also had the privilege of a separate seating area in the Palace of Westminster canteen, protected by a false partition labelled `` MPs only beyond this point '', so that they did not have to sit with canteen staff taking a break. This provoked mockery from a newly elected 20 - year - old MP who described it as `` ridiculous '' snobbery. Emblem The Crowned Portcullis of Parliament The quasi-official emblem of the Houses of Parliament is a crowned portcullis. The portcullis was originally the badge of various English noble families from the 14th century. It went on to be adopted by the kings of the Tudor dynasty in the 16th century, under whom the Palace of Westminster became the regular meeting place of Parliament. The crown was added to make the badge a specifically royal symbol. The portcullis probably first came to be associated with the Palace of Westminster through its use as decoration in the rebuilding of the Palace after the fire of 1512. However, at the time it was only one of many symbols. The widespread use of the portcullis throughout the Palace dates from the 19th century, when Charles Barry and Augustus Pugin used it extensively as a decorative feature in their designs for the new Palace built following the disastrous 1834 fire. The crowned portcullis came to be accepted during the 20th century as the emblem of both houses of parliament. This was simply a result of custom and usage rather than a specific decision. The emblem now appears on official stationery, publications and papers, and is stamped on various items in use in the Palace of Westminster, such as cutlery, silverware and china. Various shades of red and green are used for visual identification of the House of Lords and the House of Commons.
