Parliament of the United Kingdom The Parliament of the United Kingdom is the supreme legislative body in the United Kingdom and holds sovereignty across England, Wales, Scotland, and Northern Ireland. It is a bicameral institution composed of the elected House of Commons and the appointed House of Lords, meeting at the Palace of Westminster in Westminster, London. Its evolution reflects landmark events such as the Magna Carta, the English Civil War, the Glorious Revolution, and the Acts of Union 1707.
Parliamentary development traces from medieval assemblies such as the Witan and the Great Council, through milestones including the Magna Carta (1215), the creation of the Model Parliament (1295), and the constitutional crises epitomised by the English Civil War and the execution of Charles I of England. The post-Restoration era saw tensions resolved by the Glorious Revolution and the Bill of Rights 1689, while the Acts of Union 1707 and the Acts of Union 1800 merged legislatures with Scotland and Ireland, respectively. The 19th and 20th centuries brought reform via the Reform Act 1832, the Parliament Act 1911, the Parliament Act 1949, and suffrage expansions tied to movements led by figures like Emmeline Pankhurst and events such as World War I. Devolution and constitutional changes in the late 20th and early 21st centuries produced the Scottish Parliament, the Senedd Cymru, and the Northern Ireland Assembly following agreements like the Good Friday Agreement.
Parliament comprises two chambers and the Crown in Parliament represented by Charles III; the lower chamber, the House of Commons, consists of 650 Members of Parliament elected from constituencies under the First Past the Post system, dominated historically by parties such as the Conservative Party (UK), the Labour Party (UK), the Liberal Democrats (UK), and regional parties including the Scottish National Party, Plaid Cymru, and the Democratic Unionist Party. The upper chamber, the House of Lords, includes life peers nominated via the House of Lords Appointments Commission, hereditary peers like those retaining seats after the House of Lords Act 1999, and twenty-six Lords Spiritual from the Church of England. Officers and officials include the Speaker of the House of Commons, the Leader of the House of Commons (UK), the Leader of the House of Lords, and the Clerk of the House of Commons, while the parliamentary estate encompasses the Palace of Westminster, Norman Shaw North, and the Elizabeth Tower.
Parliament exercises legislative authority through statute law enacted as Acts of Parliament, supervises the executive via mechanisms such as Prime Ministerial questions exemplified by the Prime Minister of the United Kingdom, and controls public finance by approving supply and taxation following precedents like the Bill of Rights 1689 and the Parliament Acts. Judicial functions have been curtailed by reforms including the creation of the Supreme Court of the United Kingdom and the separation of judicial roles from the House of Lords under the Constitutional Reform Act 2005. Parliament's privileges, including freedom of speech within proceedings, derive from historical charters and contested episodes such as the Clerk of the House of Commons v. Smith disputes and political crises like the Westminster MP expenses scandal.
Legislation typically begins as a government Bill introduced by a Minister such as the Chancellor of the Exchequer or a private Member's Bill from backbenchers; Bills undergo stages—First Reading, Second Reading, Committee Stage, Report Stage, and Third Reading—in both the Commons and the House of Lords, with amendments reconciled via mechanisms like the Parliament Acts or parliamentary ping-pong. Financial legislation respects the Commons' primacy as established after the Glorious Revolution, and delegated legislation is scrutinised through instruments such as statutory instruments considered by the Joint Committee on Statutory Instruments. Key procedural figures include the Clerk of the Parliaments, the Leader of the House of Commons (UK), and committee chairs, while major legislative programmes have been associated with administrations like those of Margaret Thatcher, Tony Blair, and Theresa May.
Parliamentary scrutiny operates through select committees such as the Public Accounts Committee, the Treasury Select Committee, the Foreign Affairs Select Committee, and departmental committees aligned to Secretaries of State like the Secretary of State for Foreign, Commonwealth and Development Affairs. The House of Lords contributes via secondary legislation scrutiny committees, the Constitution Committee, and crossbench expertise from peers including former judges and civil servants, while joint committees address constitutional matters exemplified by inquiries into the European Union (Withdrawal) Act 2018 and the Investigatory Powers Act 2016. High-profile hearings have summoned figures like Nigel Farage, Boris Johnson, and senior civil servants during investigations into events such as the 2016 United Kingdom European Union membership referendum and the COVID-19 pandemic response.
Parliament’s constitutional relationship with the Crown in Parliament involves formal procedures such as Royal Assent conferred by the Monarch and ceremonial events like the State Opening of Parliament presided over by Charles III using the Speech from the Throne drafted by the government. Devolution has created legislatures including the Scottish Parliament, the Senedd Cymru, and the Northern Ireland Assembly with powers distinct from reserved matters retained at Westminster under statutes like the Scotland Act 1998 and the Government of Wales Act 1998, while ongoing disputes over sovereignty and competence have involved institutions such as the Supreme Court of the United Kingdom and legal tests applied in cases like the Miller (No. 1) litigation and Miller (No. 2). Inter-parliamentary relations extend to bodies like the Inter-Parliamentary Union and UK delegations to the Parliamentary Assembly of the Council of Europe.
