UK Parliament is the supreme legislative body of the United Kingdom, the Crown Dependencies and the British Overseas Territories. It alone possesses legislative supremacy and thereby ultimate power over all other political bodies in the UK and its territories. Located at the Palace of Westminster in London, it is a bicameral institution comprising an upper house, the House of Lords, and a lower house, the House of Commons.

History

The origins of the institution trace back to the early medieval councils of Anglo-Saxon kings, notably the Witan, and evolved through key historical moments. The Model Parliament of 1295, summoned by Edward I, established a representative template, while the English Civil War and the Glorious Revolution of 1688 were pivotal in shifting power from the monarchy. Landmark statutes like the Magna Carta, the Bill of Rights 1689, and the Acts of Union 1707 which united England and Scotland, formally shaped its constitutional foundations. The Parliament Acts 1911 and 1949 subsequently curtailed the power of the Lords, cementing the primacy of the Commons, and further reforms like the Life Peerages Act 1958 and the House of Lords Act 1999 modernised its membership.

Composition and membership

The institution is composed of two distinct houses. The House of Commons consists of 650 elected Members of Parliament (MPs) representing single-member constituencies across the United Kingdom, elected under the first-past-the-post system in a general election. The House of Lords is an unelected chamber, its membership comprising Lords Spiritual such as the Archbishop of Canterbury and senior bishops of the Church of England, and Lords Temporal including life peers appointed under the Life Peerages Act 1958, hereditary peers remaining after the House of Lords Act 1999, and Law Lords from the Judicial Committee of the Privy Council. The Sovereign, currently Charles III, is the third component, providing Royal Assent to make bills law.

Functions and powers

Its primary function is to scrutinise and pass legislation, known as Acts of Parliament. It holds the power to levy taxation, authorise government spending through the Budget, and provide scrutiny of the executive via mechanisms like Prime Minister's Questions and select committees. It is responsible for major constitutional matters, such as treaties like those governing European Union membership, and retains the power to declare war, as seen historically with conflicts like the Falklands War. It also serves as a forum for national debate on issues ranging from National Health Service policy to international affairs concerning NATO or the United Nations.

Procedure and workings

Legislation typically originates in the House of Commons, undergoing multiple readings, committee stages, and debates before being sent to the House of Lords for further scrutiny and amendment, in a process known as parliamentary ping-pong. Key officers include the Speaker of the Commons, who presides over debates, and the Lord Speaker in the upper house. Sessions are governed by Standing Orders and tradition, with the annual ceremonial opening conducted by the Sovereign who delivers the Speech from the Throne outlining the government's agenda. Committees like the Public Accounts Committee and the Liaison Committee conduct detailed investigative work.

Relationship with Government

By constitutional convention, the Government is drawn from and accountable to the House of Commons, with the Prime Minister typically being the leader of the party commanding a majority, as historically seen with figures like Winston Churchill, Margaret Thatcher, and Tony Blair. Ministers, including the Chancellor of the Exchequer and the Foreign Secretary, are primarily MPs or peers who must defend policies in their respective chambers. The principle of collective responsibility binds the government, while the official opposition, led by the Leader of the Opposition, challenges it through structures like the Shadow Cabinet. A government can fall if it loses a major vote, such as a confidence motion.

Parliamentary sovereignty

The doctrine of parliamentary sovereignty, articulated by constitutional theorists like A. V. Dicey, holds that it can make or unmake any law on any subject, and no other body, including the courts as established in cases like R (Jackson) v Attorney General, can override its legislation. This supremacy was demonstrated historically by statutes such as the Parliament Acts 1911 and 1949 and the European Union (Withdrawal) Act 2018. However, this absolute principle is now debated due to the influence of international agreements, the European Convention on Human Rights incorporated via the Human Rights Act 1998, and the devolved legislatures of Scotland, Wales, and Northern Ireland established by acts like the Scotland Act 1998.
