Parliament of the United Kingdom

Parliament of the United Kingdom. The supreme legislative body of the United Kingdom, the Crown Dependencies, and the British Overseas Territories. It is a bicameral institution, comprising an upper house, the House of Lords, and a lower house, the House of Commons. The Sovereign, currently Charles III, forms the third component of the legislature, providing Royal Assent to transform bills into law.

History

The origins of Parliament trace back to the early medieval councils of Anglo-Saxon kings, notably the Witenagemot. The modern institution evolved from the Parliament of England, which was merged with the Parliament of Scotland through the Acts of Union 1707, forming the Parliament of Great Britain. Further expansion occurred with the Acts of Union 1800, which incorporated Ireland. Key historical developments include the English Civil War, the Glorious Revolution, and the passage of foundational statutes like the Magna Carta and the Bill of Rights 1689. The Parliament Acts 1911 and 1949 significantly curtailed the powers of the House of Lords, while the Life Peerages Act 1958 reformed its membership.

Composition and membership

The House of Commons consists of 650 elected Members of Parliament, each representing a single geographical constituency through the first-past-the-post system. The House of Lords is an unelected chamber, with membership including Lords Spiritual (senior bishops of the Church of England), Lords Temporal (life peers appointed under the Life Peerages Act 1958 and hereditary peers remaining from the House of Lords Act 1999), and Law Lords prior to the establishment of the Supreme Court of the United Kingdom. The Lord Speaker presides over the Lords, while the Speaker of the House of Commons chairs the lower house.

Functions and powers

Its primary function is the scrutiny and passage of legislation, known as Acts of Parliament. It holds the power to levy taxes, authorize government expenditure, and provide oversight of the executive through mechanisms like Prime Minister's Questions. Parliament also plays a key role in matters of war and peace, as seen in debates over conflicts like the Iraq War, and holds the constitutional authority to amend or repeal any previous legislation, a principle central to Parliamentary sovereignty.

Procedure and workings

Legislation typically originates as a bill in either house, undergoing multiple readings, committee stages, and debates. The State Opening of Parliament marks the beginning of a new parliamentary session, where the Sovereign delivers the King's Speech outlining the government's agenda. Key committees, such as the Public Accounts Committee and departmental select committees, conduct detailed scrutiny. Traditions like the Parliamentary Archives and the use of Hansard for official reports are integral to its workings, with proceedings held in the Palace of Westminster.

Relationship with the Government

By convention, the Government is drawn from and accountable to Parliament, specifically the House of Commons. The Prime Minister is the leader of the party that commands the confidence of the Commons, as demonstrated during events like the 2017 election. Ministers, including the Chancellor of the Exchequer, are regularly questioned in Parliament. A government that loses a major vote, such as a confidence motion, is typically expected to resign, as nearly occurred during the 1979 vote of no confidence.

Parliamentary sovereignty

This constitutional doctrine, famously expounded by A. V. Dicey, holds that Parliament has the absolute legal authority to make or unmake any law, and that no other body, including the courts, can override its legislation. This principle was tested in conflicts such as the English Civil War and debates over European Union law. While membership in the European Union and the incorporation of the European Convention on Human Rights via the Human Rights Act 1998 created tensions, statutes like the European Union (Withdrawal) Act 2018 have reasserted this sovereignty.
