The Parliament of the United Kingdom of Great Britain and Northern Ireland is the supreme legislative body of the United Kingdom, and may also legislate for the Crown Dependencies and the British Overseas Territories. It meets at the Palace of Westminster in London. Parliament possesses legislative supremacy and thereby holds ultimate power over all other political bodies in the United Kingdom and the Overseas Territories. While Parliament is bicameral, it has three parts: the sovereign (King-in-Parliament), the House of Lords, and the House of Commons. In theory, power is officially vested in the King-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 only delaying legislation; thus power is de facto vested in the House of Commons.
The politics of the United Kingdom functions within a constitutional monarchy where executive power is delegated by legislation and social conventions to a unitary parliamentary democracy. From this a hereditary monarch, currently King Charles III, serves as head of state while the Prime Minister of the United Kingdom, currently Rishi Sunak since 2022, serves as the elected head of government.
Monarchical systems of government have existed in Ireland from ancient times. In most of Ireland, this continued until 1949, when it transitioned to being the Republic of Ireland. Northern Ireland, as part of the United Kingdom, remains under a monarchical system of government.
The Parliament of Great Britain was formed in May 1707 following the ratification of the Acts of Union by both the Parliament of England and the Parliament of Scotland. The Acts ratified the treaty of Union which created a new unified Kingdom of Great Britain and created the parliament of Great Britain located in the former home of the English parliament in the Palace of Westminster, near the City of London. This lasted nearly a century, until the Acts of Union 1800 merged the separate British and Irish Parliaments into a single Parliament of the United Kingdom with effect from 1 January 1801.
The Kingdom of England was a sovereign state on the island of Great Britain from the early 10th century, when it emerged from various Anglo-Saxon kingdoms, until May 1, 1707, when it united with Scotland to form the Kingdom of Great Britain, which would later become the United Kingdom. The Kingdom of England was among the most powerful states in Europe during the medieval and early modern colonial periods.
Politics of England forms the major part of the wider politics of the United Kingdom, with England being more populous than all the other countries of the United Kingdom put together. As England is also by far the largest in terms of area and GDP, its relationship to the UK is somewhat different from that of Scotland, Wales or Northern Ireland. The English capital London is also the capital of the UK, and English is the dominant language of the UK. Dicey and Morris (p26) list the separate states in the British Islands. "England, Scotland, Northern Ireland, the Isle of Man, Jersey, Guernsey, Alderney, and Sark.... is a separate country in the sense of the conflict of laws, though not one of them is a State known to public international law." But this may be varied by statute.
The Parliament of Ireland was the legislature of the Lordship of Ireland, and later the Kingdom of Ireland, from 1297 until the end of 1800. It was modelled on the Parliament of England and from 1537 comprised two chambers: the House of Commons and the House of Lords. The Lords were members of the Irish peerage and bishops. The Commons was directly elected, albeit on a very restricted franchise. Parliaments met at various places in Leinster and Munster, but latterly always in Dublin: in Christ Church Cathedral, Dublin Castle, Chichester House (1661–1727), the Blue Coat School (1729–31), and finally a purpose-built Parliament House on College Green.
The Wars of the Three Kingdoms, sometimes known as the British Civil Wars, were a series of intertwined conflicts fought between 1639 and 1653 in the kingdoms of England, Scotland and Ireland, then separate entities united in a personal union under Charles I. They include the 1639 to 1640 Bishops' Wars, the First and Second English Civil Wars, the Irish Confederate Wars, the Cromwellian conquest of Ireland and the Anglo-Scottish War of 1650–1652. They resulted in victory for the Parliamentarian army, the execution of Charles I, the abolition of monarchy, and founding of the Commonwealth of England, a unitary state which controlled the British Isles until the Stuart Restoration in 1660.
In the United Kingdom (UK), each of the electoral areas or divisions called constituencies elects one member to the House of Commons.
The first Parliament of the Kingdom of Great Britain was established in 1707 after the merger of the Kingdom of England and the Kingdom of Scotland. It was in fact the 4th and last session of the 2nd Parliament of Queen Anne suitably renamed: no fresh elections were held in England or in Wales, and the existing members of the House of Commons of England sat as members of the new House of Commons of Great Britain. In Scotland, prior to the union coming into effect, the Scottish Parliament appointed sixteen peers and 45 Members of Parliaments to join their English counterparts at Westminster.
This is a list of the parliaments of the United Kingdom, of Great Britain and of England from 1660 to the present day, with the duration of each parliament. The NP number is the number counting forward from the creation of the United Kingdom in 1801 and Great Britain in 1707. Prior to that, the parliaments are counted from the Restoration in 1660.
Multi-member constituencies existed in the Parliament of the United Kingdom and its predecessor bodies in the component parts of the United Kingdom from the earliest era of elected representation until they were abolished by the Representation of the People Act 1948. Since the 1950 general election, all members of the House of Commons have been elected from single-member constituencies.
The 2009 European Parliament election was the United Kingdom's component of the 2009 European Parliament election, the voting for which was held on Thursday 4 June 2009. The election was held concurrently with the 2009 local elections in England. In total, 72 Members of the European Parliament were elected from the United Kingdom using proportional representation.
This is a list of the MPs for Irish constituencies, who were elected at the 1802 United Kingdom general election, to serve as members of the 2nd UK Parliament from Ireland, or who were elected at subsequent by-elections. There were 100 seats representing Ireland in this Parliament.
The following outline is provided as an overview of and topical guide to the United Kingdom:
The House of Commons of England was the lower house of the Parliament of England from its development in the 14th century to the union of England and Scotland in 1707, when it was replaced by the House of Commons of Great Britain after the 1707 Act of Union was passed in both the English and Scottish parliaments at the time. In 1801, with the union of Great Britain and Ireland, that house was in turn replaced by the House of Commons of the United Kingdom.
Elections in the Kingdom of Great Britain were principally general elections and by-elections to the House of Commons of Great Britain. General elections did not have fixed dates, as parliament was summoned and dissolved within the royal prerogative, although on the advice of the ministers of the Crown. The first such general election was that of 1708, and the last that of 1796.
