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, the House of Lords, and the House of Commons. The three parts acting together to legislate may be described as the King-in-Parliament. 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.
The United Kingdom is a constitutional monarchy which, by legislation and convention, operates as a unitary parliamentary democracy. A hereditary monarch, currently King Charles III, serves as head of state while the Prime Minister of the United Kingdom, currently Sir Keir Starmer since 2024, serves as the elected head of government.
The 1983 United Kingdom general election was held on Thursday 9 June 1983. It gave the Conservative Party under the leadership of Margaret Thatcher the most decisive election victory since that of the Labour Party in 1945, with a majority of 144 seats and the first of two consecutive landslide victories.
The politics of Scotland operate within the constitution of the United Kingdom, of which Scotland is a country. Scotland is a democracy, being represented in both the Scottish Parliament and the Parliament of the United Kingdom since the Scotland Act 1998. Most executive power is exercised by the Scottish Government, led by the First Minister of Scotland, the head of government in a multi-party system. The judiciary of Scotland, dealing with Scots law, is independent of the legislature and the Scottish Government. Scots law is primarily determined by the Scottish Parliament. The Scottish Government shares some executive powers with the Scotland Office, a British government department led by the Secretary of State for Scotland.
There are five types of elections in the United Kingdom: elections to the House of Commons of the United Kingdom, elections to devolved parliaments and assemblies, local elections, mayoral elections, and police and crime commissioner elections. Within each of those categories, there may also be by-elections. Elections are held on Election Day, which is conventionally a Thursday, and under the provisions of the Dissolution and Calling of Parliament Act 2022 the timing of general elections can be held at the discretion of the prime minister during any five-year period. All other types of elections are held after fixed periods, though early elections to the devolved assemblies and parliaments can occur in certain situations. The five electoral systems used are: the single member plurality system (first-past-the-post), the multi-member plurality, the single transferable vote, the additional member system, and the supplementary vote.
The fifty-fifth Parliament of the United Kingdom was the legislature of the United Kingdom following the 2010 general election of members of parliament (MPs) to the House of Commons.
