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 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.
In the United Kingdom, a member of Parliament (MP) is an individual elected to serve in the House of Commons, the lower house of the Parliament of the United Kingdom.

It was dissolved on 30 March 2015, being 25 working days ahead of the 2015 general election on 7 May 2015.
