Parliament of the United Kingdom
The Parliament of the United Kingdom of Great Britain and Northern Ireland, commonly known internationally as the UK Parliament, British Parliament, or Westminster Parliament, and domestically simply as Parliament, is the supreme legislative body of the United Kingdom, and the British Overseas Territories. It alone possesses legislative supremacy and thereby ultimate power over all other political bodies in the UK and the overseas territories. Parliament is bicameral but has three parts, consisting of the Sovereign (the Queen-in-Parliament), the House of Lords, and the House of Commons (the primary chamber). The two houses meet in the Palace of Westminster in the City of Westminster, one of the inner boroughs of the capital city, London.
List of political parties in the United Kingdom
Since then the Conservative and Labour parties have dominated British politics, and have alternated in government ever since. However, the UK is not quite a two-party system as other parties have significant support. The Liberal Democrats were the third largest party until the 2015 general election when they were overtaken by the Scottish National Party in terms of seats and UK political party membership, and by the UK Independence Party in terms of votes.
