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.
House of Commons
In the UK and Canada, the Commons holds much more legislative power than the respective upper house of parliament. The leader of the majority party in the House of Commons usually becomes the prime minister. Since 2010 the House of Commons of the United Kingdom has had 650 elected members, and since 2015 the House of Commons of Canada has had 338 members. The Commons' functions are to consider through debate new laws and changes to existing ones, authorise taxes, and provide scrutiny of the policy and expenditure of the Government. It has the power to give a Government a vote of no confidence.
