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.
Constitution of the United Kingdom
Parliament is bicameral, with two houses — the House of Commons and the House of Lords; the monarch formally forms a third element of Parliament (see Queen-in-Parliament). The House of Commons, which unlike the House of Lords is democratically elected, has supremacy by virtue of the Parliament Act 1911 and Parliament Act 1949. An Act of Parliament of the United Kingdom is primary legislation and Parliament can (and does) alter the British constitution by passing such Acts.
