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.
Upper house
An upper house is one of two chambers of a bicameral legislature (or one of three chambers of a tricameral legislature), the other chamber being the lower house. The house formally designated as the upper house is usually smaller and often has more restricted power than the lower house. Examples of upper houses in countries include the United Kingdom's House of Lords, India's Rajya Sabha, Pakistan's Senate of Pakistan, Russia's Federation Council, Ireland's Seanad, Malaysia's Dewan Negara, Germany's Bundesrat, Switzerland's Council of States, the Australian Senate, the Dutch Eerste Kamer, and the United States Senate.
