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.
Unicameralism
Unicameral legislatures are also common in official Communist states such as the People's Republic of China and Cuba. Similarly, many formerly Communist states, such as Ukraine, Moldova and Serbia, have retained their unicameral legislatures, though others, such as Romania and Poland, adopted bicameral legislatures. Both the former Russian SFSR and the Union of Soviet Socialist Republics (USSR) were bicameral. The two chambers were the Soviet of Nationalities and the Soviet of the Union. The Russian Federation retained bicameralism after the dissolution of the USSR and the transition from existing socialism to capitalism.
