British politics is characterized by a parliamentary system, where the Prime Minister leads the government and is supported by the Cabinet. The Parliament consists of two houses: the House of Commons, made up of elected representatives, and the House of Lords, which includes appointed members and bishops. Political parties play a significant role, with the Conservative Party and the Labour Party being the two main parties. Other parties, such as the Liberal Democrats and regional parties like the Scottish National Party, also influence the political landscape. Elections are held regularly, allowing citizens to vote for their representatives.
