The British parliamentary system is a form of government where the executive branch derives its legitimacy from and is accountable to the legislature, known as Parliament. This system consists of two houses: the House of Commons, which is made up of elected representatives, and the House of Lords, which includes appointed members and bishops. The leader of the government, called the Prime Minister, is usually the head of the majority party in the House of Commons. In this system, laws are proposed and debated in Parliament, and the government must maintain the confidence of the House of Commons to stay in power. If the government loses a vote of confidence, it may lead to a general election. The British parliamentary system emphasizes collaboration and debate, allowing for a dynamic political environment.
