The government in the United Kingdom is divided into three branches—an executive, a legislature, and a judiciary. The legislature, called Parliament, is divided into two houses—the House of Commons and the House of Lords. Members of the House of Commons are elected, while members of the House of Lords are appointed. The executive consists of the Prime Minister, the leader of the majority party in Parliament, and other ministers. All ministers are a part of the Parliament; thus, all people in the executive branch are also in the legislative branch. In some cases, these officials may also serve in the judiciary. The highest judicial power in the United Kingdom is the Supreme Court, which can overturn decisions if they violate the constitutional tenets of the nation.
