what does the prime minister of the uk do
Prime Minister of the United Kingdom The Prime Minister is the head of Her Majesty's Government in the United Kingdom.[6][better source needed] As the "Head of Her Majesty's Government" the modern Prime Minister leads the Cabinet (the Executive). In addition the Prime Minister leads a major political party and generally commands a majority in the House of Commons (the lower house of the legislature). As such the incumbent wields both legislative and executive powers. Under the British system there is a unity of powers rather than separation.[7] In the House of Commons, the Prime Minister guides the law-making process with the goal of enacting the legislative agenda of their political party. In an executive capacity the Prime Minister appoints (and may dismiss) all other cabinet members and ministers, and co-ordinates the policies and activities of all government departments, and the staff of the Civil Service. The Prime Minister also acts as the public "face" and "voice" of Her Majesty's Government, both at home and abroad. Solely upon the advice of the Prime Minister, the Sovereign exercises many statutory and prerogative powers, including high judicial, political, official and Church of England ecclesiastical appointments; the conferral of peerages and some knighthoods, decorations and other honours.[8]
House of Commons of the United Kingdom Although it does not formally elect the prime minister, the position of the parties in the House of Commons is of overriding importance. By convention, the prime minister is answerable to, and must maintain the support of, the House of Commons. Thus, whenever the office of prime minister falls vacant, the Sovereign appoints the person who has the support of the House, or who is most likely to command the support of the Houseâ€”normally the leader of the largest party in the Commons, while the leader of the second-largest party becomes the Leader of the Opposition. Since 1963, by convention, the prime minister is always a member of the House of Commons, rather than the House of Lords.
