House of Commons of the United Kingdom Accordingly, the House of Commons assumed its current title. Under the Parliament Act 1911, the Lords' power to reject legislation was reduced to a delaying power. The Government is solely responsible to the House of Commons and the Prime Minister stays in office only as long as he or she retains the support of a majority of the Commons. 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.
