House of Commons of the United Kingdom has part(s) of the class Member of Parliament
Peers as ministers
By convention, ministers are members of either the House of Commons or the House of Lords. A handful have been appointed from outside Parliament, but in most cases they then entered Parliament in a by-election or by receiving a peerage (being made a peer). Since 1902, all prime ministers have been members of the Commons; the sole exception was during the long summer recess in 1963: Alec Douglas-Home, then the 14th Earl of Home, disclaimed his peerage (under a new mechanism which remains in force) three days after becoming prime minister. The new session of Parliament was delayed to await the outcome of his by-election, which happened to be already under way due to a recent death. As anticipated, he won that election, which was for the highest-majority seat in Scotland among his party; otherwise he would have been constitutionally obliged to resign.
Since 1990, almost all cabinet ministers, save for three whose offices are an intrinsic part of the House of Lords, have belonged to the Commons.
Few major cabinet positions (except Lord Privy Seal, Lord Chancellor and Leader of the House of Lords) have been filled by a peer in recent times. Notable exceptions are Peter Carington, 6th Lord Carrington, who served as Foreign Secretary from 1979 to 1982; David Young, Lord Young of Graffham, who was appointed Employment Secretary in 1985; Lord Mandelson, who served as Business Secretary; Lord Adonis, who served as Transport Secretary; Baroness Amos, who served as International Development Secretary; Baroness Morgan of Cotes, who served as Culture Secretary; and Lord Goldsmith of Richmond Park, who is serving as Minister of State for Environment, Food and Rural Affairs and Minister of State for International Development. The elected status of members of the Commons (as opposed to the unelected Lords) and their direct accountability to that House, together with empowerment and transparency, ensures ministerial accountability. Responsible government is an international constitutional paradigm. The prime minister chooses the ministers, and may decide to remove them at any time, although the appointments and dismissals are formally made by the Sovereign.
