The Members' Lobby is a hallway in the Palace of Westminster used by members of the Parliament of the United Kingdom. Members of Parliament may congregate here for discussions while not dealing with other business.
The Lobby is situated next to the House of Commons (the lower house), close to the central lobby, and is off-limits to members of the public during voting sessions. It hosts offices of government and opposition whips, who are responsible for organising voting along party lines.
Former British prime ministers are honoured with statues and busts in the Lobby. For example, in February 2007, a bronze statue of Margaret Thatcher was unveiled, close to a bust of her Conservative predecessor Edward Heath.
