House of Commons: Members

House of Commons: Members


  • Members of the House of Commons, known as Members of Parliament (MPs), represent constituencies from across the UK.
  • There are, as of 2020, 650 constituencies, each represented by one MP.
  • MPs are elected through a First Past the Post system, which is a type of plurality voting method.

Roles and Duties

  • Duties of MPs involve representing their constituents, legislation, and scrutinising the government.
  • Independent of party affiliations, MPs are mandated to represent the interests of all individuals living within their constituency.
  • They spend a significant time at Westminster, participating in debates and voting on legislation.
  • MPs often serve on parliamentary committees, focusing on specific areas of public policy, government functions, or legislative proposals.

Party Affiliations

  • Most MPs belong to one of the major political parties in the UK - the Conservative Party, the Labour Party, the Scottish National Party, or the Liberal Democrats.
  • However, there are also MPs from smaller regional parties and Independent MPs.
  • The party with the most MPs usually forms the government, with its leader serving as the Prime Minister.


  • MPs are accountable to their constituents and can lose their seats at a General Election or in a by-election (if one were to occur in their constituency).
  • Each term in office lasts up to five years, but it can be shortened if the Prime Minister calls an early election.
