Constituency Labour Party

A constituency Labour Party (CLP) is an organisation of members of the British Labour Party who live in a particular parliamentary constituency.

In England and Wales, CLP boundaries coincide with those for UK parliamentary constituencies. In Scotland, CLP boundaries align with constituencies of the Scottish Parliament. The Labour Party in Northern Ireland has, since February 2009, been organised as a province-wide constituency Labour Party which is yet to contest elections.[1] Labour International is a CLP for members of the British Labour Party who are currently living overseas.

For much of the Labour Party's history, especially during the 1980s, CLPs were perceived as relatively left wing, compared to the more moderate or pragmatic trade unions.[2]
