A constituency Labour Party (CLP) is an organisation of members of the British Labour Party who live in a particular UK parliamentary constituency in England and Wales. 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.
For much of the Labour Party's history, especially during the 1980s, CLPs were perceived as the more left wing faction in the Labour Party, with the unions being a more moderate or pragmatic force.
A CLP's main decision-making body is normally its General Committee or All Member Meeting. Day-to-day management is generally carried out by the Executive Committee (EC).
The Labour Party Rule Book establishes the CLP offices as chair, vice-chair, vice-chair/membership, secretary, Youth Officer, treasurer, women’s officer and ethnic minorities officer. These officers are referred to as the Key Officers.
CLPs may appoint additional "functional officers" such as a campaign co-ordinator, a political education and training officer, an information technology officer, a disability officer, a trade union liaison officer and a fundraising officer who may attend meetings of the Executive Committee (without voting power if they are not otherwise EC delegates).
The CLP elects representatives to national Party structures, including delegates to Labour Party Conference, and it nominates candidates for election to other Party positions such as the National Policy Forum and the National Executive Committee, as well as Party structures within Scotland, Wales or the appropriate English region.
As a result of changes proposed as part of the Party's 21st Century Party review, some CLPs have chosen to make changes in the way that they run. Some CLPs have merged the GC and EC into a single committee, whilst some CLPs have abolished the GC entirely and organize all-member meetings to take decisions. Other CLPs, particularly in urban areas divided between a number of constituencies, have chosen to combine their activities with neighbouring CLPs.
