History of the Labour Party (UK)
The British Labour Party grew out of the trade union movement of the late 19th century and surpassed the Liberal Party as the main opposition to the Conservatives in the early 1920s. In the 1930s and 1940s, it stressed national planning, using nationalisation of industry as a tool, in line with Clause IV of the original constitution of the Labour Party which called for the "common ownership of the means of production, distribution, and exchange, and the best obtainable system of popular administration and control of each industry or service".

Clause IV is part of the Labour Party Rule Book, which sets out the aims and values of the British Labour Party. The original clause, adopted in 1918, called for common ownership of industry, and proved controversial in later years; Hugh Gaitskell attempted to remove the clause following Labour's loss in the 1959 general election.
