Between the wars, the response of the British Labour Party and Trades Union Congress to the problem of the unemployed was extremely limited. Committed to gradualist philosophies, the leaders of the labour movement were unwilling to attempt genuine socialist remedies in office, and, in opposition, to provide a militant leadership for the protest movement. The National Unemployed Workers' Movement, begun in 1921 and not finally dissolved until after the outbreak of the Second World War, was the only body which attempted to mobilise unemployed discontent. After 1926, the Labour Party Executive and the General Council of the TUC consistently refused to have any contact with this organisation on the grounds that, like the National Minority Movement and the later Rank-and-File Movement, the NUWM was merely a subsidiary of the British Communist Party. This article is an attempt to show that by a process of induction the Labour leaders branded the unemployed movement as a whole on the basis of the known Communist allegiance of a number of its leaders, and to demonstrate that they allowed themselves to become so sidetracked by the issue of whether or not the NUWM was a Communist front that their own efforts on behalf of the unemployed suffered in consequence.
