Born in 1920, Les Cannon quickly made his mark on the world of trade unionism. A keen supporter of the Communist Party in his early life, and an electrician by trade, Cannon held the position of Electrical Trades Union Executive Councillor from 1948-1954. However, in the wake of events in Hungary, Cannon became disillusioned with the Communist Party, leaving it in 1956. From then on, he began a campaign to uncover what he saw as a wide ranging plot by the Communists to rig ETU elections - this resulted in the famous 1961 trial, when Cannon's allegations were proved correct, and the then ETU General Secretary was forced to step down. Cannon became ETU General President in 1963, and also over-saw the union's merger with the Plumbing Trades Union, to form the Electrical, Electronic, Telecommunications and Plumbing Trades Union in 1968. Tragically, Cannon died of cancer in 1970, aged fifty, shortly before he was awarded a knighthood in the New Year's Honours List.
