A new single volume history of the Communist Party of Great Britain examining the party from its foundations in 1920 to its demise in the early 1990s. Drawing on original research and a reading of specialist texts, the authors analyze the rise and fall of the party and evaluate its role on the left of British politics. Whilst sympathetic to the ideals and commitment of many British communist activists, the book is sharply critical of much of the actual practice of the party.
