This important and timely new book provides a thoroughly researched account of the rise of the left wing in the Labour Party in Britain during the 1970s and early 1980s and its marginalisation under the Kinnock leadership. It introduces the main currents on the Left and sets out their ideas, demands, achievements and limitations. '...this is an important book which asks crucial questions and provides valuable insights about the role of the Left within the Labour Party. No-one engaged in teaching British politics can afford to ignore it.' David J.Wilson, Leicester Polytechnic
