Anthony Crosland bequeathed a significant intellectual legacy to the Labour Party including his celebrated treatise The Future of Socialism published sixty years ago. In this timely book, Patrick Diamond argues that Crosland continues to serve as a vital reference point for today’s Labour Party. He considers a wide range of Crosland’s writings on the economy and politics, relating his ideas to ideological debates taking place within the Labour Party about egalitarian social democracy, electoral strategy, the European question, and the importance of progressive liberalism on the British centre-left. This is the first substantial work to fully consider Crosland’s legacy for British social democracy. Written in a clear and persuasive way, it will appeal to a broad audience of thinkers and activists with an interest in the history of the Labour Party and the British Left.
