In 1976, Harold Wilson announces his shock resignation as Prime Minister and the Labour government has a sudden power vacuum. Three feuding cabinet giants – Roy Jenkins, Denis Healey and Tony Crosland – meet to discuss who should succeed him.

All three are ostensibly friends, all contemporaries at Oxford and are embarking on their historic quest to make the Labour party Britain’s natural party of government. The Gang Of Three tells the story of how, in a changing Britain, their fractured friendships and bitter rivalries came to destroy their mutual goal, instead ushering in eighteen years of Tory rule.
