Launched on a wave of euphoria in 1981, the SDP aroused the hopes and enthusiasm of millions of people. Promising to break the mould of British politics, its leaders included four of the most respected figures in British public life - Roy Jenkins, David Owen, Bill Rodgers, and Shirley Williams. But the SDP failed. Despite winning with the Liberals a quarter of the vote in two general elections, by the autumn of 1987 it had disintegrated
amidst acrimony and bitter in-fighting. This book, based on unprecedented access to the SDP's archive and extensive interviews with all the leading players, chronicles the party's
short but turbulent history and analyses in detail the reasons for its early success and its ultimate demise.
