an instrumental role in assembling centre-left ideas during and after World War II. The 1980s and the split of the Labour Party Although the Political Quarterly’s board from time to time contained occasional Conservatives and Liberals, and contributors had ranged from Mussolini to Trotsky, there was a tendency for most people associated with the journal to have some kind of affiliation to the Labour Party. This came under severe strain in the early 1980s, when the party itself split, with a breakaway group forming the short-lived Social Democratic Party. This split was reproduced within the Political Quarterlys Board. About half of the Board continued, along with the then chair, Bernard Crick, to stay with Labour, while others, including the editor at the time, Rudolf Klein, and one of the founders of the SDP, Shirley Williams, went with the new party. For a time, relations within the Board became tense, with proposals for new board members or editors being scrutinised suspiciously for their effects on the balance. The decision to have two editors dated from that time, with Colin Crouch (a Labour supporter) being appointed alongside Klein. On Klein’s retirement he was replaced by David Marquand, another SDP founder. The tensions subsided, the idea of having two editors being retained just in order to make the work less onerous.
