Abstract: | The article seeks to identify a neglected dimension of the ‘crisis’ and schism of British social democracy in the 1970s from within the ranks of the parliamentary Labour ‘right’ itself. Accounts of the so‐called ‘Labour right’ and its influential revisionist social democratic tradition have emphasized its generic cohesion and uniformity over contextual analysis of its inherent intellectual, ideological and political range and diversity. The article seeks to evaluate differential responses of Labour's ‘right‐wing’ and revisionist tendency as its loosely cohesive framework of Keynesian social democracy imploded in the 1970s, as a means of demonstrating its relative incoherence and fragmentation. The ‘crisis of social democracy’ revealed much more starkly its complex, heterogeneous character, irremediably ‘divided within itself’ over a range of critical political and policy themes and the basis of social democratic political philosophy itself. The article argues that it was its own wider political fragmentation and ideological introspection in the face of the ‘crisis’ of its historic ‘belief system’ which led to the fracture of Labour's ‘dominant coalition’ and the rupture of British social democracy. |
