This paper has four main aims. Firstly, it identifies and compares the timescapes advanced and articulated by Britain’s two major political parties in the post-war period. Secondly, it accounts for differences between the two parties and identifies the dynamics which have driven change in their timescapes. Thirdly, it identifies how these timescapes served the political goals of each party’s leadership. Finally, the paper reflects upon how its analysis both corresponds to and challenges existing temporalisations of British politics.
