Ian Parker's Mapping the English Left through Film: Twenty Five Uneasy Pieces is a block-buster of a book, mercilessly unpicking the cinematic narratives that infuse twenty-five organisations. Key elements of plot and production are used to tell the story of purges and splits and cult-favourites in this innovative history of Trotskyist groups in England. This is the place where revolutionary Marxism goes to the movies.

Ian Parker is Professor of Psychology in the Discourse Unit at Manchester Metropolitan University, where he is managing editor of 'Annual Review of Critical Psychology'.' He is a member of Psychology Politics Resistance, which is now part of the Asylum collective. He has produced seventeen books, including The Crisis in Modern Social Psychology, and how to end it (1989), Qualitative Psychology: Introducing Radical Research (2005) and Slavoj Zizek: A Critical Introduction (Pluto Press, 2004).
