This exploration of one of the most concentrated immigrant communities in Britain combines a fascinating narrative history, an original theoretical analysis of the evolving relationship between progressive left politics and ethnic minorities, and an incisive critique of political multiculturalism. It recounts and analyses the experiences of many of those who took part in over six decades of political history that range over secular nationalism, trade unionism, black radicalism, mainstream local politics, Islamism and the rise and fall of the Respect Coalition. Through this Bengali case study and examples from wider immigrant politics, it traces the development and adoption of the concepts of popular frontism, revolutionary stages theory and identity politics. It demonstrates how these theories and tactics have cut across class-based organisation and acted as an impediment to addressing socio-economic inequality; and it argues for a left materialist alternative. It will appeal equally to sociologists, political activists and local historians. -- .
