ABSTRACTThis paper is about Marxist political economy and Critical Discourse Studies as a field of inquiry. It begins with a discussion of the traditional role of Marxist political economy in CDS, arguing that for the most part it has been limited and partial. It then considers an example of a serious attempt to carry out a Marxist political economy analysis of discourse in society – Claudia Ortu’s [2008. The denial of class struggle by British Governments in their anti-union discourse. Critical (...) Discourse Studies, 5, 289–301] analysis of the denial of class struggle and anti-union discourse in Britain in the period 1978–2007. This leads to a discussion of the author's recent research on material and discursive class warfare in contemporary Spain, focussing specifically on conflicts arising between a right-wing government defending the interests of the banks and elites and a grass-roots organisation defending the interests of the popular classes, in particular those who either have lost, or are in danger of losing, their homes due to mortgage default. The paper ends with some thoughts on the future of CDS, with or without a clear Marxist political economy base. (shrink)
