We talk about one of the central questions of British politics: what does Jeremy Corbyn really want? In the week he's been forced to answer questions about what he did in the Cold War, we ask where his past connects to his present and how long he can maintain his delicate balancing act on Europe. Plus we discuss his attack on the press barons who are attacking him: where does power now lie in the new media landscape? With Helen Thompson and Chris Brooke.
