After the largest strike in the sector for a generation, we talk to Stephen Toope, Vice-Chancellor of Cambridge University, about the politics of higher education. How did the issue of pensions become so politically charged? What are the long-term consequences of treating students as consumers? How should universities respond to the challenge of Brexit? Plus we return to the question of why having a university degree is now one of the main dividing lines in contemporary politics. With Helen Thompson and Chris Brooke.
