David Willetts MP and the writer and philosopher Roger Scruton discuss the best way to foster knowledge in schools and universities and whether politicians have become too professionalised. In an age when many politicians have never had other jobs, are we better off with representatives who have specialist knowledge from careers forged outside Westminster? The conversation is chaired by Anne McElvoy and was recorded in front of an audience at the Free Thinking Festival at Sage, Gateshead.
