In a special live edition recorded at the Wilderness Festival, David talks to BBC Food Programme presenter Sheila Dillon and best-selling food writer Jack Monroe about austerity, Brexit and the politics of how people eat. What is gained and what is lost when politician talk about food as a matter of personal choice? Just how powerful are the big food corporations? And is it really possible for Britain to take back control of its food supply? With some lively questions from the audience.
