James Graham on John Maynard Keynes

James Graham, the award-winning playwright whose work includes the TV dramas "Brexit: The Uncivil War" and "Quiz", tells Matthew Parris why he is inspired by the life and work of John Maynard Keynes. Keynes was not just the revolutionary economist who helped shape the course of post-war history. The programme explores his colourful love life and lifelong passion for the arts. Matthew and James are joined by Linda Yueh, economist and author of "The Great Economists: How Their Ideas Can Help Us Today". Producer: Chris Ledgard
