S3 E1 Jonn Elledge on history, borders and the British

To kick off Series 3, I speak to writer and journalist Jonn Elledge on his new book 'A History of the World in 47 Borders: The Stories Behind the Lines on Our Maps'. We delve into the stories you should know about but probably don't, the history that never happened, the optimistic stories and of course - how Britain looks at its history.
