Roy Hattersley argues in his new book, The Edwardians, that to regard the first decades of the 20th century as "a long and golden sunlit afternoon" is to confuse the benevolent self-indulgence of King Edward VII with the radical period to which he gave his name.
Hattersley talks to Philip Dodd about how the Edwardians ushered in modern Britain, revolutionising its politics, literature, science and arts. Producer: Thomas Morris
