A general election is due in the UK within the next three months. It comes against a backdrop which - on the face of it - could hardly be worse for Gordon Brown, the British prime minister. In an explosive new book, he is revealed as ill-tempered and difficult. But his party is actually going up in the polls. Hearing that their prime minister is a bit of a bully, voters seem to like him more. Sir David is joined by the author of the book they are all talking about, Andrew Rawnsley.
