For a century, Britain's newspapers have been run by a handful of extraordinary men - the press barons. Andrew Neil tells the remarkable story of Britain's newspaper proprietors and their relationships with the Prime Ministers of the day. From Lord Northcliffe and Lloyd George, to Lord Beaverbrook and Winston Churchill, to Rupert Murdoch and Gordon Brown, it's a tale of power and intrigue at the very top, and the epic battles between Fleet Street and Downing Street.
