Sir Anthony Seldon is the acknowledged national authority on all matters to do with Number 10 and prime ministers. His first book on a prime minister, Churchill's Indian Summer: The Conservative Government, 1951–55 (1981), was published forty years ago, and since then he has written or edited many books, including the definitive insider accounts of the last six prime ministers. He has been the honorary historian at Number 10 Downing Street, chair of the National Archives Trust, and has interviewed virtually all senior figures who have worked in Number 10 in the last fifty years. His BBC Radio 4 series 'The Prime Minister at 300' was broadcast on the 300th anniversary of the office in April 2021.
