Anthony Seldon ranked Winston Churchill as the greatest British prime minister in his recent Daily Telegraph article, “The ten greatest prime ministers of all time – and the five worst.” Seldon, the author of Churchill’s Indian Summer: The Conservative Government, 1951-55 and several other books, credited Churchill with providing “uniquely-strong leadership for Britain in 1940 at the time of its greatest peril in the 300 years that Britain has been governed by Prime Ministers.” Churchill was followed in the rankings by William Pitt the Younger and William Gladstone, while the three considered the worst prime ministers were Lord North, Neville Chamberlain, and Anthony Eden.
