Marking the third centenary of the office of Prime Minister, this book tells its extraordinary story, explaining how and why it has endured longer than any other democratic political office in world history. Sir Anthony Seldon, historian of Number 10 Downing Street, explores the lives and careers, loves and scandals, successes and failures, of all our great Prime Ministers. From Robert Walpole and William Pitt the Younger, to Clement Attlee and Margaret Thatcher, Seldon discusses which of our Prime Ministers have been most effective and why. He reveals the changing relationship between the Monarchy and the office of the Prime Minister in intimate detail, describing how the increasing power of the Prime Minister in becoming leader of Britain coincided with the steadily falling influence of the Monarchy. This book celebrates the humanity and frailty, work and achievement, of these 55 remarkable individuals, who averted revolution and civil war, leading the country through times of peace, crisis and war.

‘A tremendous, magisterial book, informed and underpinned by brilliant historical and political insight. A triumph.’

William Boyd - author of Trio, Restless and Any Human Heart

‘Anthony Seldon enriches our understanding of what it takes to run Britain, with some intriguing ideas for improving the Premiership.’

Camilla Cavendish - former Head of No. 10 Policy Unit, and author of Extra Time: Ten Lessons for Living Longer Better

‘A brilliant, panoramic survey of the fifty-five individuals who have been prime minister since Robert Walpole - and their families too. The most moving sentence is right at the end. On the evening of David Cameron’s resignation, his daughter asks him at bedtime: ‘Daddy, when are we going back home?’ By then, you feel you know many of the holders of the office of prime minister intimately, how they changed it and it and how it changed them. A must read.’

Andrew Adonis - former transport minister, education minister and Head of No. 10 Policy Unit, and author of Ernest Bevin, Labour’s Churchill

‘Three hundred years of one of the world’s most difficult jobs is worth some reflection - and there is no better way to go about that than to read this excellent book. With a rich knowledge of our prime ministers and the eye of an expert historian, Anthony Seldon has produced a stimulating and enjoyable study of the unceasing development of their power and role. There is much here to inform everyone from the general reader to the political addict, and some important indicators of what the future may hold.’

William Hague - former Leader of the Opposition, First Secretary of State, Foreign Secretary, and Leader of the House of Commons

‘A fascinating review of the role of the prime minister and those who have filled it. How were they constrained, how did they change the role, and how did it change them and the country. Anthony Seldon also suggests some improvements including making No. 10 more streamlined, agile and diverse and ensuring that prime ministers and those around them understand the role. Reading this book would give them a good start.’

Jacqui Smith - former Home Secretary

‘Anthony Seldon has a brilliant ability to capture the humanity of prime ministers as well as their role in history which is why this fascinating account is so readable as well as authoritative. It is essential reading for anyone who wants to understand both how Downing Street works and the extraordinary characters of those who have lived there.’
