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.

The shortest-serving prime minister in history. The first former leader to lose their seat since 1935. An inside look at how it all went so wrong.

Liz Truss's disastrous premiership was the shortest and most chaotic in British history. In the space of just 49 days, Truss witnessed the death of the longest-reigning monarch, attempted to remould the economy, triggered a collapse in the value of Sterling and was forced on a series of embarrassing U-turns that ultimately led to her resignation. The aftershocks of her time in office are still felt today. How did she blow her opportunity so spectacularly?

Based on exclusive interviews with key aides, allies and insiders, and focusing on the critical steps that led to her demise, this gripping behind-the-scenes work of contemporary history gives the definitive account of Truss's premiership.
