In 1962 the American statesman Dean Acheson famously charged that Britain had lost an empire and failed to find a new role. Nearly 60 years later, the rebuke rings true again. Britain's postwar search for its place in the world has vexed prime ministers and government since the nation's great victory in 1945: the cost of winning the war was giving up the empire.

After the humiliation of Anthony Eden's Suez expedition, Britain seemed for a time to have found an answer. Clinging to its self-image as a great island nation, it would serve as America's best friend while acknowledging its geography by signing up to membership of the European Union.

It is an indispensable guide to how we arrived at the state we are in.
