The Treasury is one of Britain’s oldest, most powerful and secretive institutions, one that has played a central role in shaping the country's economic system. But all too often it has escaped public scrutiny when it comes to investigating the ups and downs of the UK economy.

When portrayed, it is usually as a bedrock of government stability in times of crisis, repeatedly rescuing the nation’s finances from the hands of posturing politicians and the combustions of world financial markets. However, there is another side to the story. In between the highs there have been many lows, from botched privatizations to dubious private finance initiatives, from failing to spot the great financial crisis to facilitating ever-growing inequalities.

Davis’s book goes behind the scenes to offer an inside history of the Treasury, in the words of the chancellors, advisors and civil servants themselves. It shows the shortcomings as well as the successes, the personalities and the thinking which have shaped Britain’s economy since the mid-1970s. Based on interviews with over fifty key figures, it offers a fascinating, alternative insight on how and why the UK economy came to function as it does today, and why reform is long overdue.
