David Cameron was Conservative Party leader during the largest financial crash in living memory. The Arab Spring and the Eurozone crisis both started during his first year as prime minister. The backdrop to his time in office included the advent of ISIS, surging migration and a rapidly changing EU.

Here he talks about how he confronted those challenges, from modernising a party that had suffered three successive electoral defeats to forming the first coalition government for seventy years. He sets out how he helped turn around Britain's economy, implementing a modern, compassionate agenda that included education and welfare reform, the legalisation of gay marriage, the referendum on Scottish independence and world-leading environmental policies.

David Cameron is searingly honest about the key players from his time in politics. And he is frank about himself – the things he got right and the things he got wrong. He opens up about family life too, including the tragic loss of his eldest son.

We learn why he kept Britain's promise on overseas aid spending and what it was like to commit British troops to conflicts in Libya, Iraq and Syria. He sets out how he won the first outright Conservative majority in nearly a quarter of a century, and describes the events leading up to the EU referendum, the renegotiation, the campaign – and his thoughts on it all today.

It is the most compelling record yet of what it's like to lead in modern times and to live behind the most famous door in the world.
