David Cameron promises to lift lid on his time in Downing Street after former Prime Minister signs book deal

DAVID Cameron has promised to lift the lid on his time in Downing Street after the former Prime Minister signed a deal for his autobiography.

He will spend the next year writing the "frank" account, which will give an insight into family life at Number 10 as well as the inside track on his government.

Publisher HarperCollins has agreed to print the memoir, after Mr Cameron hired star literary agent Ed Victor, who has secured lucrative deals for Alastair Campbell and David Blunkett in the past.

The 50-year-old has said he will explain the decisions he made and will admit "what worked and what didn't" in the tome, which does not yet have a title.

As well as covering Brexit and the crushing defeat that brought his political career to a screeching end, it will also go over the Scottish independence vote and range across reforms to the economy, welfare and education.

The book will draw on over 50 hours-worth of audio tapes recorded with Times columnist Daniel Finkelstein, and Mr Cameron's controversial handling of foreign affairs, including the bombing of Libya, and the crucial vote he lost on Syria, will also be examined.

It will be published under the William Collins name, an imprint of HarperCollins, with an expected release date of 2018.

Mr Cameron said: "It was an immense privilege to lead the Conservative Party for more than a decade and the country for over six years as prime minister.

"I am looking forward to having the opportunity to explain the decisions I took and why I took them. I will be frank about what worked and what didn't."

Since stepping down from the Commons he has kept a low profile, and has been pictured leaving his new home in Chelsea taking his daughter on the school run.

He announced his first new job post-politics would be an unpaid role at the National Citizens Service Trust — the charity that implements his Big Society flagship policy.

But he is expected to have a lucrative career on the after-dinner circuit, and has already signed up to a give a speech to a US private equity firm founded by Mitt Romney.

Meanwhile his wife Samantha has been seen back at work amid rumours she is set to launch her own fashion label.

The 45-year-old registered a company called Samantha Cameron Studio Limited last week, and was pictured spending time at an office Kensington, west London.
