Former Prime Minister David Cameron has signed a deal with a leading publisher to write a "frank" account of his time in Number 10.

He will spend the next year penning his memoirs of his time inside Downing Street.

The book will chart political issues as well as his personal life with his wife, Samantha, and their three children.

Publisher Harper Collins has won the rights for the ex-Prime Minister's autobiography and it hopes to publish the work in 2018 - in the middle of the UK Government's negotiations with the EU.

It is expected to track Cameron's involvement in both the Scottish independence referendum and Brexit, which ultimately led to his downfall as Prime Minister.

His opponent in the 2014 independence referendum, Alex Salmond, has already published his memoirs.

The book will also deal with subjects such as his decision to bomb Muammar Gaddafi's forces in Libya as well his backing for military intervention in Syria, which the House of Commons initially rejected.

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."
