David Cameron famously bought a £25,000 shepherd’s hut to provide him with a peaceful spot in his Oxfordshire garden to write his memoirs.

However it does not appear to have helped him finish his book, with the publication of his story of life in 10 Downing Street now "most likely" delayed until next year.

Mr Cameron has a £800,000 contract with William Collins, part of the HarperCollins Publishers empire, to write his account of his time in office. The autobiography had been expected to be published this Autumn.

Last week the former Prime Minister eve admitted in a CNN interview that he had to “get on with it” when asked how the book was going.

However sources close to Mr Cameron have told The Daily Telegraph that the publication date is still to be confirmed but is now “most likely next year”.
