DAVID CAMERON once placed his private parts in a dead pig’s mouth, it was claimed last night.
He was in a university society which indulged in “bizarre rituals and sexual excess”, according to a new political autobiography.
The book, Call Me Dave, is co-authored by billionaire former Tory donor Lord Ashcroft and charts the PM’s life from Eton and Oxford University to No10.
One source in the book claimed the future PM was being initiated into the Piers Gaveston Society dining club when he “put a private part of his anatomy” into a pig’s mouth.
The insider — now also am MP — claimed to have seen photographic evidence of the incident. The pig’s head was resting on a pal’s lap at the time, the book claims.
Mr Cameron was also a member of another notorious drinking society, the Bullingdon Club, whose members loved to trash restuarants while wearing garish tails and waistcoats costing thousands of pounds.
It is alleged Mr Cameron also “slept with all the good-looking girls from college”.
One friend from the time, James Delingpole, tells how he smoked cannabis joints with the PM at university in the 1980s while listening to chart-toppers Supertramp.
The book, published next month, even alleges that cocaine was allowed to “circulate” around Mr Cameron and wife Sam’s house in Notting Hill, West London.
Lynton Crosby, the Tory’s election guru, is also said to have privately described the PM as a “tosser” and a “posh ****”.
Ex-party deputy chairman Lord Ashcroft, who donated £8million to the Tories, fell out with Mr Cameron after failing to get a powerful job.
This book is seen as his long-awaited revenge on the PM, who last year was pictured holding a pig in his Oxfordshire constituency.
The Prime Minister’s official spokeswoman said today: “I am not intending to dignify this book by offering any comment.
“He (Lord Ashcroft) has set out his reasons for writing it. The Prime Minister is focused on getting on with the job of running the country.”
Lord Ashcroft, who admits a “beef” with Mr Camerron, insisted his book is “not about settling old scores”.
Co-author Isabel Oakeshott, former political editor of the Sunday Times, also denied that was the motivation.
She said: “If this was just a revenge job, Lord Ashcroft and I could have published it before the election.”
