British Prime Minister David Cameron has been accused of putting his private part in a dead pig’s mouth when he was a university student at Oxford.
The allegation was published in a new biography - "Call Me Dave" - by politician Lord Ashcroft and journalist Isabel Oakeshott, The Daily Mail reports.
The authors reportedly cite a source who claimed that Mr Cameron "put a private part of his anatomy" into a dead pig's mouth during an initiation ceremony for the Oxford Dining Society, the "Piers Gaveston".
British Media has quoted Mr Ashcroft saying: "Perhaps it is a case of mistaken identity. Yet it is an elaborate story for an otherwise credible figure to invent.
"Furthermore, there are a number of accounts of pigs' heads at debauched parties in Cameron's day."
The book also alleged Mr Cameron was a member of the "Flam Club," which was a "dope-smoking group."
Mr Cameron has not yet publicly responded to the claims.
The hashtag #piggate is now trending worldwide on Twitter.
