A new biography claims Britain's Prime Minister David Cameron once put a "private part of his anatomy" into a dead pig's mouth.
According to the Daily Mail Mr Cameron carried out the act as a student at Oxford University during a bizarre initiation ritual.
A distinguished Oxford contemporary claims Mr Cameron took part in the ritual during an event organised by the Piers Gaveston Society, a dining club at Oxford.
The source, who himself is now an MP, first made the allegation in June 2014 and has since repeated them. He even claims photographic evidence of the alleged act exists.

The shocking allegation is featured in Call Me Dave: The Unauthorised Biography, written by Michael Ashcroft.
The book also claims Mr Cameron was part of a "dope smoking group" called the Flam Club.
