A spokesperson for UK Prime Minister David Cameron says they won't dignify recent allegations made about his time as a university student with a response.
A new book alleges Cameron participated in a bizarre initiation ritual with a pig, and also took drugs.
The book was written by a former ally-turned-political-enemy of Cameron's, and extracts were published by the Daily Mail.
The politician claimed the Oxford University initiation ceremony involved a dead pig and that Cameron "inserted a private part of his anatomy into the animal's mouth". The hashtag #Piggate quickly topped Twitter trending in Britain, with users making many pig-related puns.
