PM Says He's 'Too Busy' To Sue Lord Ashcroft

David Cameron has told Sky News he won't be taking legal action against Lord Ashcroft over his controversial biography because he is "too busy running the country". But in his first television interview on the subject, the Prime Minister also hit out at the former party donor's book saying people would "see right through it". The book makes a number of controversial claims including an allegation that while at university the Prime Minister took part in a bizarre student ritual involving a dead pig.
