Lord Ashcroft, who donated millions to the party before falling out with Cameron, has co-authored 'Call Me Dave,' which makes a series of damming claims about the student days of Cameron.
    
The book claims that Cameron smoked marijuana and took part in bizarre initiation ceremony as part of a university society, called the Piers Gaveston Society.
    
However, sources close to the British Prime Minister have denied that he was ever a member of the club in question during his time at the Oxford University.
    
"I am not intending to dignify this book by offering any comment. He (Ashcroft) has set out his reasons for writing it. The prime minister is focused on getting on with the job of running the country," Cameron's Spokesperson said.
    
The book, co-written by journalist Isabel Oakeshott, is set for official release by the end of this month.
