Boris Johnson gave David Cameron a major political headache today after he spoke publicly of taking cocaine and cannabis as a teenager.
The Tory mayoral candidate answered a question about taking cocaine by saying "that was when I was 19", then discussed using cannabis.
It is the fullest discussion of drug use yet by the Henley MP and will open up Mr Cameron to fresh questions about his past.
The Tory leader, who was at Oxford with Mr Johnson, said in 2004 he had had the "normal student experience". He has also failed to deny claims in a biography that he had come close to being expelled for using cannabis at Eton.
Mr Johnson's drug past emerged today in a Marie Claire magazine interview by writer Janet Street-Porter.
Tut,tut......Just before the Mayoral elections too..........
