Camilla Parker Bowles's son supplied pals with drugs while he studied at Oxford University, claim his ex-college friends.

Prince Charles's godson Tom Parker Bowles, 24, bought cocaine, ecstasy and cannabis for himself and friends during his three years at Worcester College.

One source told a Sunday paper: "I would put an order in and Tom would come back with what I wanted."

During his first year, he was arrested for possession of ecstasy tablets and cannabis after being searched leaving a south London nightclub. He claimed the drugs were for personal use and escaped with a caution.

Mr Parker Bowles confessed to taking cocaine last week and has since promised his mother and Prince Charles he will stay clean.

Another friend said: "Tom was well known as a heavy drug user and somebody who could get you drugs if you wanted them. He was quite open about taking drugs and when he went to buy them from dealers, he would often get them for his friends too.

"He seemed to be able to get pretty much anything I needed - cocaine, cannabis, Ecstasy. He certainly liked to party and drugs and alcohol were a very important part of his life. They were an important part of a lot of people's lives at Oxford and from what I understand, they still are." Parker Bowles became a 'baron' of the secretive society, Assassins, known for its bizarre parties and drinking sessions.

He was a founder member of the Oxford 'brat-pack' which included Lord Frederick Windsor, son of Prince and Princess Michael of Kent, Piers Adam, founder of fashionable K-Bar chain, and Peregrine Hood, son of 4th Viscount Bridport, who is now described as 'out of control'.

Prince Charles is said to be 'fraught with worry' that William is now seen out with the group and has asked his son directly if he has ever taken drugs.

The Marquess of Blanford, heir to Blenheim Palace at Woodstock, admitted being addicted to cocaine for five years, and said: "I know to my own personal cost that drugs ruin your health, disturb your mind, cost all your money and hurt family and friends. "Tom might not know it yet. He might be so deeply in danger that he thinks all this is funny, but he is now a moving target. I hope this is the shock he needs to turn his life around."
