British rocker Pete Doherty jailed for 14 weeks

British rock star Pete Doherty was jailed yesterday for 14 weeks for breaching terms of his probation, his record label said.

The sentence, handed down at a west London court, forces Mr Doherty to reschedule a performance at the Royal Albert Hall scheduled for April 26.

His appearance at Britain's high-profile Glastonbury festival at the end of June is also in doubt.

Adrian Hunter, Mr Doherty's manager, said there were "numerous reasons" the singer/songwriter had been jailed. "One of them was his late coming at probation hearings," he said. Mr Doherty, 29, has been in and out of court in recent months in connection with his well-publicised battle with drug abuse.

At a court hearing in October he admitted a string of drug and driving offences, but escaped jail when he was handed a suspended four-month prison term.

Mr Doherty, known for his work with The Libertines and the band Babyshambles, pleaded guilty to driving illegally while in possession of crack cocaine, heroin, ketamine and cannabis. He also hit the headlines over his relationship with supermodel Kate Moss.

Shortly afterwards, he publicly apologised after being filmed taking heroin, having just told a music magazine that he was beating his addiction. He called that relapse a "stupid, stupid action for which I feel only shame".

The singer has been a favourite of Britain's tabloid press, particularly during his on-again off-again relationship with Ms Moss. The pair are no longer together.

Asked whether Mr Doherty would appeal against the court's decision, Mr Hunter said: "That is in the hands of the lawyers at the moment. I can't comment on that".
