British rock star Pete Doherty has been jailed for 14 weeks for breaching terms of his probation, his record label says.

The sentence, handed down at a west London court, forces 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.

Doherty, 29, has been in and out of court in recent months in connection with his well-publicised battle with drug abuse.

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 Moss. The pair are no longer together.

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