Junkie rocker Pete Doherty has been sent to jail for 14 weeks following his drug offences and failure to turn up on time for his probation hearings.

The 28-year-old singer has been ordered 14-week imprisonment at West London Magistrates' Court.

According to a court spokesman, the 'Babyshambles' frontman has been jailed for a "breach of time keeping, non-compliance of his order and using different drugs."

Judge Davinder Lachar had earlier given him a four-month suspended sentence in October, along with an 18-month supervision order and a 12-month drug rehabilitation order.

Doherty has also been asked to pay a 400 pounds fine for driving without insurance and a 75 pounds fine for having no MOT certificate

He has also been forced to postpone his gigs at the Royal Albert Hall and Glastonbury Festival, following his imprisonment.

"Unfortunately Peter has had to postpone his show at the Royal Albert Hall on April 26th," the Telegraph quoted a spokesman for EMI, as saying.

"The show is due to be rescheduled and all tickets will be valid for the new date once it has been announced.

"Peter was very much looking forward to the show and would like to offer his sincerest apologies to all his fans and all those concerned," the spokesman added.
