The Libertines have decided to continue without singer and guitarist Pete Doherty, who has been battling recurring drug-addiction problems.

The band's official statement said: "It is with regret that The Libertines announce they are to continue without singer and guitarist Peter Doherty due to his well-known addiction problems, specifically with crack cocaine and heroin."

According to NME.com, Band member Carl Barat said: "Peter is and always will be a Libertine and when he cleans up from his addictions he will be immediately welcomed back into the band.

"This decision is made with love and with no disregard to Peter and his problems. The other members of the band - Gary, John and myself - have come to this conclusion after three recent failed rehab attempts, all of which The Libertines have funded."

"Peter's erratic mental state worries us greatly and having him on tour would only compound his problems. We aim to complete all existing tour commitments without him," it added.

The Libertines cancelled two festival appearances in June because Doherty was ill.

The band are due to appear at the OXEGEN festival on Sunday 11 July and their new album will be released on 30 August. Doherty will not be a part of its promotional campaign.

In related Libertine news, Doherty appeared briefly at Thames Magistrates Court in London yesterday to plea not guilty to possession of an offensive weapon.

This charge stems from when he was arrested two weeks ago and he will return to the court for a preliminary hearing on 10 August.
