Ananova:

The Libertines are to play their scheduled festival dates in July - but without co-frontman Pete Doherty.

NME.com reports the rest of the band came to the decision "with regret" to play the dates without Doherty.

A statement reads: "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."

Carl Barat added: "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."

The Libertines' second album is now complete, and set for release on August 30. It was recorded with Doherty in April and May, before his health problems escalated.

The band will be appearing at T in the Park on July 10, at the Oxygen Festival in Dublin on July 11 and at the Reading and Leeds Festivals at the end of August.
