Former Oasis frontman Liam Gallagher yesterday launched an High Court lawsuit against his guitarist brother Noel.

Hothead Liam issued a libel writ over Noel's claim an Oasis gig was axed because the singer was hungover.

Liam said it was a slur on his professionalism and demanded a written apology.

When did not receive one, he decided to take action through the court system.

The brothers have been in constant conflict since Oasis split in 2009, with Liam recently calling Noel a "little bitch" for claiming he had been bullied out of the band.

Noel countered by saying Liam had "creepy" voice messages on his girlfriend's phone.

Then last month Noel claimed the band had no choice but to pull out of the 2009 V Festival in Chelmsford, Essex, because Liam had a hangover.

The official reason given at the time was Liam had laryngitis.

Yesterday, Liam issued a statement: "That is a lie and I want Oasis fans to know the truth.

"I was gutted when I couldn't play the gig because I didn't want to let the fans down. The truth is I had laryngitis, diagnosed by a doctor, preventing me performing that night."

He added: "There are many reasons why Oasis split. But it had nothing to do with my clothing range."

Noel, now a solo artist, will have to make an official response to the writ to the High Court. And if the pair remain at loggerheads they will have to argue it out before a judge.
