Bad blood between the brothers has made headlines ever since Oasis burst to fame in 1994 with debut album Definitely Maybe.
When Noel left the band in 2009 he said it was because he couldn’t work “a day longer” with his brother.
Liam is disputing comments Noel made last month alleging that Liam pulled out of the 2009
Liam said in a statement he wants an apology and for Oasis fans “to know the truth” about what happened – laryngitis prevented him from performing the gig.
He also took issue with his brother’s claim that “the demise of Oasis followed a massive row in which he claimed I demanded to advertise my clothing range Pretty Green in the Oasis tour program.”
“The truth is there was no such discussion or row between us. There are many reasons why Oasis split. But it had nothing to do with my clothing range.”
“This is not about money,” he added. “All I want is a full apology from Noel.”
Liam Gallagher’s spokesman confirmed the singer had issued a writ at the High Court in London against his brother.
Representatives of Noel Gallagher declined to comment.
