In an interview with Q Magazine, Liam claimed that Noel’s return to the band is being blocked by his wife, Sara MacDonald.
Noel, 50, previously told the same magazine he had no interest in getting Oasis back together, saying it would “kill him as a person”.
Liam, 45, said: “He’s desperate to get Oasis back but he knows he’s crossed that bridge.
“And he’s not allowed to, his missus (Sara MacDonald) won’t let him now, cos she’s another one.”
He added: “I know for a fact, deep down, he wants to be playing stadiums… You can only play stadiums when I’m there.
“I don’t think our kid’s got it in him anymore, anyway. It seems to me like he’s playing to the snobs and the world and the toffs.”
He said his brother “is not a frontman” and added: “I’m not a songwriter. He’s not meant to be in the middle of that f****** stage. I’m meant to be centre-stage and no-one can touch me.”
Oasis were one of the biggest bands in the UK from their breakthrough with Definitely Maybe in 1994, until they split in 2009.
Noel left the band and formed Noel Gallagher’s High Flying Birds, while Liam continued with the remaining members as Beady Eye.
The brothers have a long history of spats. When Noel said he wanted to “bury the parka monkeys” with his new album, Liam replied with: “He’s f****** with a generation there, man. I’d rather be a parka monkey than a f****** Givenchy f******’ Bond Street … wearing clown or whatever he is.
“Parkas, bring it on.”
Just before Christmas, the pair seemed to have buried the hatchet, with Liam tweeted “Happy Christmas” to Noel’s team and suggesting he had “reached out” to him.
In the Q interview, Liam also said he wants to play three Oasis albums, Definitely Maybe, Morning Glory and Be Here Now, saying: “F*** the rest. No-one cares after that… I want to give people what they want and I want to give me what I want.”
