Liam Gallagher has vowed that an Oasis reunion concert to raise funds for the NHS will go ahead - "with or without" his brother Noel.
On Tuesday, the singer had set out a "demand" for the band to reform - adding that he was "sick of pleading" for the reunion to happen.
With his brother yet to respond, Liam Gallagher wrote on Thursday: "Wanna clear a few things up.
"Oasis gig for NHS charity as in all money raised goes to NHS not to me will happen with or without Noel Gallagher.
"It may not be the same but trust me it'll still blow your knickers off."

Oasis split acrimoniously in 2009 following a backstage brawl at a festival in Paris.
Liam and Noel have been locked in a war of words ever since.
Noel has previously described his brother as a "moron" - telling the Big Issue magazine that each and every one of Liam's tweets is a "nail in the coffin" for hopes that Oasis will reform.
