John Lydon has hit out at Green Day calling them â€œplonkâ€ and accusing them of stealing the term â€˜punkâ€™.
The former Sex Pistols front man says the US trio are a watered down version of the true punk ethos according to contactmusic.
He said: "Don't try and tell me Green Day are punk. They're not, they're plonk and they're bandwagoning on something they didn't come up with themselves. I think they are phony."
He added on the subject of the Sex Pistols battle with the establishment: "The government's against you, the police are on you. So there we are fending off all that and it pisses me off that years later a wank outfit like Green Day hop in and nick all that and attach it to themselves.â€
"They didn't earn their wings to do that and if they were true punk they wouldn't look anything like they do."
