The Darkness frontman Justin Hawkins's proudest moment is calling British prime minister Tony Blair a "murderer".

The I BELIEVE IN A THING CALLED LOVE hitmaker was disgusted by the leader's decision to go to war with Iraq - even though Blair is a huge fan of the glam rockers.

Hawkins says, "He is absolutely loathsome.

"Blair did used to be a fan. His son came to one of our concerts. But then I called him a murderer during the Iraq war - one of my proudest moments - and EUAN hasn't been seen since.

"I can't stand the guy because he's a fraud."
