A protester has invaded the stage as Gordon Brown addressed the CitizensUK Meeting in London.
The Prime Minister have been speaking to delegates from faith groups gathered at the Central Methodist Hall in Westminster.
During his speech he was interrupted by a man who made his way to the front of the stage with a banner saying "NuKiller Power No".
He came within yards of the Prime Minister before being bundled to the floor by security and dragged from the stage.
Sky's Chief Political Correspondent Jon Craig was watching and said the Prime Minister looked "very startled" after the altercation.
Gordon Brown told the crowd: "I'm used to worse" and received cheers as he carried on with his speech.
