In a 2004 article in The Guardian, Bragg was quoted as saying:

The British National Party would probably make it [into a parliament elected by proportional representation], too. It would shine a torch into the dirty little corner where the BNP defecate on our democracy, and that would be much more powerful than duffing them up in the street — which I'm also in favour of.

Where's the irony? No 'political' violence here, just plain vigilanti-ism.
