I read on jailhouse lawyer's blog that the broadcaster Nicky Campbell called someone a fascist, but later apologised. I should think so. The BBC term is "far right activist". Fascist, like extremist, can be used at the BBC when referring to left wing organisations, but never of right wingers, fascist or otherwise. I expect Mr. Campbell will be on a warning for this gaffe.
Still, no smoke without fire, eh?
