Kilroy Silk was pulled for being a racist and refusing to apologise ... ideal UKIP fodder ...
I think it was an article about Arabs in the Sunday Express, wasn't it? Not condoning or justifying his views in any way at all, but IIRC, it was more arrogant/dismissive/colonial-type racism (still disgraceful) rather than intrinsically hateful, FWIW. He never seemed to be a particularly nice man, but his programme worked well.
Maybe they could bring it back but with a different host, don't know who, though. Nobody too nice - that wouldn't work. Can you imagine if they gave it to Biggins to do? They'd have such hard-hitting, controversial topics as 'Are unicorns lovely?' It would end with group hugs and confetti and everybody agreeing that everybody there is simply fabulous, regardless of their opinions 
Richard Madeley would be good - all the same 'embarrassing uncle' as Kilroy but without the unpalatable views
Otherwise, Anne Diamond would do a sterling job, as she does when she covers for Jeremy Vine. No-nonsense but charming with it.
