You couldn't move for them in the 70s, but without resorting to Wikipedia, I would be hard-pressed to name a single successful one right now.
This stems from the ongoing Andrew Lawrence / Nigel Farage / Frankie Boyle spat:

Andrew Lawrence (a comedian whose work I am not familiar with) states:
The reason there are no right-leaning comics in this country is because whenever one has the balls to stand-up, they become the target of a witch-hunt. Where there should be balance, there is, terrifyingly, censorship.
Can there REALLY be some sort of conspiracy to keep right wing comedians off of all UK tv channels? I could have believed that back when we only had four channels - but right now, we have 480 (or more)!
Could it be that 'right wing humour' is the world's biggest oxymoron?
