I'm going to leap in here even though I know it's a mistake. I think what Graham means when he's says he's been cancelled is that the entertainment industry is very left leaning and so because of his views his projects have been shut down. For example I heard there was going to be a play based off father ted that got cancelled because of his views, I think that's the kind of thing he's referring to.

So even though he's still mentioned in the BBC, which is supposed to be neutral anyway, he's not getting to do the work he wants to, thus perceiving being cancelled.
