A good comment. Comedians probably usually slip under the radar because of the more obvious bias in the reporting.
It is notable that the panel shows seem to be always left wing. I am sure Boris is only invited onto Have I got News For you because the others can poke fun at him. Whether Boris turns this to his advantage or not as he possibly intends I am not sure. Is he treated as seriously as a politician as he would like? Possibly the trade off has worked because he is now touted as the next Tory leader.... but that's another subject.
Actually, one of the victims here would seem to be comedy itself because so many of these "comedians" are actually, from my own preferences, rather less than funny.
