Regardless of which party is in power.
The fact is that the Conservatives have held power in some form for ages, so naturally comedians and panel shows are going to target them as they are in power.
Blair got targeted. Corbyn got targeted. Clinton, Bush, Trump and Obama got targeted.
I have heard a 'right wing comedian' on The News Quiz. He was talking about immigration I think. It's rare to hear them on such shows as 'apparently they aren't very funny' . Maybe there should be a quota...just like for women on such shows.
No doubt if the Conservatives lose the next election, then whoever is in power will be at the receiving end of comedy.
For the moment, Johnson is providing ammunition for satirists.
