In 2013, Nigel Farage described freedom of speech as one of "the absolute fundamentals of free western society", adding "we fought two world wars to defend these very things".
He's also a fan of jokes. In the past he has been keen to gloss over offence caused by his party by claiming members were just joking. In fact it has become something a theme for UKIP to suggest the rest of the country doesn't know how to take a joke.
So imagine the surprise when it was reported that UKIP had gone to the police over a pretty throwaway comment about the party's leader on comedy panel show Have I Got News For You.
Kent Police are understandably having none of it. But UKIP isn't leaving matters there. According to ITV News:
"A Ukip official said they planned to pursue the matter with officers from Scotland Yard, adding the party is "now at war with the BBC"."
Meanwhile, the BBC was left to point out the obvious:
"Have I Got News for You regularly make jokes at the expense of politicians of all parties."
