Sometimes political balance is important to the BBC

There's a fascinating article in The Times today, page 5 of the print edition. 

Apparently Barry Humphries wanted to tell a joke about Jeremy Corbyn when he was to appear on Michael MacIntyre's Christmas show. He was told that for balance he'd 'also have to say something about Mr Cameron.'

Oddly this political balance doesn't seem to apply to the majority of BBC topical news quizzes and panel shows where lampooning Conservatives is de rigeur, Labour less so. And as for UKIP and Donald Trump, well the BBC don't even pretend to be impartial there.
