Brillo does quite a good job, although I'm very disappointed he didn't immolate Corbyn before the last election. The ammo was there and it was a disservice to the electorate that he didn't.
In my view, the BBC's bias is as much about what it doesn't report at all. Take Brexit - I know there has been bad news, but good news is either not reported or reported as "despite brexit".
The implication being from the BBC that brexit is bad and that it is surprising that anything good can happen while we're leaving. That isn't neutrality. It's well documented and outrageous.
You are unlikely to hear the story on BBC news tonight about Corbyn's and Momentum's support for Slobodan Milosevic, which has been reported elsewhere this morning.
