Corbynites are nuts. At the moment they're outraged because the BBC managed to get one of the MPs to resign on the Daily Politics, it appears Kuenssberg heard of his impending resignation and got him to do it on their show.
This is normal considered a 'scoop' but actually it's a gross injustice from the BBC it seems. The BBC is now conspiring with the right-wing Labourites to damage Corbyn and so his loyal army has mobilized and done what they do best. A change.org petition:
