His dodgy punnery is fast become a staple of prime minister's questions and this Karl Marx jibe at Jeremy Corbyn is pretty much the worst yet.
Quizzed on NHS waiting lists and deficits by Corbyn, the Prime Minister spat the following scripted joke:
"What is going up in the NHS is the number of treatments, is the number of successful outcomes. And if he wants to know who is heading for a winter crisis, I would predict that it's the Labour Party who is heading for a winter crisis.
Look at his appointments: his media adviser is a Stalinist, his new policy adviser is a Trotskyist; and his economic adviser is a Communist. If he's trying to move the Labour Party to the left, I'd give him full Marx."
Before being totally owned by Corbyn’s excellent ‘You're-an-idiot’ face seen above.
