“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.”

UPDATE:  Not the full Marx after all:

Communism. Trotskyism. Stalinism all getting a look in at #PMQs. Leninists everywhere feeling left out
