However in this matter he is one step behind his rival Boris Johnson.
Two years ago during Mayor's Questions he said of London Assembly Member John Biggs:
"He keeps up a constant babble like he is a Tourettes syndrome fellow. He is like an old chap on a park bench rambling. I do not mind. We have to put up with it. It is care in the community!"
His comments were greeted with loud guffaws from Tory London Assembly Members, as they were when he repeated them almost word for word several months later:
"In spite of old care in the community here [gestures to John Biggs AM] with Tourettes and his constant barracking, I think we run a very harmonious operation."
David Cameron has swiftly apologised for his offensive comments. Two years on, there's little sign that Boris Johnson will ever do the same.
