From The Times:
David Cameron poked fun at John Bercow, the Commons Speaker, in a speech to journalists yesterday.
The Prime Minister recounted an apocryphal encounter between Mr Bercow and Simon Burns, the Health Minister, who called the Speaker a “sanctimonious, stupid dwarf”.
Mr Cameron described Mr Burns persuading his driver to reverse into the Speaker’s car.
An angry Mr Bercow, who claims to be 5ft 7in, confronts the minister, saying: “I’m not happy.”
To which Mr Burns replies: “Well, which one are you then?”
