David Cameron interrupted reading a letter from a former Labour MP to tell a member of the House: 'Calm down, dear'.
The prime minister had to break off twice more in his reply at PMQs, and the Speaker also reprimanded MPs about the noise in the House of Commons.
But members of the public later wrote in to the BBC's Daily Politics to say they were not impressed with the PM's choice of language towards Shadow chief secretary to the Treasury Angela Eagle, leaving him facing calls to apologise.
