The editor of The Mail on Sunday has refused to attend a meeting with Commons Speaker Sir Lindsay Holyle over the paper's controversial report about Anglea Rayner.
Sir Lindsay told MPs on Monday he had arranged a meeting with David Dillion following an outcry over claims the Labour deputy leader crossed and uncrossed her legs during Prime Minister's Questions to distract Boris Johnson.
In his response to the Speaker, published in the Daily Mail, Mr Dillon said he would not be attending as journalists should "not take instruction from officials of the House of Commons, however august they may be".
