Dillon was appointed as the editor of The Mail on Sunday in late 2021 when Ted Verity was promoted to become editor of its sister paper, the Daily Mail, after Geordie Greig left the post.[1][2] His appointment was not announced at the time, and Dillon is known for never having given a press interview and not having any profile on social media.[1]
In April 2022, he faced criticism over the newspaper's allegations that the deputy leader of the Opposition, Angela Rayner, had tried to distract Boris Johnson in the House of Commons by crossing and uncrossing her legs. The Independent Press Standards Organisation reported that it had received 5,500 complaints about the article and was exploring possible breaches of its code of practice.[3] The speaker of the House, Lindsay Hoyle, asked Dillon to attend a meeting to discuss the report. Dillon initially agreed to meet but later refused, saying that journalists should not "have to take instruction from officials of the House of Commons, however august they may be, on what they can report and not report."[4]
