The culture secretary – a staunch Boris Johnson supporter – retweeted an image from a film of the outgoing prime minister’s face being imposed on Julius Caesar, with Mr Sunak behind him. Greg Hunts, the business minister who is backing Mr Sunak in the No 10 race, told Sky News on Sunday that he was “certain Liz Truss will renounce this kind of behaviour”, which he described as “disgusting”. “Look, it’s not even a year since Sir David Amess was stabbed in his election intervention in Southend, so I think this is very, very bad taste, even dangerous,” he added. Senior Tory MP Simon Hoare also shared a post on Twitter urging Ms Dorries to delete the retweet, stressing: “We shouldn’t treat our politics or our discourse like this.” MPs condemned Nadine Dorries for sharing a tweet (PA) SNP MP Stewart McDonald added: “Nadine Dorries — currently Secretary of State — is completely unfit for any public office.” The row arose as Mrs Dorris also used a newspaper article to admit she “perhaps went slightly over the top” last week when she mocked the former chancellor for wearing £490 Prada shoes and expensive suits. “I wanted to highlight Rishi’s misguided style to warn Tory members not to be swayed by appearances as happened to many of us who served with the chancellor in cabinet,” he wrote. He then used the same article in the Mail on Sunday to criticize Mr Sunak’s decision to quit the government, saying he “made Michael Gove’s betrayal of Boris Johnson during the 2016 leadership campaign look like an amateur act rehearsal for the role in a village play. “. Welsh Secretary Sir Robert Buckland, another supporter of Mr Sunak, also denounced Ms Dorries’ behaviour. “I think this kind of imagery and narrative is not just inflammatory, it’s wrong,” he told BBC Radio Wales. “I think it’s time those who think a controversy about Prada shoes or earrings is more important, for example, should hang their necks and let people talk about the issues rather than the personality.” Former Northern Ireland secretary Brandon Lewis, who has thrown his weight behind Ms Truss in the leadership contest, told Sky News: “It’s certainly not something I would put on Twitter.” He added: “Nadine is known for having strong opinions on things. Nadine speaks for herself, she is very special about it. But that’s not a position Liz would take.”
