The Prime Minister used the phrase beloved of paranoid conspiracy theorists as he repeatedly claimed the Labor leader wanted to undo Brexit. “We’ve done Brexit and the pundits and the avengers are left plotting and plotting and biding their time,” Johnson said, before suggesting his legacy was under threat. He said: “Some people will say as I leave office that this is the end of Brexit… and the leader of the opposition and the deep state will prevail in his plot to bring us back into line with the EU as a prelude to the eventual RETURN. “ Challenging Tory MPs to stick to his hard Brexit deal, Mr Johnson added: “We on this side of the House are going to prove them wrong, aren’t we?” Last month Sir Keir promised not to return the UK to the EU’s single market or customs union, nor restore freedom of movement, as he set out his plan to “make Brexit work”. Mr Johnson pointed to Mr Starmer’s record against Brexit deals, claiming he had tried to “overturn the will of the people” – and would attempt to overturn Brexit again if he became prime minister. The outgoing Prime Minister said: “Have no doubt, if he ever came to power with the desperate coalition of the Lib Dems and Scottish nationalists, he would try to do it again at the drop of a hat.” Sir Keir hit back by accusing Johnson of indulging in pure fantasy when it came to his legacy. “The delusion never ends – what a relief for the country that they finally managed to sack him,” he said. The Labor leader added: “He has been forced to leave in disgrace, judged by his peers and colleagues as unworthy of his position and unfit for office.” Mr Johnson won cheers from Tory MPs when he boasted of his party’s 2019 election victory over Labour, claiming they had “sent the big blue ferret so high up their left leg that they couldn’t budge”. He also added that he believed Tory MPs would prove Sir Keir “absolutely wrong” about the prospect of a Labor election victory, adding that they would send the opposition leader “into orbit”. MPs will hold a vote of confidence in the government on Monday night at around 10pm, amid renewed calls from the opposition for Johnson to step down immediately and hand himself over to a civil servant. Former Labor Secretary Dame Margaret Hodge said: “This debate is essential to stop Trump’s dangerous attack on everything we value in our British democracy.” But Tory MP Sir Edward Leigh said he “thoroughly regrets the departure of this prime minister and I remain totally loyal to him to the end… And I think we will ask ourselves, what have we done?” “Where is the sense of goodness? Or magnanimity? Why do we have to throw these insults?’ he added of Sir Keir’s conviction. The loyalist said it wasn’t as if Johnson was “the worst kind of mass murderer and criminal in political history.”
