Boris Johnson is under mounting pressure to quit the fractious race for Prime Minister after a leading Tory said he is a "guaranteed disaster" who will "implode".
Steve Baker, an influential right-wing Brexiteer who backed Mr Johnson in 2019 and Liz Truss this year, launched a blistering attack on the former premier's comeback bid and backed Rishi Sunak instead.
Speaking on Sky News, Mr Baker said Mr Johnson "is a guaranteed nailed-on failure” and "he’s bound to implode, taking the whole government down with him”.
