Boris Johnson’s hopes of a return to Downing Street were today dealt a severe blow as influential Eurosceptic Steve Baker came out for rival Rishi Sunak, warning that victory for the former PM would be “a guaranteed disaster”.The Northern Ireland minister told Sky News that a second Johnson premiership would “collapse” within months as Tory MPs would not be willing to vote to save him from an inquiry into alleged Partygate lies.Mr Baker said it would be for the best if Mr Johnson did “something big and statesmanlike” and delay any future bid for the Conservative leadership until after the Commons Privileges Committee inquiry is concluded.Sky News
