Mr. Johnson has not ruled out suspending Parliament to take Britain out of the European Union on Oct. 31, but last week lawmakers approved by 41 votes a measure that would make it harder to bypass Parliament.
Tobias Ellwood, a defense minister, told Sky News that even if Mr. Johnson pushed through a “no deal” Brexit he would have to “crawl back literally moments later” to ask the bloc for emergency arrangements. Amber Rudd, the work and pensions secretary, has also warned of a “collision with reality.”
Tony Blair, a former Labour Party prime minister, said that Mr. Johnson would, on arrival in Downing Street, be warned by officials that the European Union will not renegotiate the Irish backstop and that “no deal” is a huge risk.
“You have a thousand different issues as prime minister to deal with,” Mr. Blair said, “but in the short term he’s got one issue to deal with.”
Mr. Johnson would have to choose whether to back away from his promise to scrap the Irish backstop or try to pursue no deal — an outcome that could, if blocked by lawmakers, force a general election or possibly a second referendum, Mr. Blair said.
“He will face the facts and decide that if you try to engineer no deal without Parliament — against Parliament’s wishes — and without public endorsement, you better hope it works perfectly because if it doesn’t, you’re going to be in all sorts of difficulty for the rest of your time in politics,” Mr. Blair added.
