How Boris Johnson sealed Theresa May's doom

Boris' manoeuvres with his backbench colleagues have made it impossible for the PM to have her Brexit plan approved - were she to put her Withdrawal Agreement Bill to a vote, as she still promises to do - because he has persuaded them there is an escape from the Brexit deadlock that is destroying their party but not while she is in 10 Downing Street. It has been put to me as uncontroversial and incontrovertible truth by senior members of the Cabinet whose Brexit credentials are at best moot. 'What Boris did was convince my colleagues that if he were PM, he could persuade Brussels to ditch the hated backstop,' said one. 'Or rather that it is worth a go. And if he fails then it is full steam ahead to a no-deal Brexit, though with proper preparation'.
