The idea has been floated
that Boris may decide to launch himself into the premiership on the back of a radical about-face to call off Brexit and "save the nation" before one of his earstwhile colleagues duly does a Brutus on him. So the ERG get to blame Boris for the sabotage, the majority of MPs who were against this nonsense in the first place don't take any heat for having spines of their own and the nation gets to pick up the pieces from the disastrous last couple of years whilst narrowly avoiding a true nightmare. Short of a second referendum followed by a GE (still a possiblity), this would be an acceptable outcome despite the momentary shame of someone competing with Trump for World's Stupidest Leader running Westminster.
