Well, I can see there is strong incentive for BJ to step down citing both 'health' and/or 'family' circumstances (see Kellyanne Conway's recent decision).
Both reasons conveniently covering for the reality of him finding out the PM job is not as much fun as he thought, he's now done it, and can leave No 10 with a mighty sigh of relief and move swiftly on to the £10k per evening speaking engagement circuit doing what he loves best speaking to a carefully curated adoring audience with glass of wine to hand.
Where, exactly, does that leave the rest of us? Utterly screwed over I'd suggest.
There's a good chance that the Leave vote might never had nudged past the 50% without his particular brand of breezy reassurances. So many casual brexiteers and Tory voters voted for him rather than either Tory or Brexit (knowing precisely nothing about the implications of the latter). As one older voter told me her utterly mistaken belief that "he's got a bit of welly".
It was all such a lark reaching his Churchillian destiny, but now, no hard feelings hey, it's time to move. Well he better not stick us with Gove or, god forbid, Patel or Raab! I've been in too many jobs where the hope for a good replacement for the mediocre boss has resulted in an even worse candidate. So too bad the job's not so fun. He bloody well better stick it out and to own and solve the mess he's created.
Anyhow, The Mirror says it's nonsense that he's leaving so our fears of his imminent departure are groundless
