I can't tell if you aren't aware he resigned or if your meaning here is that you figure Johnson will stand, be re-elected by his MPs and then pretend everything is back to normal, presumably while continuing to leak MPs to both by-election defeats and defections.
I wouldn't put it past Boris to attempt such a thing, but my guess is that it would be humiliating. There are dozens of MPs who'd back Boris in the hope of some reward, but far more see this as a useless cause and want to be first in line for a ministerial job under one of his rivals who might survive a general election.
No, I was not yet of that aware at the time of writing.
He resigned yesterday, he's been brought down. But it wasn't really the economy, I think, as much as people harbouring hopes of being PM getting sick of being made to look idiots by his constantly changing stories.
Didn't he resigned yesterday because of the scandals????
But the economy is a very basic, essential thing. If it is bad, things are indeed bad for many people, which counts more to them than the great politic.
Johnson would not have to worry about anything, if the UK's economy would be running smoothly. Which it does not and the brexit is basically still unsolved and a great feeling of insecurity remains. This might finally bring him down, not all the scandals.
