The one saving grace I thought there might be about Johnson in this cataclysm is that, unlike Trump, he's aware the work does need to be done and (being lazy) has long relied on bringing in people who will do the donkey-work.
But that doesn't take away from the fact that he does actually need to take decisions, make sure stuff gets done, and show leadership.
I actually think he might retire under some excuse soon.
Look at his previous behaviour. He campaigned for Brexit; skedaddled as soon as it became real, dumping the hot potato in someone else's lap; then swanned back in when much of the hard work was done, to capitalise on the situation he'd caused.
Then he turned on a sixpence from "Get Brexit Done" to "People are bored with Brexit, don't talk about it," to distract from the delay and the inevitable failures to meet expectations.
He has zero appetite for hard work or taking responsibility. I reckon he'll stage a little health crisis and go rest in the country, leaving some other poor fucker carrying the can until the hard parts are over. Then he'll oil back in and act the hero.
