"it's not any sane version of any of the originally-agreed models for Brexit. "
You mean there was an actual sane version of Brexit where the UK gets an even better deal with the rest of the EU than the one it's already got (which from the PoV of the other 27 is pretty f**king cushy) and yet stays inside the free market?
And people actually thought the rest of the EU would sign up to that?
Here's my rule.
When bad s**t happens and keeps on happening follow the money.
For those who know "The Night Manager" ask yourself "Who is the real Richard Roper?"
Biting the hand that feeds IT
