> Leave and remain have completely incompatible visions for post-Brexit Britain.

This would have been less of a problem if Leave had itself been a single position, rather than as it turned out to be several different positions that all started off in the same vague direction but pulled apart almost immediately, with those involved all insisting the rest of them "weren't proper Brexit" or were "secret Remainers", ignoring all the times Temainers said "What? Them? They aren't Remainers!" unless said Remainers pointed out this division at which point all these supposed "secret Remainers" who wanted something that wasn't "proper Brexit" suddenly were totes Leavers what are you talking about.

But yeah, polycrisis, and it's not just the UK, but the UK seems to have it worse than most because Brexit added to it.
