Two options:
No Brexit.
Or
Hard Brexit.
Hard Brexit won’t be great, but won’t be the end of days the ‘remoaners’ make out either. It will be bad if jack shit is decided in advance, but with planning on both sides it can be smooth and orderly.
In any divorce things get shitty on both sides, then once separated they hopefully get better for each party. What we have here is one side who wants to leave for party time, but doesn’t want to lose having their dinner on the table at six and a shag every now and then, and another side who is bitter about the affrontery and wishes to fuck them up unless they can be bullied in to staying.
Unedifying, to say the least.
