I am (sort of) looking forward to a vote by Scotland to leave the UK (spoiler: they will not if we have already genuinely left the EU) - but anyway, just for the giggles.
So - step 1 they vote to Leave
Step 2, we, having learned from the experts, agree that first and foremost there has to be a WA and settlement on minor matters such as percentage of debt
Step 3, there is a protracted period of time during which all these issues of economic factors, such as level of trade with nearest market - percentage of trade that exists/is dependent on the UK etc. are made massive issues
Step 4, then we have a lot of discussions about the border issue - certainly not the UK's fucking problem is it. Whoo - what would the EU/Scotland do?
and so and so forth
(spoiler: it would not get to step 2)
Would be funny though if Scotland played hard-ball and threatened a 'no-deal' - best not let the rest of the UK be involved in a vote!!!
Just joking BTW
