This was the ballot paper. One of the more reliable guides as to what people voted for.
Four words, the verb being 'leave'.
I find it easier to discuss around those four words. The UK will leave the EU.
The UK is over here having 'left', the EU is over there.
Two separate entities with no instruction that those entities will be joined up in any way.
The vote was to 'leave'.
So once separate there is a border, (unless I am mistaken and leave actually means joined together.)
But lo!
Pesky Geography shows that the EU and the UK although apart are joined together by land.
The question remains after all this time about how exactly do you manifest leaving something you are physically joined together with on that actual land.
If those who voted leave knew what they voted for, perhaps they can tell the rest of us how they think it will be done.
