Rather annoyingly NI (where I'm from) didn't vote to leave, but its affecting us the worst (and sort of best) by far. A lot of Unionists won't accept being treated differently to the rest of the UK, and won't accept any kind of even theoretical border in thr Irish sea.

However we cannot have a border at all across Ireland. Funny enough the solution was an area of free movement, trade, and common laws.

Much like the EU.
