"Firstly, one of the main themes of the Leave campaign was control of our borders. So, having "no border" between NI violates that."
I dont understand how people can get this simple concept so wrong. Control of our borders means our own choice over the border. If we dont want one that is 100% consistent with control as is anything else as long as we decide.
"It's all about how "hard" that border is"
Aka the EU's problem. Ireland (both sides) dont want a border. The UK wants frictionless trade so doesnt want a border. Oh wow thats simple then. Its the EU's problem if they want a border.
