As regards Scotland and Northern Ireland. It will be interesting what the next decade or two brings.
I know the SNP supported remaining. However, Nicola Sturgeon did speak of the will of the majority of the people of Scotland wanting to stay in.
Northern Ireland also voted to remain, but Arlene Foster seemed to ignore reference to the will of the majority of voters in Northern Ireland to remain in the EU. I may have missed it if she did.
If the billions poured into NI every year (11billion, I think) dries up, what effect will that have in relation to peoples satisfaction and the way Britain is viewed. It does provide a good subsidy at the moment and keeps NI in the clover. Combined with demographics near parity and a rising majority of the younger population from traditional non-Unionist backgrounds. They are not necessarily nationalist, but things could change. The extra EU money will have gone.
You feel anything could happen, really.
