The Scottish vote makes no difference here. Manchester is part of England, Britain and the UK.
The United Kingdom is the union of Northern Ireland and Britain
Britain is the union of England, Scotland and Wales. The election is about Scotland leaving Britain and by extension the United Kingdom. The state of Manchester was never in doubt.
As I type, thank expletive deleted, Scotland have voted to remain part of Britain and the UK. Had they not I’d be moving to Scotland because otherwise what remains of the UK would never of got rid of the Tories (Conservative party)
It was a close vote though 55% to 45% with one area still to report, though not big enough to change the overall result.
I’m English but used to live in Scotland, near Glasgow, if I were still there I would have voted for independence.
