Nationalism the fashionable form of government

The future of the UK is under serious threat I think. Wales isn’t an outrider, just a slower burner because it’s been under English rule much longer - nobody is more proud of their own nation than the Welsh.
The model of government needs to change in England too, with less central government control and more regional power.

Can't speak for NI or anywhere else but I will speak for Scotland. The parties wanting independence in Scotland are not nationalist in the sense that they want independence because they think other countries are inferior to theirs. They want independence to pursue their own objectives. At the risk of making tasteless comparisons, nobody is blaming Ukraine or Finland for not wanting to be part of Russia.

Many Scots don't want to be part of the UK, but that is different to dangerous nationalism.

World events, polarising opinions, dissatisfaction with the status quo, disenfranchisement from the Westminster bubble ...
