Know what's funny? The way politics is going, this could happen but with whoever becomes PM after Sunak because HOO BOY SHIT'S GETTING REALLY FUCKING WILD HERE.
Like the current PM made a transphobic Jibe to the Leader of the opposition WHILE THE MOTHER OF A MURDERED TRANSGENDER TEENAGER WAS IN THE FUCKING GALLERY and refused to apologize. Not to long ago we had a scheme to make kids sing this fucking bullshit in schools because people identify with their home nation more than the UK, not to mention all the absolute horseshit that regularly comes out of the UK.
The UK was never a nation state to begin with. it's traditions are are shallow as bathwater, mainly based around the Empire, which people are quickly realising is a bad thing. It's four, some would even say five nations poorly stapled together with little interplay between the cultures. Each nation sees itself as it's own thing with it's own politics, identity, culture, ideologies, and even languages.
The UK is about as much a nation state as Yugoslavia was.
