In the Tory dream world England is the 51st state of the US with all the trapping of corruption and greed. The billionaires in control of the Tory party are no different to the Russian oligarchs, asset stripping anything they come into contact with is their MO, taking the wealth of a nation and pocketing it.
I think the EU for their part see this and are happy to let England f**k itself up, but it has a desire to save Scotland and Ireland from this and in all likelihood will work surreptitiously to enable independence/reunification in the medium to long term.
What the Tories/little Englanders don't quite grasp is the dislike for England/Britain the world over for their imperial past, the best part of every country the world over would love to stick it to Britain and in time the US EU etc might just do that. Very bleak times ahead for genuine working class and blue collar people in Britain as the country descends into a pound shop version of Trumps America. Those at the low end of the spectrum in terms of income including the underclass, and ethnic minority groups and LGBT+ will have it worse again.
