Good riddance to all of those who hate their country, we are all leavers as of tonight.
If Spain chooses to be part of the EU surely that is up-to the Spanish and in fairness it's their country.
Brits live everywhere - even in Wuhan - despite; political, human rights and animal welfare issues associated with the Chinese set-up. It should be noted that it wasn't the Chinese flying these expats home - it was the UK govt.
Accepting the Spanish way is incumbent on any residents granted temp or permanent rights to reside but unless you apply for citizenship you will for ever suckle upon the UK teat. It's an inconvenient truth that many who declare Britain bankrupt, financially, morally or intellectually have a stake in its continued success.
I am slightly more pragmatic - I love my country but will politely be asking the Spanish if I can live in theirs if I; respect their rules & pay my taxes. I doubt many apply for residency because of the political project but if they do I say that's okay - live and let live.
We live in a rules based world obey the rules and you are on the right side of the curve.
