> but not UK or others wanting to leave.
I don't think there are any others wanting to leave after Brexit! Politicians like Le Pen don't campaign to leave any more.
The AFD is openly campaigning on it and they are currently the most popular parti in Germany.
The French RN is not openly campaigning on leaving anymore since its pretty scary to the voters but the intention of Le Pen is to hold a referendum to ask the French people to recognize the supreme rule of French law above EU law which would act as a soft exit since that means that France would no longer be bound by directives and other regulations which it doesnt agree with.
The other major parti France unbowed is even more direct and wants to set "fire" to some of the debt which would most likely trigger a Euro/Eu crisis and force either the ECB to bail out France or force France out of the Euro.
It's become serious in German, Austria, and Czechia. The sentiment in France is not insignificant either.
I hear a lot about how the UK has suffered after Brexit, but none of my experiences there support it. Not the people I talk to, not my own experiences from before vs. after. I think people _want_ it to be true, which I find ugly.
