I don't expect the UK to come out better off from this.

This may actually work really well for the opponents of separatist movements in developed nations.

Oh, Quebec won't ever leave. Even those who want to "leave" don't really mean leave. They always expected to keep Canadian money and passports. But we will have to live though a year of pathetic 'will they/won't they' news stories along with another round of French language laws and other things only the gray-haired care about.

... and Scotland, Ulster, Flanders, Catalonia, the Basque Country, Verona, Corsica. There are more separatist movements than one might think.
