you'll end up with 'Europe' as no more than the original EU-6.

I dunno, I think we could properly add Spain, Portugal, Ireland, Finland, Sweden, Austria, maybe Denmark, probably Greece and even most of the "New European" (tm) nations for sure (some notable exceptions) and we'd end up with a proper Europe.

But the EU-6 would have been much easier to make a properly social Europe than the one which was expanded to include the Brits. That goes without saying.

And make it a properly social Europe and you won't find any lefties opposed to it anymore.
