It is very different. All of the regions you site elect MPs to Westminster and can vote on ALL legislation before parliament.
In addition those regions have their own parliaments, to which all members are elected.
The thorny issue is what the late Enoch Powell called the "
West Lothian question". This is an unresolved issue, and concerns MPs from Scotalnd being able to vote on English laws, but English MPs can not vote on Scottish law.
The bigger issue is that the UK is a highly democratic union. The EU is anything but.
Yonker, Schultz and Co, are NOT elected. It is a tyranny, and the UK is well shot of it.
Americans would never stand for such an arrangement as the EU, but would be quite content with the electoral oversight of the UK.
It is all about electoral oversight.
Imagine if the UK civil service could just write laws for Scotland or Wales without out their legislative bodies having a say or being able to over ride or change the law. And now imagine that 60% of your laws were now enacted without your Parliaments consent or agreement. Well that IS the EU. Yes, there are MEPS, in the European parliament, but they have no power. When they do try and exert it they are over ridden by the likes of Yonker. Most Europeans have no idea who their MEOS are, unless they are lucky enough to have a Nigel Farage who can turn the European Parliament sessions into a blood sport and embarrass the clowns again and again.
