well the English,Welsh, Irish, and Scots can want as much as they want ...wether it be autonomy/Independence or whatever, the fact remains the Former UK is now part of the EU .
It will be up to EU commissioners how much power any former nation/state has , and if you read the Lisbon treaty/constitution that won't be much.
The EU is now on a roll to set up as a 'United States of Europe' if you like . It has always had an anthem and flag , now I have even heard it referred to as the EU National Anthem and National flag of the EU, by EU politicians . The final nail in the UK's coffin will be when the French and Germans take the London stock market apart , which they are already in the process of trying to do . Everything else (all the banks , building societies , what remained of any manufacturing industry we had ) is either being sold off to other EU members, or has been already . The stock market was the jewel in the UK's dwindling crown , having become one of the most powerfull markets in the world .
So enjoy whatever power you think you have, while you can , over the next year or so things are going to become very different . I don't mean that as a slur on any individual former country member, wether he/she be from Ireland, Scotland , Wales , N.Ireland or England , but just as a statement of fact . We do not have any individual political power left anymore , apart from what the EU Commission says we 'may' have.
cheers
