There is a fair possibility of the breakup of the UK which is a country of countries (England, Scotland, Wales and Northern Ireland). However it is worth pointing out that although there is both a strong national identity in Scotland, Wales and Northern Ireland and a somewhat disparaging view of England and the English; Scotland, Wales and Northern Ireland all have their own devolved Parliaments except England. Furthermore, people from Scotland, Wales and Northern Ireland can vote on English laws dispite the reverse not being true. I think it's likely that more power will be devolved to Scotland, Wales and Northern Ireland in exchange for keeping within the UK. One of the main reasons for Scotland to remain was that it would not be allowed to use the pound if it broke away. Another key issue around a possible Scottish breakaway is Trident, the UK's ongoing independently-controlled nuclear deterrent. Trident is actually four submarines armed with ballistic missiles operated by the Royal Navy based at Clyde Naval Base on the west coast of Scotland. The costs of needing to relocate personnel and the base would be a major sticking point in any Scottish breakaway negotiation. Also the eurozone is extremely weak economically in part to needing to prop up the Euro and dealing with Greece. The point I'm trying to make here is that although a majority of Scots voted to stay in the EU, I'm not certain of their fondness of breaking away from the UK completely and going all in on the EU. What I think is more likely is that Scotland will do a sort of flip on how Greenland is within the Danish Realm and out of the EU but Denmark is part of the EU. Having said that if the EU is looking like it will collapse then Scotland will stay.
