Funny thing is about this, if the Scots go this route then it will make the Conservative party in England that much stronger due to the lack of Scottish labour MPs.
If scots vote for independance closer relations to the EU are almost assured, if only to spite eurosceptic english, and balance out english influence.
Unlikely. Members of the EU have already stated they will block Scotlands bid to join the EU (which won't happen for a number of years anyway).
Particularly if the Scots choose to use the pound. Which basically negates any form of independence they would have had anyway as they won't have a central bank if they choose the currency union route and it would all be controlled from London.
Salmond's main argument for an economically viable Scotland has always been the oil. But it's already been argued against multiple times that he is massively overstating the revenues from this and the length of time those reserves are going to last.
Unfortunately he is all talk with very little planning. All he does is shout people down the moment they disagree with him and a large number of Scots are foolish enough to go along with his blind nationalism.
Regardless, either way I'm not particularly bothered, and recently after the promise of more power to Scottish parliament in the event of a no vote I'd honestly prefer them to say yes. At least that way we won't have to deal with another idiotic labour Government and more drain on British resources to the Scottish.
Amusingly a large number of big chains have already advised that prices will rise in Scotland due to the fact costs won't be subsidised from Westminster any more. Everything from broadband (costs more due to distances in Scotland), down to food.
I also find it somewhat foolish that the Scots would consider leaving a Union that actually allows them to consider leaving democratically. There aren't many places in the world where that would be possible and such a peaceful and democratic situation is a bit daft to turn your back on.
