Oil
The concept of Scottish Oil is interesting as its taken from outside the 12 mile limit; perhaps you should be worried that more and more oil from the North Sea is coming ashore here in Norway. Do the Shetlands and Hebrides get a vote on independence from Scotland? Will Scotland pay a proportion of the UK National Debt that exists - perhaps pro-rata with the defence assets they say they are entitled to? Absolute pipedream; the Scots voted in the SNP because they didn't want the Tories or Labour running the show - they've been able to eat their cake for too long and when they realise what Independence is, and will cost them, the answer will be (unfortunately) a firm NO.
