Scottish independence would come at a high price...

"In two years’ time the people of Scotland will be asked whether they want to become an independent sovereign state. It is not often that a 300-year-old union is broken, so the vote will have ramifications far beyond a land of 5m people. Scottish independence could lead to a break-up of the United Kingdom. The Catalans, among other disaffected European groups, see Scottish independence as a harbinger of their own bid for nationhood. Other diverse nation-states watch, and worry."
