If all else fails, there are a lot of people in England who would vote in a referendum to dump Scotland and accept Norway into the UK instead :-)
what will happen to all of us without it at least Norway is using the profit wisely Britain had oil and gas in the north sea we haven't a penny to show for it squandered the lot
Norway will have to import it
We'll find other things to invest in, like thorium, tourism, technology (a lot of T's!).
It will squeak.
