Sorry, another economic point. Robert Peston gives his view on what Mr Salmond would have to do on Friday morning to prevent a run on Scottish banks:
BBC News - How Scotland can avoid a credit crunch
Rather ironically it would involve him having to backtrack somewhat on his currency union pledge, at least initially. Given that he would have achieved his objective by then, I don't suppose this would weigh too heavily on his conscience.
...The rigs are well protected at present, but will Scotland choose to have a force of their own that can do this?...
An area of potential mutual interest with rUK. Once the 'electioneering' rhetoric has stopped, there ought to be some cold, hard, rational discussion about shared objectives and this issue ought to be one of them. Of course, that makes it equally true that what would need to happen is already happening but that is not quite where we are now, at least not until Friday morning (possibly).
