We need the facts, but all we got was a political wishlist. We still don’t know what currency Scotland would use if we vote to go it alone. The nationalists want a currency union with the rest of the UK but their own civil servants have admitted that they can’t guarantee that. The problem is that the rest of the UK would have to agree to this – it looks increasingly like a non-starter. Even some nationalists see that a currency union would be a straitjacket, not independence.
