An independent Scotland that keeps the pound would have to give up some national sovereignty to avoid the kind of risks exposed by the Eurozone crisis, Bank of England governor Mark Carney has warned.
Mr Carney said such a move, proposed by the Scottish government, "requires some ceding of national sovereignty".
He said there would have to be tight fiscal rules and a banking union to avoid risks seen in the Eurozone.
