Scottish independence: Shared currency 'best for UK'
The SNP has rebuffed criticism of a white paper which sets out what it calls a "mission statement" for Scotland's future.
The head of the Better Together campaign, former UK chancellor Alistair Darling, has accused the SNP of "ducking the big questions".
Discussing the question of a shared currency, deputy First Minister Nicola Sturgeon said that currency union was in the best interests of the rest of the UK, as well as Scotland.
