I have attempted to use the now standard "Devo" nomenclature, even though this reads like a soft drink menu. I have also given a brief description of each option. These are deliberately short, so I am sure many will take exception to my definitions.
Independence (Devo Ultra)
As currently proposed, this involves Scotland becoming a sovereign nation with all taxes and duties being levied by Edinburgh. Scotland would retain the pound, as well as partial ownership of the Bank of England, and the Queen would be the Head of State. Scotland would receive the full benefit of its natural resources, including oil and gas revenues. There would almost certainly be some cooperation with the rUK, for example on currency and defence matters, but sovereignty would rest with Scotland.
