Of course the Scots will have to take their share of the UK's national debt and pay for the construction and transfer of the N Sub Base to Falmouth.
I guess they'll want the Scots Guards & other Scottish Regts and may be a Friagte or two & a couple of squadrons of Typhoon etc. Fine, if they can afford it.
Personally, I'd rather we had a referendum on devolution for England. leave Westminster in charge of UK wide policy whilst Scotland, Wales, England & N Ireland looked after their own purely domestic issues. We'll have the English parliament in the centre, some where near Derby should be Ok. Should be able to slim down the Westminster and County Council machines but it will mean a whole new bunch of professional politicos at a national level. So be it.
