The bribe paid to those with the power to ensure a vote for the union was termed "the equivelent" and meant that Scotland took on part of the national debt of England, Scotland having no national debt at the time.
If Scotland chose to declare UDI we would start with a clean sheet with no national debt which at present for the UK totals some £1.5 trillion pounds, however the present regime in Scotland have agreed to take the proportional share of this debt being £126 billion pounds which would mean an annual payment of £4 billion pounds in interest.
This of course would be managable due to the fact that the full cost, £27 billion pounds, of the nuclear weapons of mass destruction based on the Clyde is at present fully set off as a charge against Scotland, this being removed would leave a surplus of £23 billion which could be used for the good of the country and its people.
