//Ross McEwan, its outgoing boss, said the bank would be too big for the economy Scotland and could not rely on another taxpayer-funded bailout.//
Does this mean they might be looking for yet another bailout? If so, England are welcome to them. Doesn't matter a whit where the bank is based (apart from a loss of jobs of course) most bank on the internet these days and there will still be plenty of local banks for those who need them.
Interesting wee read here about banking history. Remember that the Bank of England was founded by a Scotsman, William Paterson. We're still far ahead of the game.
