Imagine we vote for independence, there is a big fanfare and event around the re-convening of the Parliament and then the Queen does a wee day-trip up to give us our independence and make our democratically elected MPs swear an oath of allegiance to her. That would not go down well at all. Independence campaign would very easily become a republican campaign.
Seize the Crown Estate and the Palace of Holyroodhouse as the residence for our President (maybe call it Toiseach like our Irish brother call their PM) - President should just spend all his time promoting Scotland and Scottish culture, invite all world leaders and billionaires round to get pished on Scotch whisky. dine on Scottish salmond, helicopter trips up to the Highlands. Watch the inward investment of USD and RMB roll in.
