It seems that Scotland now doesn't share anything with the rest of the union
So instead of letting them getting angry about being controlled by London then bizarrely signing to unelected officials in Europe, how about federalisation.
Scotland can control it's own 'domestic' policies, get its own tax, be responsible to the people of Scotland.
England can have its own Parliament - hell it's mainly conservative looking at the map - same domestic tax.
Energy, defence, finance (eg banks, markets etc) come under national.
Oh and if the Scots complain about Oil, you can have that on condition that you pay back the money given to you when you bankrupted yourselves chasing the slavery economy
HT to the wife for suggesting this!
