Cameron's resignation, then Osborne's sacking after Brexit, shows me that if the Independance result had been a Yes, then the same scenario could have been played out. As you stated above,different Chancellor,different outlook. The fact that the BofE were making contingency plans show's a union is possible.Without a currency union the UK's exit from the EU will be extremely difficult. Scotland's exit from the UK will be equally so.Independance,as Brexit will not be done overnight,but as many other countries have shown,it can be done and be a success.
