If Scotland votes to leave the UK (not that it will but let us suppose) they will, presumably, have to apply for EU membership, which is what Alex Salmond longs for. However, the country they will leave behind will be very different from the one that became member of the then European Economic Community, which gradually transmogrified into just the European Community and, after the Maastricht Treaty, into the European Union. Will the remaining parts, England, Wales and Northern Ireland have to reapply? That could be interesting.
