They may win today too. Although even if they do various polls have shown that the majority of Scots do not favour breaking away from the rest of the Union to form their own country.
But what if they did win the vote for an Independent Scotland?
Would that mean we'd have to reactivate Hadrian's Wall and use it as one big Passport and Customs Control? Afterall, all Scots would be illegal immigrants in England and would need VISA's to stay living and working here because they would no longer be part of the United Kingdom nor would they be part of the European Union which allows free movement of EU citizens.
So, we'd have to deport all the Scots and they'd have to go through all the red tape to come back in. Or wait until Scotland successfully applied for EU membership which could, because of the process, take years!
Hadrian's Wall could be the Scots/English version of the Mexican Border proposals!
