"Trade takes place between England and Scotland because it is of mutual interest that it should happen, not because of English links with Scotland.

There is no reason in the world why trade should not continue if the political link was broken by independence."

At the time of the Independence Referendum there was a very good reason why trade would have been seriously affected had Scotland opted for Independence in 2014 - The UK would have been an EU Member State and the Newly Independent Scotland would not. This would have affected 80% of Scotland's trade.

As far as Scotland is concerned 80% of her trade and economy is connected to England and the United Kingdom and 20% with the rest of the world and the EU - so tell me which link is the more important.
