How did you work that one out?
Sometimes this forum amazes me, we compete for investment across the world, every country does but for some bizarre reason we cannot compete with Scotland if they gain independence. As I said only moments ago, Scotland's industries are not Scottish they are British - nobody invests in Scotland because it is Scotland but because it is a constituent part of the United Kingdom.
If it left the UK and left the European Union it would no longer be part of the world's largest free trade zone and customs union and will no longer be a constituent in one of the world's most secure and stable currencies. We would be forced to institute customs restrictions on Scotland and domestic politics would likely ensure immigration restrictions as well whilst they have to magic a currency out of nowhere and use that to service their share of the UK national debt which would put a new currency under severe pressure from the very beginning.
Countries competing with each other is the way of the world and we as England are in a far stronger position than Scotland is - would you invest in a country with 57.5 million people with guaranteed access to 500 million more or would you invest in a country with less than 5.5 million with guaranteed access to nobody?
If they leave the UK then they can expect to be in open competition with us from the day they gain independence, as they would be with every other country in the world as we are at this very moment, any other stance would be very highly naiive.
Why should they leave the European Union? When I've heard Salmond he seems quite pro-EU.
