I have no idea which way it would go. However, the whole issue is unsettling for business and is contributing to create a society where we are introverted in our views to other nations. Xenophobia is on the rise. The more it is publicised and the more traction the out campaign gets, the more legitimate it is perceived to be.
I'd say that very much depends. At this moment in time I doubt opinions are any different than they were before a referendum was on the cards. If the no camp do a decent job of campaigning then it will hopefully help matters considerably.
Sadly, all of the parties seemed to play the card that immigration was something to clamp down on. I'd like to think that with electioneering out of the way then there can be a return to reason and we can begin to highlight how great being part of the global village is, whether socially or economically.
