Remain, and not just because my girlfriend is Swedish either.
Given the recent terror attacks in Europe it is more important now than ever that 'we' band together. The EU is definitely not perfect but the solution is not to just try to break away and pursue an isolationist policy. The only arguments I have seen from the leave campaign have been 'immigrants' and the bullshit-£350m/week figure that I have had posted through my letter box at least three times within the last week.
I am quietly confident that it will be a case of the silent majority winning the vote (Remain). Similarly to the Scottish independence referendum 18 months ago, it is those who are trying to upset the status quo that tend to make the most noise.
