I admit I don't really understand in depth but I keep hearing people saying that they'll vote out of the EU because of immigration.
The thing is the government haven't proposed what they'd do about immigration anyway in the event of us going out of the EU.
As a lot of Brits have retired abroad and we are still going to want to trade with all these countries. I've got the feeling that we will end up with free movement anyway as part of whatever deal we come to.
People keep going on about an Australian points style system but no one can be certain that, that will be what happens.
