This is another way of saying that nothing will change at the border itself - people from countries such as France and Belgium have never needed Visas to travel to the UK. with, or without either Schengen or the EU, and that is not going to change. Try to change this and you will destroy tourism in the UK. What the text actually meant was that the effective border moves elsewhere ie. access to jobs, housing and benefits. So the expression 'Hard Border' is nothing but hot air. The problem is that there is too much casual, non contract, cash in hand and semi legal work on offer in the UK. this is why so many actually go there. In Germany it would be impossible because every worker has to have a bank account in Germany, be registered with the local authorities, have health insurance here etc. etc. otherwise nothing works. All the controls you need to actually reduce unwanted immigration are actually already there within EU. law.
We have covered this several times, yawn. We all agree there needs to be tighter controls on who is in the UK.
