What is interesting is that there is a negative correlation between proportional Brexit vote and numbers of migrants - in other words places with tiny numbers of migrants voted most heavily for brexit and vice versa. So the issue of migration wasn't one of reality (people in consitutencies 'over-run' with migrants voting leave) but perception - people in constituencies where migrants were as rare as hen's teeth voting leave because of a perceived problem of migration, which clearly didn't affect their locality.
Do you have the stats for that?
I've mentioned my mate in Grimsby before. He works as a long haul driver for an agency. One day they are all told that a group of Polish drivers have arrived looking for work, they will do it for less so everyone has to take a wage cut or they won't get work. Not long after, both Brits and Poles are told to take another wage cut because the Romanian drivers have arrived. And the likelihood of this being a rogue employer is what, exactly?
Or in my neck of the woods, the head of Cambs police is on television giving an interview saying that she can't police the county effectively due to Eastern European migrants feuding. They don't bother the locals, just bring over ancient disagreements from their homelands and stab each other, and as she pointed out, that needs policing in a county where the village bobby on a bike is still a thing. So the character of a place changes.
I love the fact that I can find Polish branded food in my local supermarket. We like to try some of it. But to others that will be a change too. Are we 'overrun'? No, but this is new and there will be people who don't like it, just as much as I think it is something to enjoy.
