Well this is what the leave campaign homed in on. It was their trump card (allusion fully intended), to pander to the most basic and unreconstructed racist instincts of the British people, and it worked. Without the immigration issue, which is temporary (we were welcoming them with open arms ten years ago), the leave campaign would have been routed. But they played this card with all their night and it worked. Which makes Farage, Gove and Johnson a bunch of lying, racist bastards.
