You're asking me the same question, there should be a plan we are agreed on that. The laziness and stupidity of some people equating people showing concern over too much immigration with marching on Poland is spectacularly stupid.
That isn't a dig at you BTW, it's a dig at the idiots who invoke wee Tommy as some sort of weapon against people who don't agree with their views.
I am however yet to hear a benefit we would get from just allowing anyone in other than getting anal wipes deployed or the best coffee in town.
