You can cite the numbers pissing off ?
I do but look it up for yourself.
You still haven't said what glorious benefit you believe to being a member of the EU? Are you another proponent of unfettered migration? What about the £160 million we literally give away every week and get nought back, are you in favour of this too?
And talking about the NHS, if we didn't have so many migrants in London in the first place there would be few waiting lists for hospital places and an appointment with a GP might take a day instead of four or five.
It is the number of migrants in London which has caused the problem, throwing more migrants at it won't make it better.
Sadiq Khan revealed a few years back that there were some 300,000 illegals living and working in London. I think its double that figure but never mind. The first thing we should do is round up these illegals and ship them out. Many are criminals, most have been refused entry, these are the sort of undesirables our country can well do without. Hopefully a new pro #Brexit Tory government will get to grip with this problem sooner rather than later.
