Well, I've got a second vote.

Too tired for the rest just now, but as far as I can recall there were actually very few Poles that entered the UK when the border was opened to them - and most of them were here temporarily for work, not planning to stay permanently.

Unfortunately, I live way up North, so we don't get many chunnelers up here. However, a good chunk of the medics in my year ain't from around here...
