France and Italy are a huge part of the problem. Lots of hot air but they never seem to charge these would be migrants for their deeds. Of course then they'd be officially on record as being in that country and have to bear any asylum burden.
I'd sling any of these migrants that get to the UK in an all new Guantanemo or two on some remote Scottish Island and show them on web cams so the message gets through to those thinking it's worth trying. But then I'm all heart.
