Contrary to the widespread belief here on FR, the United Kingdom also refused to participate in this quota scheme (a little-acknowledged stand taken by the Cameron government). And because the UK isn’t in the Schengen open borders area, but controls its own borders, there was nothing Merkel et al could do to enforce it. Hence the notorious ‘jungle’ camps at Calais etc, of those who had made it across the Europe to the Channel but were blocked at the UK border.
Good to hear.
