In reply to MargieB:
Merkel must be considering if she should part ground with Junker to save a Europe that may shatter without some flexibility in its four principles- especially the freedom of movement principle, if this is proving to divide Europe itself .
I see this as who is going to blink first.
If Europe don't blink, and stick rigidly to their 4 principles , then I can see that the whole thing is likely to fragment sooner rather than later.
If the EU do blink, and they find can relax the 4 principles, for everyone, then the U.K. will still leave, but , may get a 'better deal.' because everyone gets it.
( it will then be a pity that they did not concede that during the 'negotiations' with David Cameron( remember him)
