Once again Eddie is putting forward all sorts of nonsense without checking the facts. There is no uncertainty and here's the facts:
First of all, it will be in nobody’s interests to repatriate the UK citizens living in the EU and vice-versa. It simply wouldn’t happen. However, even if it was proposed, there is something called the Vienna Convention on Treaties. This is a United Nations document and it states (among many other things) that citizens who have taken advantage of provisions of a treaty (e.g. moved from the UK to settle in Spain under the various EEC and EU treaties, most recently the Lisbon Treaty) cannot be forced to lose the rights they acquired under that (or those) treaties. End of.
Look it up (I have – it’s a lengthy document and you have to dig through it to find the relevant passage. Regrettably so much nonsense is spouted in this entire debate when just a little digging will establish the true position. “Project Fear” has certainly done its stuff on many people and it does them no favours.
Of course there is always the chance that the remainder of the EU and the UK will ignore the Vienna Treaty and forcibly repatriate huindreds of thousands of people (over 300,000 EU citizens setlled in the UK in the last year alone). However, since there are far more people from the rest of the EU settled in the UK than there are UK citizens settled elsewhere in the EU, do you really think it likely?
