I know the Brits abroad stereotype is one of them all being pensioners but is that actually correct? Not according to the FT which claims that out of the 1.8 million Britons living elsewhere in Europe 400,000 are claiming a state pension so about 78% are not British pensioners. 22% are pensioners which is slightly higher than their share of the UK population which is about 17% but not that much higher. So there potentially could be 1 million Brits have their rights to abode in Spain at risk! Do UKIP consider this. Just how do you think Spanish residents would be able to come back with their assets if their assets are tied up in Spanish property which is at a low!

Surely UKIP or the Tory right can say what it would offer existing immigrants from the EU but they have no control over how other EU countries would view the situation?

I don't think UKIP are planning on sending anyone back, just on restricting further immigration. So the analogy with UK ex-pats having to come back isn't a valid one. "Tit-for-tat" restrictions would just restrict new emigration of ex-pats.
