You are missing something. Even if Britain "pulls up the drawbridge" as you say and re-writes the rules. Expats in Spain, Italy and other EU countries are STILL bound by the EU rules (and international Law) Many non-Europeans live and work in places like Italy amongst them Russians, Australians, Canadians, Americans, Chinese, Japanese. How do you think that they could discriminate against British without having to do the same to all other nationalities. Just would not happen as they have too much to lose, never mind the illegality of such an action. Lies and more lies coming from the remain camp.
