The issue of how we have handed over control of our immigration policy to our fellow EU members was brought home to me when chatting to a Brazilian babysitter. She told me she felt lucky to be able to work legally in London and stay as long as she wished, as she was Italian. Had she ever been to Italy? Never. Could she speak Italian? Not a word. But she had one long-dead Italian-born grandparent, who had emigrated to Brazil. She could thus claim Italian citizenship. She has since returned to Brazil, citing its booming economy. The same cannot be said of Moldova.
