Article on new HO regulations concerning the rights of EU citizens in the UK:

On the face of it, these new rules would appear to give the HO the right to deport any EU citizen without permanent residency rights, who is not currently exercising treaty rights and who does not have private health insurance. This will include many EU spouses of UK citizens who are not currently working and cannot document a 5 year period during which they exercised treaty rights - regardless of the amount of time they have spent in the UK.
This gives a whole new slant to those HO letters suggesting that EU citizens make plans to leave. Might be time for affected EU citizens to consider legal advice :-/
(Weird and hostile way of opening negotiations with the EU27 over migrants' rights - I am coming to the conclusion that May may actually want the negotiations to fail).
