// As a resident of France, your fears will be realised. ///
I think jomifl need have no fears about Brexit. Figures vary, but there are about as many French people living in the UK, mostly in London and availing themselves of the NHS as UK citizens living in France receiving reciprocal health care.
The roads of Britain are saturated with cars made in Germany and France with only a minuscule amount of cars manufactured in Britain on the roads in the EU, - they need the UK more than the UK needs them.
The EU in its present form is a failed experiment, a monstrous non-democratic, out of control political nightmare incapable of being reformed from the bottom up. Brexit would not only be good for Britain it would be good for the EU too because it will have to re-invent itself along more democratic lines.
