I understand that other EU countries bill the UK for health treatment for expats treated abroad. So, for instance, if a Brit has public health treatment in France, the UK taxpayer eventually picks up the bill under EU reciprocal arrangements. It should happen in reverse, but despite the larger number of Europeans treated in UK, we recoup less than one tenth of what we pay out! Says something about the accountability of the NHS. Unfortunately, I cant remember where I read this, so treat the figures with caution.
Just saying!!
