The UK paid out £674 million in health costs to European countries, but received only £49 million in return
so what does that mean @Clavinova ? To me it looks like EU nationals in the UK cost the UK £49 million which was repaid, but the UK nationals in the EU cost the UK £674 million - which can't be repaid ?
Numbers without context are just that. Numbers. Not reasoned answers in a sensible discussion.
