I saw a claim on another forum that buried in the Lisbon Treaty is a provision to standardise the way healthcare is delivered across the EU.
Now I'm no expert on this but as far as I'm aware most countries on the continent operate a hybrid system where people have to have basic health insurance and governments pick up the tab for the rest via taxation. In the Republic of Ireland for example it costs about 60 Euros to see a GP I believe?
If this is true it seems likely that if we ended up staying in the EU and the EU decided to standardise healthcare, the government of the day would be forced to restructure the NHS to a European system where we all have to have health insurance and maybe even end the principle of free at the point of delivery.
The obvious answer is
No, we'd just Veto it!, but and this where it gets interesting as the EU are due to end national vetoes and issues will be decided with Qualified Majority Voting. So it seems likely that if this is true and happened, more countries would vote to keep the status quo rather than restructure their healthcare systems.
I havn't read the Lisbon Treaty so it might be a huge conspiracy theory, but it's an interesting thought non the less!
And the next time you come across some shouty Momentum leftie/remainer headbanger claiming that the Tories are going to sell the NHS to the Yanks, this is a handy comeback!
