@izzythepush,
I really think that in trade agreements governments retain the right to regulate public services.
At best, neither the ambassador nor Trump know what the NHS is.
Just a reminder: in the UK they have the
NHS England,
NHS Scotland,
NHS Wales, and the
Health and Social Care (HSC) in Northern Ireland - each health service system operating independently.
And - nota bene! - the UK Government is only responsible for England's NHS (the the Scottish Government, the Welsh Government, and the Northern Ireland Executive for theirs).
