I agree with all of that Nigel but it does not address the key question. If the US insist they do get access the aspects of the NHS or they no deal, do we say ok or do we no deal?
That would have to depend on what aspects of the NHS they were asking for access to, and what we would be getting in return. As a general question, with no specifics, it makes little or no sense.
We need (once Brexit is achieved) an opening stance for any negotiations.
Two positions which would be equally ridiculous are:
We will give you full access to all aspects of NHS even if we get nothing in return.
and:
No matter what you offer us we will never allow you access to any aspects of the NHS under any circumstances.
