Theresa May dodged raising Donald Trump's condemnation of the NHS when they spoke on the phone last night.
the United States president sparked fury earlier this week with a Twitter outburst claiming the health service was 'going broke and not working'.
Downing Street rejected the criticism, while Health Secretary Jeremy Hunt took on Mr Trump by pointing out that millions of Americans have no provision.
The exchanges threatened to undermine efforts to get the Special Relationship back on track after a series of spatsincluding and extraordinary public row over Mr Trump's retweeting posts from a British far-right group.

But Mrs May did not mention the NHS when she spoke to Mr Trump last night, instead focusing on North Korea and the prospect of a new Transatlantic data-sharing deal.
A No10 spokesman stated Mrs May stressed the 'great importance' of a new US data law, which will also enable reciprocal deals to allow police in the UK to access information across the Atlantic.
'They discussed the Clarifying Lawful Overseas Use of Data (Cloud) Act, due to be considered by the United States Senate later this month,' the spokesman said.
'The act covers how the United States can access data stored in another country, when it is needed to prosecute serious crime or to disrupt terrorism.
'It will also authorise the United States attorney general to enter into agreements with like-minded allies like the UK to allow reciprocal compliance with US and foreign court orders.
'With it, law enforcement officials in the United States and the UK will be empowered to investigate their citizens suspected of terrorism and serious crimes like murder, human trafficking, and the s3xual abuse of children regardless of where the suspect's email or messages happen to be stored.
'The Prime Minister stressed the great importance of the legislation to the UK authorities in investigating criminal and terrorist activity in the UK.
'The Prime Minister and President Trump agreed the passage of the act through the United States legislative system was vital for our collective security.'

Asked if the issue of the NHS came up during the telephone call, Downing Street said: 'It did not.'
Triggering the row on Monday, Mr Trump posted on Twitter that 'thousands of people are marching' in the UK because of concerns about the state of the NHS.
the United States president made the attack as he targeted Democrats pushing for a British-style universal health system in the United States.
Mr Hunt responded with a tweet of his own, saying no-one protesting about the state of the NHS wanted a US-style system.
'NHS may have challenges but I'm proud to be from the country that invented universal coveragewhere all get care no matter the size of their bank balance,' he said.
Downing Street stated the Prime Minister was 'proud' of the NHS and its funding was 'at a record high'.
