Donald Trump has been "disrespectful" towards the prime minister and the UK, Foreign Secretary Jeremy Hunt has said.
His comments come after President Trump called Sir Kim Darroch, the UK ambassador to the US, "a very stupid guy" amid a row over leaked emails.
He went on to criticise Theresa May over Brexit, saying she had ignored his advice and gone her "own foolish way".
On Sunday emails revealed the ambassador had called the Trump administration "clumsy and inept".
Hunt responded to Trump's latest outburst by tweeting: "Friends speak frankly so I will: these comments are disrespectful and wrong to our prime minister and my country."
