The clash came just a day after Sir Keir’s visit to the US, regarded as successful because the Prime Minister’s charm offensive with Mr Trump secured support for the Chagos Islands deal, and signs that he may be able to hold off US tariffs on British goods.
Mr Vance meanwhile accused the Ukrainian leader of being “disrespectful”, and both he and the US president claimed Mr Zelensky had not been thankful enough for US military aid.
Plans for the two countries to sign a minerals agreement, which would see continued US military support in exchange for developing Ukraine’s natural resources, were also put on hold when Mr Zelensky abruptly left the White House.
But hopes for unity between European nations and America on Ukraine’s future has been shattered by the Friday blowout between Mr Trump and Mr Zelensky in the Oval Office.
French President Emmanuel Macron, German Chancellor Olaf Scholz, Polish Prime Minister Donald Tusk and EU Commission president Ursula von der Leyen were among the leaders to express solidarity with Mr Zelensky.
