Starmer will convene a gathering of European leaders at Downing Street tomorrow, aimed at planning for how to police a future Ukraine peace deal.
The prime minister believes such a deal will have to involve the US.
But hopes for unity between European nations and America on Ukraine’s future has been shattered by the blowout between Trump and the Ukrainian leader.
He will also meet King Charles while he visits the UK for talks with European leaders, ITV News understands.
Discussions of this nature tend to take place on advice from the government.
The summit on Sunday will also include leaders from France, Germany, Denmark, Italy, Netherlands, Norway, Poland, Spain, Turkey, Finland, Sweden, Czechia and Romania, as well as the NATO secretary-general and the presidents of the European Commission and European Council.
Following the feisty discussion on Friday, Zelenskyy said America’s support for Ukraine is “crucial”.
The Ukrainian president and his team were asked to leave early after a fiery Oval Office meeting where Trump accused him of “gambling with World War Three” and US Vice President JD Vance called him “disrespectful”.
On Saturday, Zelenskyy sought to mend ties with Trump with a series of posts on social media.
He said: “We are very grateful to the United States for all the support. I’m thankful to President Trump, Congress for their bipartisan support, and American people.
“It’s crucial for us (Ukraine) to have President Trump’s support. He wants to end the war, but no one wants peace more than we do.
“We are the ones living this war in Ukraine. It’s a fight for our freedom, for our very survival.”
Trump attack
World leaders in Europe were quick to rally and express their support for Volodymyr Zelenskyy after his heated exchange with Donald Trump.
A number of leaders, including Canada’s Justin Trudeau, France’s Emmanuel Macron, Polish Prime Minister Donald Tusk and Germany’s Olaf Scholz, all tweeted their support after the Ukrainian leader was criticised.
Zelenskyy also spoke with Macron, NATO secretary general Mark Rutte and EU Council president Antonio Costa by phone.
It came as Zelenskyy portrayed the meeting as a moment of frank and divergent views between the two but said he did not see the need to apologise.
He added that he wished that Trump was “more on our side” after the US president said he was in the middle of Ukraine and Russia.
