Volodymyr Zelenskyy will meet the leaders of the UK, France and Germany in London on Monday to discuss the latest US-authored peace proposal aimed at ending Russia’s war in Ukraine.

Days of negotiations between US and Ukrainian officials ended on Saturday without an apparent breakthrough. The Ukrainian president called the discussions “constructive, although not easy”.

On Sunday night, Donald Trump said Zelenskyy “hasn’t yet read the proposal” and claimed without evidence that “his people love it”. Kyiv’s senior negotiator, Rustem Umerov, said Zelenskyy would be briefed about his team’s dialogue with US officials and receive all documents related to the peace plan on Monday.

Off the back of the Trump-backed Gaza ceasefire, the US has been working to push through a peace deal between Kyiv and Moscow. US officials claim they are in the final stage of reaching an agreement, but there is little sign that either Ukraine or Russia is willing to sign the framework deal drawn up by Trump’s negotiating team.

In his comments on Sunday, Trump said “Russia is, I believe, fine with [the deal], but I’m not sure that Zelenskyy’s fine with it. His people love it. But he isn’t ready.”

Zelenskyy will be received in London by the British prime minister, Keir Starmer, along with the German chancellor, Friedrich Merz, and the French president, Emmanuel Macron, to discuss the negotiations.

The British foreign secretary, Yvette Cooper, is, meanwhile, expected in Washington on Monday, where she will meet her US counterpart, Marco Rubio. “The UK and US will reaffirm their commitment to reaching a peace deal in Ukraine,” the Foreign Office in London said, announcing Cooper’s visit.

Washington’s initial plan to bring an end to the almost four-year war involved Ukraine surrendering land that Russia has not been able to win on the battlefield in return for security promises that fall short of Kyiv’s aspirations to join Nato. Despite ongoing efforts from Trump and his team to push through a deal, progress in the peace talks has been slow, with disputes over security guarantees for Kyiv and the status of Russian-occupied territory still unresolved.

Starmer has stressed repeatedly that Ukraine must determine its own future, and said a European peacekeeping force would play a “vital role” in guaranteeing the country’s security.

The Russian president, Vladimir Putin, has not publicly expressed approval for the White House plan and last week said that aspects of Trump’s proposal were unworkable. The US envoys Steve Witkoff and Jared Kushner met Putin at the Kremlin last week but failed to achieve an obvious breakthrough.

“The American representatives know the basic Ukrainian positions,” Zelenskyy said in his nightly video address on Sunday.

Trump has had a hot-and-cold relationship with Zelenskyy since reentering the White House, and has urged the Ukrainians repeatedly to cede land to Russia to bring an end to a conflict he says has cost far too many lives.

Zelenskyy said on Saturday he had a “substantive phone call” with the American officials engaged in the talks with a Ukrainian delegation in Florida. He said he had been given an update over the phone by US and Ukrainian officials at the talks.

“Ukraine is determined to keep working in good faith with the American side to genuinely achieve peace,” Zelenskyy wrote on social media.

Trump’s criticism of the Ukrainian president came as Russia on Sunday welcomed the Trump administration’s new national security strategy. The Kremlin spokesperson, Dmitry Peskov, said the updated strategic document, which spells out the administration’s core foreign policy interests, was largely in line with Moscow’s vision.

The document released Friday by the White House said the US wanted to improve its relationship with Russia after years of Moscow being treated as a global pariah. The document was also highly critical of European countries, and said that the continent was at risk of “civilisational erasure”.

Trump’s outgoing Ukraine envoy, Keith Kellogg, said at a defence forum on Saturday that the administration’s efforts to end the war were in “the last 10 metres”. He said there were two outstanding issues: territory and the fate of the Zaporizhzhia nuclear power plant.

Kellogg is seen as among the US officials most sympathetic to Kyiv’s position, but is due to leave his role in January and was present at the Florida talks. Many others in Trump’s orbit, including Witkoff, have been much more open to adopting Russian positions. Trump’s son, Donald Jr, said at a forum in Doha on Sunday that Zelenskyy was deliberately continuing the conflict for fear of losing power if it ended. He said the US would not be “the idiot with the chequebook” any longer.
