Meanwhile, a Downing Street spokesperson said of Sir Keir and Ms von der Leyen's call: "Ahead of the three-year anniversary of Russia's barbaric illegal war, they discussed the need to secure a just and enduring peace in Ukraine, and agreed that Europe must step up for the good of collective European security.".
In a Downing Street readout of Sir Keir's call with Mr Zelenskyy, a spokesperson said: "The prime minister began by reiterating the UK's ironclad support for Ukraine and commitment to securing a just and enduring peace to bring an end to Russia's illegal war.
On Saturday afternoon, Sir Keir also spoke with Finland's president Alexander Stubb and discussed "the need to secure enduring peace for Ukraine and bring an end to Russia's illegal war", a Downing Street readout said.
The US president also said a deal on minerals in Ukraine in exchange for weapons was close, but a source with knowledge of the negotiations told Sky News the Ukrainian president is not ready to sign and sees a "number of problematic issues" with the draft agreement.
The US president's recent statements, which echo Russian president Vladimir Putin's narrative, and plans to have direct negotiations with Moscow about the end of the war in Ukraine have left European allies and Ukrainian officials worried.
