Sir Keir Starmer has insisted that Russia has a weak hand in talks to end the Ukraine war and could be pushed into making concessions.

The Prime Minister said Vladimir Putin, the Russian president, did “not hold all the cards” as he addressed world leaders at a summit in Kyiv to mark the third anniversary of the Kremlin’s invasion.

His comments could be seen as a veiled swipe at Donald Trump, the US president, who has been accused of giving away too much to Russia following initial talks in Saudi Arabia. Sir Keir will meet with Mr Trump at the White House on Thursday.

The Prime Minister also said in his speech on Monday that world leaders were “united in opposition to Russia’s barbaric invasion”.

However, he warned that nations had to be bolder in supporting Ukraine, including via extra military support and sanctions against Russian banks and oil giants.
