France’s Emmanuel Macron is in Washington for talks with Mr Trump ahead of Sir Keir’s own visit to the White House later this week, as European leaders attempt to show a united front in support of Ukraine.
Some European leaders and opposition figures have openly condemned Mr Trump’s remarks about Ukraine and Sir Keir has faced pressure to challenge the president when he visits Washington.
On a day of intensive diplomatic activity, Sir Keir said: “Three years on from Putin’s barbaric full-scale invasion of Ukraine, we face a once-in-a-generation moment for our collective security and values.
The Prime Minister will join a call with leaders including US President Donald Trump, whose overtures to Russia’s Vladimir Putin have alarmed Ukraine’s allies.
Sir Keir Starmer said the West faces a “once-in-a-generation moment” as world leaders marked the third anniversary of Russia’s invasion of Ukraine.
