Britain and France will lead a European “coalition of the willing” to provide security guarantees to Ukraine and enable peace negotiations with Russia, Sir Keir Starmer said.

The Prime Minister said he and Emmanuel Macron, the president of France, were working together on a security plan which is believed to include peacekeeping troops on the ground.

This European security guarantee would then be put to the US for approval, Sir Keir added.

Speaking to the BBC, he was unable to say that Donald Trump had agreed to US security guarantees for any peace deal, saying discussions were ongoing.

Sir Keir will meet European leaders later on Sunday in London to discuss support for Ukraine. Canada will also be represented at the talks.

It comes two days after Volodymyr Zelensky, the Ukrainian president, endured a fiery meeting with Mr Trump in the White House.
