Ukrainian President Volodymyr Zelenskiy will meet British Prime Minister Keir Starmer in London on Thursday, ahead of US President Donald Trump’s talks with Russian President Vladimir Putin in Alaska on Friday, Reuters reported.

Zelenskiy, who attended a virtual meeting with Trump and European leaders on Wednesday, urged against concessions to Moscow and warned that Putin is “bluffing” about ending the war. Trump responded by threatening “severe consequences,” including possible sanctions, if Putin rejects peace terms.

Trump said the Alaska meeting aims to “set the table” for a follow-up involving both Zelenskiy and Putin. Britain, France and Germany — co-chairs of the “Coalition of the Willing” — outlined their ceasefire position after Wednesday’s talks, according to Reuters.
