Ultimatum to Putin from leaders of UK, France, Germany, Poland in Kyiv to act by Monday came after joint call with Trump

European leaders on a joint visit to Kyiv have issued an ultimatum to Vladimir Putin: sign up to an unconditional ceasefire by Monday, or face increased sanctions and weapons transfers to Ukraine.

The leaders of Britain, France, Germany and Poland, together with Volodymyr Zelenskyy, made a joint phone call to Donald Trump prior to making the announcement.

“All of us here, together with the US, are calling Putin out. If he’s serious about peace, then he has a chance to show it now,” said UK prime minister, Keir Starmer, at a joint press conference of the five leaders in Kyiv.
