Later today, Volodymyr Zelensky is joining European leaders in talks aimed at increasing pressure on Donald Trump to side with Ukraine during Friday’s summit with Vladimir Putin in Alaska. Here’s what we know about these conversations:
German Chancellor Friedrich Merz called the meeting and Ukraine’s president is travelling to Berlin to join him for the video call with other European leaders, including UK Prime Minister Keir Starmer, and French president Emmanuel Macron.
Other key figures expected to participate this afternoon are Nato chief Marke Rutte, European Commission President Ursula Von der Leyen and the leaders of Finland, France, Italy and Poland.
They are then expected to talk to Trump and Vice President JD Vance in a second round of the conference call. It is not clear if all the previous meeting’s attendees will speak to the US president and his deputy.
Starmer, Macron and Merz are then also set to hold a round of talks of the so-called coalition of the willing, a group of Ukraine’s backers in Europe who have expressed a desire to provide security guarantees for the country once a ceasefire has been agreed.
