Mr Zelensky said: "A long, meaningful conversation with President Trump, first one-on-one, and then also with the participation of European leaders. In total, we talked for more than an hour and a half, about an hour with President Trump. Ukraine once again confirms that it is ready to work as productively as possible for the sake of peace."

His remarks came as Sir Keir Starmer said there was now a “viable” opportunity to reach a ceasefire in the Ukraine war. Trump is expected to make this a priority in Friday’s talks and has threatened Russia with “very severe consequences” if Putin refuses to end the war.

Zelensky said so after holding a call with Trump, during which the US President informed him about the "main points" of his talks with Russia's Putin in Alaska.
