European leaders, as well as the Nato chief, joining Zelensky for talks with Trump in Washington makes it an extraordinarily high-level meeting. This reveals how high their concern is that the US president will help Vladimir Putin defeat Ukraine by backing his demands - such as no ceasefire before final settlement.

Trump will greet Zelensky the White House at 1pm local time (6pm BST) and the pair will then have a bilateral meeting beginning at 1.15pm (6.15pm). Following this, Trump will take part in a meeting with European leaders who have travelled to Washington to back Zelensky - this meeting is scheduled for 3pm local time (8pm BST).
