Ukraine's President Volodymyr Zelensky says the group of allies, led by the UK and France, are needed to provide security guarantees.

The leaders arrived together at the train station in the capital, where they met Ukrainian president Volodymyr Zelensky. In a joint statement before their arrival, Sir Keir, Emmanuel Macron, Friedrich Mertz and Donald Tusk said that they are “ready to support peace talks as soon as possible”.
