Volodymyr Zelensky will fly to London on Thursday for a meeting with Sir Keir Starmer.

Mr Zelensky, the Ukrainian president, will meet the Prime Minister and Mark Rutte, the Nato secretary general, for talks. It is Mr Rutte’s first visit to the UK in the role.

Downing Street said Sir Keir would underline Britain’s “iron-clad” support for Ukraine as it battles against the Russian invasion.
