Sir Keir Starmer has said the UK's "cast-iron" support for Ukraine will continue, as he makes a final trip to the country as prime minister, BBC reported.
He will meet Ukrainian President Volodymyr Zelensky in the capital Kyiv later on Thursday, ahead of Andy Burnham's installation as Labour leader and PM.
In comments ahead of his trip, Sir Keir said the "fortitude" of the Ukrainian people since Russia's full-scale invasion in February 2022 had "preserved the security of Europe".
