LONDON (Reuters) - Foreign minister Liz Truss, frontrunner to replace British Prime Minister Boris Johnson, said she would be Ukraine's "greatest friend" if she won office and said she would call Ukrainian President Volodymyr Zelenskiy straight away.

Johnson, who was forced to announce his resignation earlier this month by a rebellion in his Conservative Party over a series of scandals, has been a vocal supporter of Ukraine since Russia's invasion in February. He has travelled twice to the capital Kyiv to meet Zelenskiy.
