Boris Johnson has offered battle training for tens of thousands of Ukrainian troops during an unannounced visit to Kyiv for talks with president Volodymyr Zelensky.
The prime minister’s second trip to the war-torn country came a day after a joint visit by French president Emmanuel Macron, German chancellor Olaf Scholz and Italian PM Mario Draghi and two months after his own first meeting with Zelensky in the Ukrainian capital.
