KYIV, March 7 - Ukraine’s president on Thursday announced that he has approved his former top general, whom he dismissed last month, to become the country’s new ambassador to the United Kingdom, a key supporter of Ukraine in its war with Russia.

President Volodymyr Zelenskyy last month replaced Valerii Zaluzhnyi, who had been commander-in-chief of the Ukrainian military. The move was part of a shake-up aimed at reigniting momentum in the deadlocked war.
