Zelenskyy's top diplomat a surprise cabinet resignation

A spate of resignations from Ukraine's government came with one major surprise: the departure of Dmytro Kuleba, the career diplomat who courted western support for his country's defence as its tireless foreign minister.

- 

Ahead of a major overhaul, six cabinet ministers have resigned, sending handwritten notes to parliament that offered little explanation for their decisions.

Kuleba was the last to leave Wednesday, though his exit has not been formally sanctioned by parliament.

Kuleba, 43, became Ukraine's most recognizable representative abroad-second only to President Volodymyr Zelenskyy - and built close relationships with U.S. Secretary of State Antony Blinken and European leaders.

Both before and after the fullscale Russian invasion of early 2022, he argued on multiple trips abroad that the outcome of the conflict was a test of western resolve to push back autocracy.
