Ukraine’s Foreign Minister Dmytro Kuleba has resigned, the speaker of parliament said Wednesday, as part of a major cabinet reshuffle.

The announcement follows the resignation of a number of other ministers in a reshuffle that comes two and a half years after the Russian invasion, according to AFP.

Kuleba, who was at the forefront of Ukrainian diplomacy during the war, is the most high-profile minister to resign.

On Tuesday, a number of cabinet ministers resigned, including the ministers of justice, strategic industries and environmental protection.
