Multiple Ukrainian government ministers, including Foreign Minister Dmytro Kuleba, have submitted letters of resignation to the country's parliament.

Ukrainian media are reporting that President Volodymyr Zelenskyy will carry out a large-scale Cabinet reshuffle shortly.

The Speaker of Ukraine's Parliament, Ruslan Stefanchuk, revealed on social media on Wednesday that Kuleba tendered his resignation.

Kuleba has overseen diplomatic efforts to seek international support for Ukraine since the start of Russia's invasion in 2022.

Other government ministers, including Deputy Prime Minister Iryna Vereshchuk, are also expected to step down.

Zelenskyy said in a video message on Tuesday that Ukraine must boost defense production, advance work with NATO and counter Russian propaganda. He added, "Now is the time to give new strength to Ukraine's governmental institutions," and that "Autumn will be extremely important."

Ukraine is seeking a second peace summit in November this year, when the United States holds its presidential election.

Zelenskyy apparently wants to revamp his administration so that the war can be ended in a way that would be of advantage to Ukraine.
