People should read the article, it's short. But here's the important part:
“I am tendering my resignation from the post of the Prime Minister of Ukraine,” Denys Shmyhal wrote in a letter posted on his Telegram page.
Zelenskyy said Monday that he has offered Shmyhal’s job to 39-year-old Yuliia Svyrydenko, who is currently deputy prime minister and the country’s first female economy minister.
Svyrydenko played a key role in negotiating a U.S.–Ukraine mineral agreement. She has frequently represented Ukraine in high-level talks with Western partners, focusing on defense cooperation, economic recovery and reconstruction.
