Ukrainian President Volodymyr Zelensky has accepted the resignation of his chief of staff, Andrii Yermak, following a search of Yermak's residence by anti-corruption investigators. Yermak, a close confidant and lead negotiator with the United States, leaves his post at a critical time as Ukraine faces mounting pressure to reach a peace agreement nearly four years into the conflict with Russia. Zelensky acknowledged the risks of internal division and emphasized the importance of national unity, warning that any missteps could jeopardize Ukraine's future. Yermak's absence from the list of officials for upcoming negotiations signals a significant shift in Ukraine's diplomatic approach.
