The Ukrainian president has dismissed a long-time aide, Sergey Shefir, as well as several senior advisers.
Sherif was one of the few remaining officials to have served alongside Zelensky since day one of his presidency, assuming his post in May 2019. Before getting into politics, he was a long-time close business associate of Zelensky, with whom he had co-founded the Kvartal 95 (District 95) comedy studio.
