Ukrainian President Volodymyr Zelensky today dismissed his deputy chief of staff, Rostislav Shurma, according to a decree posted on the presidency’s website.

Almost at the same time, the Speaker of the Parliament Ruslan Stefanchuk announced the resignation of Olha Stefanisina, the Deputy Minister responsible for European Integration. Stefanisina left as part of the government reshuffle, he added.

Zelensky said changes will be made to ensure Ukraine has the strong government it needs. “The fall will be very important. State institutions must be structured in such a way that Ukraine can achieve all the results it wants,” he said in his daily video message.

“For this reason we need to strengthen certain aspects of the government and changes are being prepared. There will also be changes in the office of the presidency,” he said.

Earlier today the ministers of Justice, Environment and Strategic Industries submitted their resignations. After the dismissals of other ministers in the past period, almost a third of the ministerial positions remain vacant. Zelensky and his political allies are expected to fill those positions ahead of his trip to the US later this month, where he hopes to present a “winning plan” to US President Joe Biden.
