She denies the allegations.For critics of President Volodymyr Zelensky, the timing of the case has reinforced broader concerns about how his administration handles senior officials accused of corruption.Opposition lawmaker Yaroslav Yurchyshyn argued that Stefanishyna remained in high office despite longstanding allegations because loyalty, rather than integrity, is the president's overriding criterion for key appointments."The main issue is the Zelensky team's reluctance to bring in people from outside his inner circle," Yurchyshyn told the Kyiv Independent. "Loyalty takes precedence over common-sense logic."He argued that the authorities also believe they can bring anti-corruption institutions under control and shield Zelensky's close allies from prosecution.The Kyiv Independent has requested comments from Stefanishyna and the President's Office and will publish their responses once they are received.Yanukovych eraStefanishyna, 40, has degrees in international law, English translation, and finance.She has been involved in European integration since she worked at the Justice Ministry under pro-Western President Viktor Yushchenko in the late 2000s.When Yushchenko was voted out in favor of pro-Russian President Viktor Yanukovych, she kept her seat, being later promoted to deputy head and then head of the Justice Ministry's department for international law and European integration.Yanukovych was ousted by the 2014 EuroMaidan Revolution.Olena Lukash, justice minister from 2013 to 2014, and Stefanishyna were charged in 2019 with embezzlement allegedly carried out during Yanukovych's presidency.President Vladimir Putin of Russia (R) and then-President Viktor Yanukovych (L) attend a Russian-Ukrainian summit in Moscow, Russia, on Dec. 17, 2013.

Should that have given the authorities a sign?"European integration portfolioFrom 2017 to 2019, Stefanishyna also worked as the head of the government office responsible for European integration.In the 2019 parliamentary election, Stefanishyna unsuccessfully ran on the list of then-Prime Minister Volodymyr Groysman's party.Later, Stefanishyna served as deputy prime minister for European integration from 2020 to 2025 and as justice minister from 2024 to 2025.Stefanishyna was likely put in charge of European integration because she already had vast experience in the area, according to Yurchyshyn.Then-Ukrainian Deputy Prime Minister for European and Euro-Atlantic Integration Olha Stefanishyna (L) and Spanish Foreign Affairs Minister José Manuel Albares Bueno (R) in Brussels, Belgium, on Sept. 19, 2023.

"I've heard positive feedback from both European diplomats and Ukrainian journalists who cover European integration."Yurchyshyn admitted that she had been effective but argued that she was involved in blocking some reforms in the interests of Zelensky's former Chief of Staff, Andriy Yermak.
