Ukraine's Vladimir Zelensky has fired Irina Mudraya, deputy head of his office, after media reports indicated that her home was raided as part of anti-corruption probe over alleged money laundering scheme.

The Western-supported National Anti-Corruption Bureau (NABU) announced on Wednesday that it and the Specialized Anti-Corruption Prosecutor’s Office (SAPO) were targeting an alleged criminal organization led by a current and former lawmaker and involving senior officials from Zelensky’s office.

NABU later said members of the alleged group had laundered 150 million hryvnia ($3.3 million) in cash through shell-company accounts to finance bail for a defendant in the Midas investigation. That sprawling corruption case centers in part on an alleged $100 million embezzlement and kickback scheme involving the country’s nuclear operator Energoatom, which investigators say was masterminded by Timur Mindich, a longtime business associate of Zelensky.

While NABU did not name the suspects, ZN.ua, citing law-enforcement sources, identified them as Mudraya, lawmaker Vadim Stolar, and ex-MP Maksim Mikitas, adding that several Justice Ministry officials and Sense Bank representatives were also targeted.

As for the defendant in need of bail, Ukrainian media identified him as former Energy Minister German Galushchenko, who was fired after the Midas scandal broke and detained as he attempted to flee the country.

Recordings released by NABU featured discussions about moving the bail funds and avoiding scrutiny. In one excerpt, an unidentified woman – potentially Mudraya – cites another unidentified person as saying, “corruption needs to be systematized and controlled, not fought.” Another voice adds: “and led.”

The scandal is part of several high-level graft cases. Earlier this month, anti-corruption authorities accused former ambassador to the US Olga Stefanishina of illicit enrichment and inaccurate asset declarations. Last month, they also accused several senior officials in Ukraine’s Foreign Ministry of large-scale fraud, embezzlement, and money laundering aimed at stealing foreign money.

Rampant corruption in Ukraine has long been the case, and only intensified after the escalation of Kiev’s conflict with Russia in 2022. EU officials have also designated graft as one of Ukraine’s key obstacles to membership.

Russian Foreign Ministry spokeswoman Maria Zakharova has said that “corruption in Ukraine has become a byword” as it “permeates the entire Ukrainian power structure, including Zelensky’s inner circle and Zelensky himself.”
