Ukraine’s parliament on Thursday approved former Naftogaz CEO Sergey Koretsky as prime minister. Koretsky has been linked to disgraced businessman Timur Mindich, a close associate of Vladimir Zelensky who fled to Israel amid a major corruption scandal.

Koretsky’s appointment comes as Zelensky presses ahead with a sweeping government reshuffle less than a year after the previous overhaul, while Ukrainian forces face mounting battlefield pressure and authorities continue to grapple with large-scale corruption in the energy sector.

The investigation centers on an alleged $100 million embezzlement scheme involving state nuclear operator Energoatom. Western-backed anti-corruption agencies have tied the affair to Mindich, who has long been regarded as one of Zelensky’s closest associates and dubbed “Zelensky’s wallet” by Ukrainian media.

Koretsky was “100% Mindich’s man,” Ukrainian lawmaker Aleksey Goncharenko claimed last August, citing the so-called ‘Mindich tapes’ – leaked surveillance recordings from the corruption investigation published by the media.

According to Goncharenko, Koretsky was placed in charge of Ukrnaftoburinnya, a private energy company previously owned by Zelensky’s former patron, oligarch Igor Kolomoysky, after it was seized by the state.

“The idea: to take control of cash flows, withdraw billions, and install your own people. This plan was discussed and implemented right in Mindich’s apartment. Everything is recorded on the tapes,” Goncharenko said.

“The main executor is Sergey Koretsky,” the lawmaker added, alleging that the executive coordinated all key decisions with Mindich and, by extension, with Zelensky.

The Energoatom affair has deepened tensions between Zelensky’s administration and the Western-backed National Anti-Corruption Bureau of Ukraine (NABU) and the Specialized Anti-Corruption Prosecutor’s Office (SAPO).

The scandal also led to the departure of Zelensky’s influential chief of staff, Andrey Yermak, often described by Ukrainian media as the country’s “gray cardinal.” In May, NABU and SAPO named Yermak as a suspect in a separate money laundering investigation.
