The recent sweeping search within Ukraine’s government has dealt a significant blow to its leadership, potentially complicating their negotiation efforts as the nation faces intense pressure from the United States to finalize a peace agreement nearly four years after Russia’s full-scale invasion.

Yermak, a steadfast ally of President Zelenskyy, has faced ongoing calls for his removal, but Zelenskyy has consistently resisted such demands.

Addressing the contentious issue of Yermak’s prolonged association with him, Zelenskyy emphasized that Russia is keenly observing for any missteps that could jeopardize the fragile and tense peace talks.

“We cannot afford to retreat or engage in internal disputes. Losing our unity means risking everything — our identity, our nation, and our future,” Zelenskyy declared. “It is imperative that we remain united and steadfast. There is no alternative. We won’t have another Ukraine.”

He further stressed, “To maintain our internal resilience, we must focus solely on defending Ukraine. I want to eliminate any doubts about our commitment, which is why we are making today’s decisions.”

In his nightly address, Zelenskyy announced that he was “resetting” the presidential office. He said Yermak had submitted his resignation and that he would begin consultations Saturday to appoint a new chief of staff.

Yermak’s name did not appear on a list of officials that Zelenskyy said would make up the Ukrainian delegation for the next round of negotiations with the United States.

The delegation will now be jointly lead by Andrii Hnatov, the head of Ukraine’s armed forces; Andrii Sybiha, Ukraine’s foreign minister; and Rustem Umerov, head of Ukraine’s security council, Zelenskyy said. He said negotiations would happen “soon.”

Two national agencies fighting corruption in Ukraine said their search targeted Yermak. Oleksii Tkachuk, a spokesperson for Yermak, said the anti-graft agencies had not served Yermak a notice of suspicion, meaning he was not a suspect in an investigation. Yermak was not told what the searches related to, Tkachuk said.

Yermak confirmed the search of his apartment inside the presidential compound in downtown Kyiv, where checkpoints limit public access. Media reports said Yermak’s office was also searched, but investigators declined to comment on that.

It was not clear where Zelenskyy or Yermak were at the time of the morning raid.

“The investigators are facing no obstacles,” Yermak wrote on the messaging app Telegram. He said he was cooperating fully with them and that his lawyers were present.

In an interview Thursday with The Atlantic, Yermak said that as long as Zelensky is president, “no one should count on us giving up territory. He will not sign away territory.”

Ukraine, he said, is prepared to discuss only the question of what land each side controls, as indicated by the location of the front lines.

“All we can realistically talk about right now is really to define the line of contact,” Yermak said.

The National Anti-Corruption Bureau of Ukraine and the Specialized Anti-Corruption Prosecutor’s Office are leading a major investigation into a $150 million energy sector scandal involving top Ukrainian officials that has dominated domestic headlines in recent weeks.

It was not clear if the searches were connected to the case, and a spokesperson for the NABU, Anton Tatarnikov, declined to comment, citing legal restrictions on revealing details on an ongoing probe.

The head of Ukraine’s parliamentary anti-corruption committee, Anastasiia Radina, said on social media that Yermak’s resignation was “better late than never.”

Mykyta Porturaev, a politician with Zelenskyy’s party who last week called for Yermak’s resignation and for a cross-party government to be established, said the anti-corruption raid deepened Ukraine’s political crisis.

Yermak “definitely had political responsibility,” Porturaev told The Associated Press. “Of course he had to go.”

A spokesperson for the European Commission, Guillaume Mercier, told Ukrainian news outlet Radio Svoboda on Friday that they were following developments closely and that the searches showed that Ukraine’s anti-corruption agencies were working. He said fighting corruption was central to the country’s European Union accession.

Investigators suspect that Tymur Mindich, a one-time business partner of Zelenskyy, was the plot’s mastermind. Mindich has fled the country, with any criminal proceedings against him likely to be carried out in absentia. Two top government ministers have resigned in the scandal.

Two of Yermak’s former deputies — Oleh Tatarov and Rostyslav Shurma — left the government in 2024 after watchdogs investigated them for financial wrongdoing. A third deputy, Andrii Smyrnov, was investigated for bribes and other wrongdoing but still works for Yermak.

Political Turmoil for Zelenskyy

The scandal has heaped more problems on Zelenskyy as he seeks continued Western support for Ukraine’s war effort and tries to ensure continued foreign funding. The European Union, which Ukraine wants to join, has told Zelenskyy he must crack down on graft.

Zelenskyy faced an unprecedented rebellion from his own politicians earlier this month after investigators published details of their energy sector investigation.

Although Yermak was not accused of any wrongdoing, several senior politicians in Zelenskyy’s party said Yermak should take responsibility for the debacle in order to restore public trust. Some said that if Zelenskyy didn’t fire him, the party could split, threatening the president’s parliamentary majority. But Zelenskyy defied them.

Zelenskyy urged Ukrainians to unite and “stop the political games” in light of the US pressure to reach a settlement with Russia.

Yermak met Zelenskyy over 15 years ago when he was a lawyer venturing into the TV production business and Zelenskyy was a famous Ukrainian comedian and actor.

He oversaw foreign affairs as part of Zelenskyy’s first presidential team and was promoted to chief of staff in February 2020.

Yermak has accompanied Zelenskyy on every trip abroad since Russia’s invasion in February 2022, and the president’s trust in him has made Yermak’s power appear almost untouchable.

Domestically, officials describe Yermak as Zelenskyy’s gatekeeper, and he is widely believed to have chosen all top government appointees, including prime ministers and ministers.
