The political architecture of wartime Ukraine rests on a singular, uncomfortable reality. While Volodymyr Zelenskyy is the voice and face of the resistance, the machinery of the state is operated almost exclusively by Andriy Yermak. To describe him as a Chief of Staff is to fundamentally misunderstand his reach. He is the gatekeeper, the diplomat, and the enforcer. In the halls of the Bankova—the presidential administration building—he has constructed a vertical of power so absolute that it has begun to trigger alarms from Washington to Brussels. The recent wave of scrutiny regarding his influence and the corruption allegations surrounding his circle isn't just about missing funds. It is about the survival of Ukrainian democracy under the pressures of total war.
The Architect of the Parallel State
Andriy Yermak did not rise through the traditional ranks of Ukrainian politics. A former entertainment lawyer and film producer, he entered the inner circle not as a strategist, but as a fixer. His power is derived entirely from his proximity to the President. In a country where the line between institutional authority and personal loyalty has always been thin, Yermak has erased it entirely.
He manages the most sensitive portfolios. Whether it is negotiating the Grain Initiative, securing Western weapons systems, or managing the complex "Peace Formula" summits, Yermak is the lead. This consolidation has marginalized the Ministry of Foreign Affairs and the Cabinet of Ministers. Career diplomats now find themselves sidelined by a man who holds no elected office and answers to no one but the President.
This centralization is sold as a wartime necessity. During an invasion, the argument goes, command must be streamlined. Decisions must be made in minutes, not through months of parliamentary debate. But the "temporary" nature of this power is starting to look permanent. The concern among civil society in Kyiv is that the emergency structures built to fight Russia are being repurposed to insulate the presidency from domestic accountability.
The Corruption Narrative and the Oleg Tatarov Factor
You cannot talk about Yermak without talking about Oleg Tatarov. As a deputy head of the Office of the President, Tatarov is responsible for overseeing law enforcement agencies. He is also a lightning rod for scandal. Tatarov was a high-ranking official in the Ministry of Internal Affairs under the pro-Russian President Viktor Yanukovych, and he has been the subject of numerous anti-corruption investigations that seemed to vanish into the ether once they reached the Bankova.
The protection afforded to Tatarov is seen by many as proof of Yermak’s ultimate priority. Maintaining control over the police and the courts is more important than the optics of reform. For Western donors, this is the sticking point. The U.S. and the EU are pouring billions into Ukraine with the expectation that the country is moving toward the rule of law. When major figures linked to the President’s office are shielded from prosecution, it creates a friction that threatens the long-term flow of aid.
The corruption in question isn't always the stereotypical bag of cash. It is more sophisticated. It involves the control of state-owned enterprises, the manipulation of the energy market, and the strategic placement of loyalists in "independent" regulatory bodies. By controlling the personnel, Yermak controls the outcomes.
Diplomacy in the Dark
Yermak’s foray into high-level international relations has been a double-edged sword. On one hand, his direct line to National Security Advisor Jake Sullivan and other world leaders has expedited critical military aid. He speaks the language of results. He is not a man of pleasantries; he is a man of demands.
However, this "back-channel" diplomacy creates a lack of transparency. When the President’s Chief of Staff is the one negotiating security guarantees, the parliamentary oversight committee is left in the dark. This creates a dangerous precedent. If the war ends with a negotiated settlement, the terms of that peace will likely be brokered by Yermak. Without a broader institutional consensus, any deal he strikes could be viewed as illegitimate by the Ukrainian public, leading to internal instability just as the external threat subsides.
The Successor Myth
For a time, the Kyiv rumor mill suggested Yermak was being groomed as a successor. That talk has cooled, replaced by a more cynical realization. Yermak has no interest in being the face of the country. Being the President involves the tedious theater of campaigning and the burden of public popularity. Yermak prefers the shadows where the real levers are.
He has spent years systematically removing anyone who could challenge his influence. Former Prime Ministers, former heads of the SBU (Security Service of Ukraine), and even former commanders-in-chief like Valerii Zaluzhnyi have found themselves on the outside after clashing with the Bankova. The removal of Zaluzhnyi, in particular, was seen as a move to eliminate a potential political rival to Zelenskyy, a move orchestrated by the man who manages the President’s political risks.
The Cost of Consolidation
The irony of the Yermak era is that the very efficiency he brings to the table is the biggest threat to Ukraine’s European aspirations. The European Union is not looking for a "strongman" efficiency. They are looking for institutional resilience. They want a Ukraine where the system works regardless of who is sitting in the Chief of Staff’s chair.
Currently, the system is Yermak. If he were to disappear tomorrow, the entire administrative structure of the country would likely seize up. That is not a sign of a healthy state; it is a sign of a captured one.
The Resistance from Within
Despite the consolidation of power, Ukraine’s civil society remains vibrant and vocal. Investigative outlets like Ukrainska Pravda and anti-corruption NGOs continue to dig into the procurement scandals and the wealth of Yermak’s associates. They are the final check on an administration that has largely silenced the political opposition under the banner of national unity.
The pressure is mounting. As the war enters a grueling war of attrition, the public's patience for "wartime exceptions" is wearing thin. People are beginning to ask why their sons are dying at the front while certain figures in Kyiv seem to be getting wealthier and more entrenched. The "corruption" charged against Yermak’s circle isn't just a legal issue; it's a morale issue.
A Choice of Legacies
Zelenskyy’s legacy will be defined by his courage during the first weeks of the invasion. But his long-term impact on Ukraine will be defined by whether he can dismantle the patronage system he helped Yermak build. History shows that power concentrated in a vacuum rarely gives itself up voluntarily.
The Western allies find themselves in a bind. They cannot publicly criticize Yermak too harshly without undermining the war effort, but they cannot ignore him without betraying their own democratic principles. They are effectively subsidizing a government that is becoming increasingly centralized and opaque.
The path forward requires a brutal decoupling of personal loyalty from state function. Ukraine needs a functioning Ministry of Justice, an empowered Prosecutor General, and a Parliament that does more than rubber-stamp decrees from the Bankova. If the price of victory over Russia is the birth of a new autocracy at home, many will wonder what the fight was for.
Control is a drug. In a war zone, it feels like medicine. But when the fever breaks, the patient often finds they are addicted to the cure. Andriy Yermak has made himself indispensable to the President, but in doing so, he has made himself a liability to the nation’s future. The "fixer" has reached the limits of what can be fixed with a phone call and a threat. Now, the law must be allowed to do the work that backroom deals cannot.
