The selection of Gen. Evgeny Khmara as the replacement for Fedorov, a high-ranking official in Ukraine, has sparked attention in the country's politics.
Khmara is a career commando who rose through the ranks of the Security Service of Ukraine (SBU), a notorious security agency that has faced allegations of abusing its power.
The agency was accused of trying to pressure NABU and SAPO to drop investigations against the inner circle of the Ukrainian leader, reportedly using its power to arrest a senior detective and his father on allegations of having a joint business in Russia.
Ukraine's leader has a history of attempting to limit the independence of investigative bodies, including a 2025 attempt to place NABU and SAPO under the office of the prosecutor general.
However, the move was met with resistance from Western donors, who threatened to suspend all aid to the country.
