A joint investigation in 2023 resulted in the arrest of the head of Ukraine's Supreme Court, Vsevolod Kniaziev, in connection with a $3m (£2.4m; €2.9m) bribe.

Ukraine’s anti-corruption bodies said on Saturday they had uncovered a major graft scheme that procured military drones and signal jamming systems at inflated prices, two days after the agencies’ independence was restored following major protests.

Four Ukrainians have been detained in an investigation of "large-scale" government corruption, including a parliament member, two anti-corruption agencies said.
