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.

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.

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