Ukraine’s Justice Minister German Galushchenko has been suspended amid a sweeping corruption investigation into the country’s energy sector, Prime Minister Yuliia Svyrydenko announced Wednesday.

“This morning, an extraordinary session of the government was held. A decision was made to suspend German Galushchenko from performing the duties of the minister of justice,” Svyrydenko said in a statement.

The move comes as anti-corruption agencies intensify an investigation into what they describe as a “large-scale” $100 million kickback and money-laundering scheme involving senior energy officials.

Ukrainian authorities have charged seven individuals in connection with the case, which has stirred public outrage and renewed scrutiny of President Volodymyr Zelenskyy’s efforts to root out graft.

Galushchenko, who previously served as energy minister, was reportedly the subject of searches by the National Anti-Corruption Bureau (NABU) on Monday.

NABU and the Special Anti-Corruption Prosecutor’s Office (SAP) said Tuesday they have also implicated a former deputy prime minister, identified by the nickname “Che Guevara,” in the scheme, alleging evidence of illicit cash transfers totaling more than $1.2 million.

Deputy Justice Minister for European Integration Issues Lyudmila Suhak will temporarily assume Galushchenko’s duties.
