On Tuesday, the Verkhovna Rada, Ukraine's parliament, approved Oleksii Reznikov's resignation as defense minister.
The decision was approved after 327 members voted for the decision.
President Volodymyr Zelensky announced dismissing Reznikov, Sunday, before the minister submitted his resignation to the Ukrainian parliament on Monday.
According to Zhelezniak, Rustem Umerov, the former chairperson of Ukraine's State Property Fund, was chosen by Zelensky to replace Reznikov as the defense minister.
Unerov will be appointed tomorrow.
Reznikov held the post of Defense Minister since November 2021 which marked the start of Russia's military operations in Ukraine.
He played a vital role in managing military aid from foreign allies.
However, Reznikov received a huge backlash after several scandals related to the procurement of equipment and supplies for Ukrainian soldiers.
In August, Ukrainian media Dzerkalo Tyzhnia reported that the Defense Ministry spent $33 million on "winter" clothing for the military from a Turkish company in September.
The Defense Ministry and Reznikov also faced scrutiny in January when Ukrainian media discovered a major issue with food supply procurement for soldiers.
Therefore, Ukrainian media reported in February that Zelensky had decided to dismiss Reznikov.
