Ukraine's prosecutor general said on Monday he had offered his resignation citing political reasons, in the latest sign of ​disunity in the senior ranks of the Ukrainian ruling ‌elite."This is a political decision, and I have made it consciously. I do not want the position of Prosecutor General to be used as ​an instrument of political confrontation," Ruslan Kravchenko said in ​a statement on Telegram late on Monday, without elaborating.Mr Kravchenko ⁠thanked president Volodymyr Zelensky and Ukraine's parliament, the Verkhovna Rada, ​and asked them to accept his resignation.Ukraine's anti-graft agencies said last week they had uncovered a criminal organisation dealing with fraudulent call centres which was allegedly arranged by an official within ​the Prosecutor General's Office.(AFP/Getty)Mr Kravchenko has denied he was involved in ​the alleged scheme. "My position regarding the accusations remains unchanged," he said in ‌his ⁠Telegram post.Mr Kravchenko's resignation offer follows other changes among top officials in Ukraine as it continues to battle Russia, which launched a full-scale invasion in February 2022.In July, Mr Zelensky endorsed the head of state energy ​company Naftogaz, Sergii ​Koretskyi, as ⁠Ukraine's new prime minister, following the resignation of Yulia Svyrydenko.Ms Svyrydenko's year in office coincided with a ​corruption scandal involving senior figures. Although she was ​not ⁠implicated, critics said she failed to take sufficient action to clean house.Mr Zelensky also in July replaced popular defence minister Mykhailo Fedorov just six ⁠months ​after he had been appointed. Mr Fedorov was ​a strong advocate for military reform but clashed with senior generals over strategy ​and procurement.
