Exiled lawmaker Oleksandr Onyshchenko on Dec. 6 released the first of a series of audio recordings he claims prove President Petro Poroshenko and his inner circle are corrupt.

The recording was released by the strana.ua online newspaper. In the recording, Onyshchenko and lawmaker Oles Dovhiy, whom the fugitive member of parliament described as representing Poroshenko, discuss the possibility of Onyshchenko, a suspect in an embezzlement case, reaching a plea bargain with Ukrainian authorities. Onyshchenko told strana.ua that the plea bargain would be reached in exchange for him writing off Poroshenko’s alleged $50 million debt to him.
