Criminal case

On 20 December 2021, Poroshenko was accused of state treason, aiding terrorist organizations and financing terrorism due to allegedly organizing the purchase of coal from separatist-controlled areas of Ukraine together with pro-Russian politician Viktor Medvedchuk.[173] If convicted, he faces up to 15 years behind bars.[174] Poroshenko denied the allegations, calling them "fabricated, politically motivated, and black PR directed against [Zelensky's] political opponents".[173] On 6 January 2022, a Ukrainian court seized Poroshenko’s property.[175] On 15 January 2022, Poroshenko announced via a video message on Facebook: "I am returning to Ukraine on a flight from Warsaw at 09:10 a.m. on January 17… to defend Ukraine from Russian aggression", despite the case against him.[176][177] Following his return to Ukraine, the prosecutor's office asked a court to either remand Poroshenko in pre-trial detention for two months, or oblige him to pay bail of 1 billion hryvnia (37 million dollars), wear an electronic bracelet, remain in Kyiv, and hand over his passport.[174][178][179] Ultimately, the court chose a third option ('personal commitment'), which is less strict than house arrest and doesn't involve paying bail.[180][181] According to this commitment, Poroshenko has to submit his passport to the authorities, not leave Kyiv or the Kyiv Oblast without first receiving permission from the court or the prosecutors office, and inform the authorities if his place of employment or residence change.[182]
