It is because of this nexus between Poroshenko—who claims the role of leader of opposition and patriotic forces—and the pro-Russian and 'toxic' Medvedchuk that the political confrontation between the current and former presidents of Ukraine has reached a new point.
It started to transpire as far back as February 2021, when the Council of National Security and Defence of Ukraine, in a first, introduced sanctions against Ukrainian nationals on suspicion of financing terrorism. The said nationals were Victor Medvedchuk and Taras Kozak, his political ally, believed to be hiding from prosecution abroad. As a result, three TV channels associated with Medvedchuk—112 Ukraine, NewsOne, and ZIK—were taken off air.
The legally murky sanctions were generally welcomed by Ukrainian society, including in the patriotic circles. They were a booster injection into Volodymyr Zelenskyy's ratings, which were falling at the time against the backdrop of numerous scandals—take, for instance, the appointment of Oleh Tatarov, accused of involvement in crackdown on Euromaidan, as deputy Head of the Presidential Office. The ban on Medvedchuk's TV channels and, later, his house arrest did not lead to mass protests.
Enter Poroshenko's terrorism charges—which, importantly, are related to those of Medvedchuk and make for imposing personal sanctions. Ukrainians are supposed to believe that the two were at least associates, if not 'partners', during the fifth president's term.
