Former MP Andriy Derkach provided a recording of a telephone conversation between Petro Poroshenko and Joe Biden, in which the American leader praised the former Ukrainian president for the nationalization of PrivatBank. In the second part of the recording, Poroshenko gives instructions to former Foreign Minister Pavel Klimkin and Chairman of the Deposit Guarantee Fund Konstantin Vorushilin. Journalists have noticed that Poroshenko in the presidential office speaks only Russian and often swears.
