“Only now we are beginning to understand that in fact in previous years, Ukraine has lost part of its political sovereignty to please political ambitions,” RIA Novosti quoted him as saying.

Batenko added that in fact there are "all signs of a crime and state treason."

"The deputy group" For the Future "appeals to the head of the Verkhovna Rada to immediately create a temporary investigative commission on these facts," he said.

Earlier, Ukrainska Pravda, citing sources, reported that the Prosecutor General’s Office of Ukraine launched an investigation into a criminal case of high treason and abuse of power in connection with the publication of audio recordings of conversations, allegedly by ex-president Petro Poroshenko and former US vice president Joe Biden.

Ukrainian deputy Andrei Derkach during a press conference published "records of telephone conversations" with votes similar to those of Poroshenko and Biden and, as he said, "testifying to the facts of international corruption and high treason at the highest state level."

They showed several fragments of audio recordings, one of which concerned the dismissal of Viktor Shokin from the post of Prosecutor General of Ukraine in 2016, allegedly at the request of Biden.

In exchange for this, he allegedly promised Poroshenko to allocate $ 1 billion to Ukraine.
