The lawyer of the ex-president of the country Igor Golovan said that the order of delivery of the summons and the timing of the call for interrogation were “violated”.

According to him, the GDB violated Ukrainian law when summoned for questioning, therefore, "citizens have the right not to comply with illegal requirements."

Earlier, the GDB called Poroshenko for questioning on May 29 in the case of wiretapping his conversation with former US Vice President Joe Biden. 

On May 19, Verkhovna Rada deputy Andriy Derkach during a press conference published "records of telephone conversations" of persons with votes similar to those of Poroshenko and Biden.

During the press conference, several fragments of audio recordings were presented, 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, the American vice president allegedly promised Poroshenko to allocate $ 1 billion to Ukraine.
