"According to information provided by the Prosecutor General's Office (PGO) during the trial, Yanukovych de facto acted as an accomplice in the crimes committed by the Berkut. Therefore, on the basis of an absolute human right to defense, he would have to be questioned. But this question was raised by Viktor Yanukovych, not by the PGO," Serdiuk stated.
