Ukraine's intelligence chief: We have people in offices closest to Putin

He made the statement in an interview with Reuters.

He noted that he had accurately predicted the full-scale Russian invasion before it began.

"Who turned out to be right? Us. We have our own sources. In the closest offices (to Putin), so to say. This is why we usually know what's going on," Budanov said.

Also, according to his information, the founder of Wagner PMC, Yevgeny Prigozhin, has significant support in Russia.

• Earlier, Budanov said that if Prigozhin and Wagner PMC reached Moscow, he would show the Russians an empty Kremlin. "If Prigozhin had implemented his original plan, Russia would have been divided into at least two parts... If Prigozhin had entered the empty Kremlin that day, he would have shown the public that the Kremlin was empty. There were no ministers. There are no real high-ranking officials there. They have all fled, and he would have demonstrated that there is no power in Russia now," said the intelligence chief.
