"This means that a political scandal - a corruption scandal - is widening in Ukraine," Peskov told Rossiya 1 journalist Pavel Zarubin.
The situation, given the mounting graft scandal shaking up Ukraine, will be very difficult, the Kremlin press secretary said.
"The corruption scandal, which, in fact, is now shaking the political system of this country in all directions," Peskov said, adding that severe political fallout awaits the authorities in Kiev due to the corruption scandal, but it is impossible to predict what these consequences will be.
Earlier in the day, Ukraine’s National Anti-Corruption Bureau (NABU) confirmed that it was conducting searches of the office of Andriy Yermak, Volodymyr Zelensky’s chief of staff, as part of a deepening corruption probe targeting senior officials.
