National Anti-corruption Bureau of Ukraine (NABU) Director Artem Sytnyk has expressed amazement at accusations against his agency for failing to achieve results, saying the campaign against NABU is intended to nullify the results of the agency.

"No one is settling personal scores. I never name individuals… This is just normal work, which we must do," Sytnyk said at a meeting of the parliament's committee on preventing and combating corruption on Wednesday.

Sytnyk said he was surprised by charges that NABU has achieved no results, noting public perception of results means guilty court verdicts, and Ukraine's anti-corruption court is still in the process of creation.

"It's horrible to hear that cases are falling apart in the courts… In order to claim that a case is falling apart, a prosecutor, a lawyer needs to read it first… Cases are not falling apart. Cases are simply frozen. This is why we need the high anti-corruption court to be created," he said.

The NABU director dubbed rallies and campaigns against his agency and parliament's anti-corruption committee "brutal."

Sytnyk again said he is ready for NABU to be audited. He said only an audit could evaluate the agency.

"What we see now are attempts to destroy everything we have achieved… Time is passing, fears are growing," Sytnyk said.
