Ukraine's Presidential Administration has denied any involvement in the falsification of e-declaration checks, saying it has no way to influence the National Agency on Corruption Prevention (NACP).

"We have no way to influence the work of NACP. Statements made by [NACP employee] Hanna Solomatina] should be viewed within the context of her working and personnel ties with NACP leaders," the Presidential Administration told the Kyiv-based Interfax-Ukraine news agency on Tuesday.

The administration's press service said Ukrainian President Petro Poroshenko is counting on the effectiveness of newly-created law-enforcement agencies and "categorically opposes fighting between these agencies, which has increased in recent days to the detriment of the electorate's interests."

NACP's chief of financial control and lifestyle monitoring Hanna Solomatina earlier in the day has said e-declaration checks are being falsified. She has asked anti-corruption agencies to look into unlawful actions and called for removing NACP head Natalia Korchak during the investigation.

Solomatina also said that NACP is not an independent agency, but is controlled by authorities.

"The so-called NACP 'watcher' at the Presidential Administration summoned me and two NACP colleagues in September and offered to review NACP draft decisions before they were adopted. I refused… And later, on September 25, NACP's chief by herself, without agreeing with colleagues, signed an unlawful order that my department addressed to someone loyal to Korchak. Since that time, all documents from my department required approval by this 'controller,' Solomatin said during a press briefing in Kyiv on Tuesday.
