In October 2009, Denisova was ranked 15th in the top 100 of "most influential women in Ukraine" compiled by experts for the Ukrainian magazine Focus (six places lower than non-minister and fellow Batkivshchyna member Natalia Korolevska).^[14]

Ombudsman for Human Rights in Ukraine

On 15 March 2018, the Verkhovna Rada appointed Denisova Ombudsman to head the Ukrainian Commission for Human Rights, where she led a team of human rights and constitutional lawyers.^[24][4]

In February 2019, following the Kerch Strait incident in which Russia and Ukraine's tensions had dramatically increased and the Federal Security Service had taken into custody a number of Ukrainian troops, Denisova was able to make contact with Tatyana Moskalkova, her Russian counterpart, via an impromptu meeting, and discuss the status of wounded Ukrainian prisoners of war.^[25] The latter had previously refused to meet with her after Denisova launched an official protest that she was not able to visit the Ukrainian wounded soldiers directly.^[26]

During the Russian invasion she was described as becoming "one of the leading voices of Ukraine’s suffering and outrage, appearing frequently in news coverage and producing a copious stream of social media posts"^[24] She set up a hotline for citizens to report human rights violations and requests for help. According to New York Times, "The vast majority [of calls], more than 15,000 in the first six weeks of war, were for missing people, but requests also come in for humanitarian aid and safe corridors out of besieged cities... The information from callers is fed into a database that Ms. Denisova shares with government officials and prosecutors. As such, it has become an invaluable first warning system for the gross human rights abuses occurring in the cities under assault, and in the towns and villages occupied by Russian troops."^[24] Denisova argued that Russian forces were committing genocide, citing the systematic sexual violence by Russian troops and the forcible deportation of Ukrainian children to Russia.^[24] She said that in many cases Russian soldiers had called Ukrainian women "Nazi whores" and raped them “until they can't give birth, or give birth to their children" "This suggests that they want to destroy the Ukrainian nation. And when they kill children, it also means that they do not want our nation to be in this world.”^[24]

On 31 May 2022, the Verkhovna Rada voted to dismiss her, using the provisions of Ukraine's martial law, for failing to facilitate humanitarian corridors in warzones, to prevent Ukrainians under Russian occupation from being deported to Russia, and to facilitate the protection and exchange of prisoners of war.^[27][28][29] The deputy chairman of the Rada regulatory committee said that Deputy Prime Minister Iryna Vereshchuk had had to take on most of the wartime human rights issues.^[28] An open letter from 140 activists, media professionals and lawyers criticized the rhetoric of her reports about sexual crimes by Russian forces just before her dismissal.^[30][31][27]

Some NGOs and human rights activists, including Opora, questioned the legality of her removal. The Global Alliance of National Human Rights Institutions (GANHRI) and the UN Human Rights Monitoring Mission in Ukraine (HRMMU) both criticised the procedure followed for dismissing Denisova, with HRMMU describing the dismissal as "violat[ing] international standards". As of 3 June 2022^[update], a replacement had not been appointed.^{[29][32][33][34]} In June, Ukrainska Pravda published a report alleging that journalists and the Ukrainian Prosecutor’s Office had only been able to verify some of the rapes Denisova had spoken about publicly.^[35] Additionally, the deputy chairman of Ukraine's parliament regulatory committee Pavlo Frolov said that Denisova's focus on reporting some unverified crimes had harmed Ukraine's reputation and distracted media attention from proven crimes and problems.^[36]
