He denied having any contact with Russian intelligence officers and dismissed the idea that he could be in league with the Kremlin as "stupid," given he was placed under Russian sanctions in 2018.
Although he says he wants Ukraine to be independent from Russia as well as the West, Murayev has promoted some views that align with the Kremlin's narratives on Ukraine.
The British foreign ministry declined to provide evidence to back its accusations. In a message to Reuters, Mykhailo Podolyak, a Ukrainian adviser to the presidential office, said there was doubt among Ukrainians as to whether Murayev was "too ridiculous a figure" to be the Kremlin's pick to lead Ukraine.
