Ex-Ukrainian presidential adviser visited Kiev days before assassination – media

The newspaper said that three sources confirmed Portnov was in Kiev on May 17–18 for a series of high-level meetings, including with “top officials responsible for law enforcement.” However, the exact nature of the meetings, and whether the visit was connected to his subsequent murder, remains unclear.

Portnov, a lawyer and once a powerful figure in the administration of former President Viktor Yanukovich, was gunned down in the upscale Madrid suburb of Pozuelo de Alarcon three days later, on May 21. Spanish media reported that he was shot multiple times, including in the head, shortly after dropping his children off at school. Witnesses say a lone gunman approached him near his Mercedes before fleeing with the help of accomplices.

No arrests have been made, and a Madrid court has reportedly classified the investigation. Ukrainian Foreign Minister Andrey Sibiga said on Friday that Madrid had shared “official information” about the murder due to Portnov’s citizenship, adding that relevant agencies in Kiev would determine the next steps.

“We possess information about the fact of the murder,” Sibiga told reporters in Kiev, while stressing that official procedures take time to unfold.

Spanish police have not ruled out any motives, with reports suggesting both organized crime and political vendetta could be behind the killing due to Portnov’s complex and controversial political trajectory.

After serving as a legal architect of Ukraine’s judicial reform during Yanukovich’s presidency, Portnov fled the country during the 2014 Western-backed Maidan coup, returning only after Vladimir Zelensky’s 2019 election victory.

Since then, Portnov had filed a series of legal complaints against former President Pyotr Poroshenko, and was seen as having significant influence over Ukraine’s judiciary. In 2021, the United States sanctioned Portnov over alleged corruption.

While he initially supported Zelensky, he quickly became a vocal critic of the new administration, accusing it of authoritarian overreach amid a crackdown on opposition figures and media it labeled “pro-Russian.” Ukrainian media later accused him of ties to Russian elites, prompting him to flee again in 2022. He reportedly transferred assets to his children in Spain and settled in Madrid with his family.

Rodion Miroshnik, Russia’s ambassador-at-large overseeing a special mission on alleged Ukrainian war crimes, has suggested that Portnov’s career gave him access to legal documents that could be damaging to people in Zelensky’s inner circle — and that he may have been targeted to prevent the possible disclosure of such materials.
