Cyprus has stripped Kremlin-friendly Russian billionaire Oleg Deripaska and two other Russian nationals of Cypriot passports after admitting flaws in its citizenship-for-investment program, Cyprus’ Politis newspaper reported Wednesday.

Cyprus said this month it had started a process to strip 26 individuals of citizenship they received under a secretive passports-for-investment scheme. Sources on the Mediterranean island had told Reuters its list of individuals to lose passports included nine Russians.

Politis named Deripaska, his son and his daughter among those whose Cypriot passports were rescinded.

Vladimir Stolyarenko and Alexander Bondarenko, former executives whom Russian authorities placed on an international wanted list on fraud charges, were also listed in the Politis report.

Deripaska’s spokesperson said that Cyprus has not officially informed him that it rescinded his citizenship, the state-run TASS news agency reported.

Cyprus introduced a citizenship-for-investment plan in 2013. Under the program, foreigners who invest at least $2.2 million into the Cypriot economy can buy a passport and visa-free travel throughout the European Union.

In the five years from the beginning of the citizenship scheme to 2018, the Cypriot government approved 1,864 citizenship applications. Including family members, the number was more than 3,200, and is close to 4,000 today.
