Alisher Usmanov, who has sponsorship links to Everton FC, has had his assets frozen as part of sanctions enforced by the European Union (EU) in response to Russiaâ€™s invasion of Ukraine.
The Uzbek-born billionaireâ€™s USM Holdings sponsors Evertonâ€™s training ground, with an initial 5-year deal announced back in 2017.
It also has an option on naming rights for the Toffeesâ€™ new stadium, a deal worth Â£30 million (about $40.2 million) to the club.
The EU said in a statement that its Council had â€œadded 26 persons and one entity to the list of persons, entities and bodies subject to restrictive measures in respect of actions undermining or threatening the territorial integrity, sovereignty and independence of Ukraine.â€
And a regulation update in the Official Journal of the European Union said Usmanov, a long-time business partner of Everton owner Farhad Moshiri, was among the 26.
The statement added that restrictive measures included â€œan asset freeze and a prohibition from making funds available to the listed individuals and entitiesâ€.
Also, a travel ban is applicable to the listed persons and prevents them from entering or transiting through EU territory.
The regulation update describes Usmanov as a â€œpro-Kremlin oligarch with particularly close ties to Russian President Vladimir Putin.â€
It added: â€œHe has been referred to as one of Vladimir Putinâ€™s favourite oligarchs.
â€œHeâ€™s considered to be one of Russiaâ€™s businessmen-officials, who were entrusted with servicing financial flows, but their positions depend on the will of the president.â€
