A power player in Russia since the late 1990s, the oligarch is a former member of parliament and was the governor of the Chukotka region from 2000 to 2008.
As one of Russia’s richest people, he made his fortune buying up Russian oil assets during the privatization wave that followed the end of the Soviet Union. Before he was sanctioned in March 2022, his net worth was reported to be $12.3 billion.
He is perhaps best known internationally as the owner of Chelsea Football Club, which he announced that he would sell in the wake of Russia’s full-scale invasion of Ukraine. He has vehemently denied allegations that he is close to Russian President Vladimir Putin and his government.
