Roman Arkadyevich Abramovich (born 24 October 1966) is a Russian business oligarch and politician. He is the former owner of Chelsea, a Premier League football club in London. He has Russian, Portuguese and Israeli citizenship. Abramovich was Governor of Chukotka Autonomous Okrug from 2000 to 2008. Abramovich, including his family and affiliated related trusts, is the 371st richest person in the world with a net worth of $9.3 billion according to Forbes and the 444th richest person in the world with a net worth of $8.56 billion according to Bloomberg L.P. He is the fifth-richest person with Israeli citizenship. Abramovich enriched himself in the loans for shares scheme by Boris Yeltsin following the dissolution of the Soviet Union, acquiring a stake in Sibneft in partnership with Boris Berezovsky for approximately $100 million in 1995, well below market value. In 2005, he sold the stake to the Russian government under Vladimir Putin for $13 billion. Like all Russian oligarchs, Abramovich is considered to have a good relationship with Putin. As a result of these alleged relations, he has been subject to sanctions following the 2022 Russian invasion of Ukraine. Abramovich allegedly now spends most of his time in Turkey. Abramovich's assets are held in a web of companies; much of his assets are based in Jersey.
