Roman Abramovich has been sanctioned by the UK government as part of attempts to crackdown on wealthy Russians with assets in the country.
The Chelsea Football Club owner is one of seven more Russian oligarchs who have had sanctions placed on them by ministers on Thursday.
Last week, Mr Abramovich announced that he intends to sell Chelsea after almost 20 years of ownership, with net proceeds from the sale to be donated to “all victims of the war in Ukraine”.
In a statement, he said the decision is “in the best interest of the club” amid Russia’s invasion of Ukraine.
The sanctions will come into force before the sale of the football club, estimated to be worth around £3bn, is able to take place.
The government has now sanctioned over 200 individuals and entities.
