Mayor of London Sadiq Khan has appeared to suggest that Oligarchs, such as Roman Abramovich, have used businesses, like football clubs, to launder money.
The claims come amid greater scrutiny of the ownership of football clubs after sanctions were imposed on Blues owner Abramovich by the British government.
The billionaire has had his assets frozen in the UK in the wake of Russia's ongoing invasion of Ukraine, although he continues to deny any links to president Vladimir Putin.
