Watch: How did Roman Abramovich's advisors help hide his wealth?

BBC Panorama and partners uncovered documents suggesting Deloitte, one of the world's largest accounting firms, helped falsify records to hide Roman Abramovich's wealth and evade taxes. The investigation revealed that assets worth $672 million (£508 million), including superyachts, mansions, and private jets, were made to disappear from his company accounts through backdated documents signed off by Deloitte in Cyprus. Experts like barrister Andrew Mitchell KC described this as "straightforward" tax evasion. Abramovich's lawyers deny any wrongdoing, stating he relied on professional advice and had no knowledge of or involvement in the document falsification. The findings stem from a joint investigation involving BBC Panorama and the Bureau of Investigative Journalism, based on leaked files since 2023 as part of the International Consortium of Investigative Journalists' Cyprus Confidential project.
