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

What the report says

BBC World News, working with the Bureau of Investigative Journalism, says a new Panorama investigation found that advisers linked to Roman Abramovich helped conceal his wealth, with Deloitte allegedly involved in falsifying documents. The report says the documents were backdated and used to obscure assets and avoid tax. Abramovich denies wrongdoing.

The BBC says investigators reviewed hundreds of documents as part of the inquiry. The programme frames the case as a look at how a major international accountancy firm and other advisers may have assisted in keeping ownership structures and wealth hidden from scrutiny. The BBC did not provide a detailed public accounting in the snippet of exactly how the records were altered, but it presented the material as evidence of a wider effort to disguise the billionaire’s finances.

The allegation matters because it touches on tax compliance, professional responsibility and the role large advisory firms can play in managing the wealth of ultra-rich clients. Abramovich is a prominent Russian businessman whose finances have long drawn public attention, and the report adds to broader concerns about opaque offshore structures and document manipulation used to conceal assets. Background context: such investigations often focus on shell companies, trust arrangements and recordkeeping practices, though specific legal conclusions would depend on authorities and courts.
