The world's largest accountancy firm, Deloitte, helped falsify documents to hide Roman Abramovich's wealth and evade tax, a joint investigation by BBC Panorama and the Bureau of Investigative Journalism has found. Assets including superyachts, mansions and private jets worth $672 million were made to disappear from the sanctioned Russian oligarch's company accounts, with the firm also appearing to advise on a scheme to evade a huge tax bill through document falsification.
The investigation, published on 12 October 2026, uncovered evidence that accounts signed off by Deloitte in Cyprus omitted assets worth $672 million (approximately £508 million). Barrister Andrew Mitchell KC, an expert in financial services law, told the BBC that the evidence showed the scheme was "straightforward" tax evasion and that "it couldn't be more blatant."
Roman Abramovich's lawyers denied that he evaded tax or concealed his fortune. They said the BBC provided no evidence that he knew about, authorised or directed the falsification of any document, and argued it was legitimate to rely on advice from professionals. Deloitte Cyprus said it "acts in compliance with applicable laws."
Abramovich, the former owner of Chelsea Football Club, was sanctioned by the UK government in 2022 after Russia's full-scale invasion of Ukraine, forcing him to sell the club. He has been reported to be living in Turkey, which did not apply sanctions. In the Channel Island of Jersey, £5.4 billion of his assets remain frozen, and a criminal investigation has been ongoing for four years. His lawyers said he denies the allegations in that investigation and claimed it was "undertaken for political purposes."
The findings raise serious questions about the integrity of professional advisers working for sanctioned individuals and about the enforcement of sanctions and tax laws.
Analysis
Why This Matters
- The investigation exposes potential failures in the global financial system to prevent tax evasion and sanctions-busting by wealthy individuals.
- It raises questions about the conduct of a major accounting firm and the effectiveness of self-regulation in the professional services industry.
- The case may lead to further scrutiny of how Western professional firms interact with sanctioned Russian oligarchs and their assets.
Background
Roman Abramovich was one of the most prominent Russian oligarchs in the UK, known for his ownership of Chelsea Football Club from 2003 until his forced sale in 2022 after being sanctioned as an associate of President Vladimir Putin following the full-scale invasion of Ukraine. Deloitte is one of the "Big Four" global accounting firms, with operations worldwide including in Cyprus, a jurisdiction known for its financial services industry. The BBC Panorama investigation, conducted jointly with the Bureau of Investigative Journalism, examined documents and accounts related to Abramovich's business empire.
Key Perspectives
Deloitte Cyprus: The firm stated it "acts in compliance with applicable laws," without directly addressing the specific allegations of document falsification.
Roman Abramovich's legal representatives: They deny that Abramovich evaded tax or concealed his fortune, asserting there is no evidence he knew about or directed any falsification. They maintain it was reasonable to rely on professional advice.
Investigators and legal experts: Barrister Andrew Mitchell KC described the scheme as blatant tax evasion. The ongoing criminal investigation in Jersey, which has frozen £5.4 billion of Abramovich's assets, represents an active law enforcement response.
What to Watch
- The outcome of the Jersey criminal investigation, now in its fourth year, and whether it leads to charges or asset recovery.
- Potential regulatory action against Deloitte Cyprus by accounting oversight bodies or by UK authorities given the connection to a sanctioned individual.
- Whether other jurisdictions, including the UK or EU, open their own investigations into the conduct of professional advisers linked to Abramovich's affairs.
