Deloitte Cyprus Accused of Helping Abramovich Hide $672 Million

Leaked files allege that Deloitte Cyprus signed off replacement accounts that removed about $672 million of mansions, yachts and jets from a company linked to sanctioned Russian billionaire Roman Abramovich, in a project published on October 12, 2026. Deloitte Cyprus denies breaking any law, and Abramovich’s lawyers deny he evaded tax or concealed his wealth.

The accusation rests on leaked documents, not on a court ruling or a regulatory finding. Cyprus police opened an investigation on October 21, and the country’s audit oversight board said it is acting, but no body has yet found against the firm.

For auditors and finance teams, the case tests a basic question: what a signature on accounts is worth when the paperwork behind it can be backdated. The events date to 2003 to 2006, yet police have said the passage of time does not remove the legal basis for an inquiry.

What the Deloitte Cyprus leak shows

The material comes from Cyprus Confidential, a project built on more than 500,000 documents leaked to the International Consortium of Investigative Journalists and analysed with media partners. The project says the files include more than 1,000 documents that were backdated and rubber-stamped between 1999 and 2013.

The $672 million figure relates to one company, Amiscan Investments, a Cypriot entity in the Abramovich structure. Draft accounts circulated by Deloitte in 2005 listed more than $600 million of assets, including a $38 million estate in Sussex, an $8 million London flat, a French château, helicopters, private jets and superyachts. The investigation puts the listed property at $672 million.

The audited accounts that followed showed none of those assets. Amiscan reported about $75,000.

The mechanism, as the documents describe it, was a set of agreements dated to 2003 that moved the assets to Kelvedon Worldwide, a company in the British Virgin Islands. The files also include backdated trust agreements and share certificates. Deloitte signed off the replacement accounts as giving a “true and fair view”.

The timing matters. The documents link the effort to Cyprus’s new rules requiring companies to publish accounts, which took effect in the mid-2000s. Removing assets from Amiscan’s balance sheet meant they would not appear in public filings.

Who signed and who is named

The leak names MeritServus, a Limassol corporate services firm that spun out of Deloitte in 2005, as the entity that signed and backdated many of the documents. Its founder is Demetris Ioannides. His lawyers told the reporters he could not respond to requests for comment.

The correspondence also names Eugene Tenenbaum and Andre De Cort. According to the files, De Cort helped draft the documents and Tenenbaum approved the plan.

Other entities appear in the wider project. Kravin Investments received about $3 billion from a 2003 sale of shares in Sibneft, and the files allege that around $2 billion of it was removed from the balance sheet through backdating. Electus Investments, the Cypriot holding company at the top of the structure, is said to have been made to look as if it held about $145,000.

Antonis Taliotis, a senior tax adviser at Deloitte Cyprus until earlier this year, declined to comment through the firm.

Deloitte Cyprus response and the denials

Deloitte Cyprus said it “acts in compliance with applicable laws”. It told the reporters it could not comment on specifics because it no longer holds correspondence from more than 20 years ago. It also said each Deloitte firm is liable only for its own work and that it had seen no evidence of involvement beyond Cyprus.

Abramovich’s lawyers denied that their client knew of any unlawful backdating, tax evasion or misleading of Cypriot authorities. They said: “If an arrangement was proposed by professional advisers of Deloitte’s standing, it would have been entirely proper.”

Outside experts have been harsher. Andrew Mitchell KC, a financial crime barrister who reviewed the findings, said professionals in the structure “will stop literally at nothing in terms of creating documents”. Alex Cobham, chief executive of the Tax Justice Network, said Deloitte appears to have been “very much” part of the design process.

Those are assessments of leaked records. They are not findings by a court or regulator.

Deloitte Cyprus regulators and police respond

The Cyprus Public Auditing Oversight Board said it has been informed of the publications. Panos Prodromitis, its director general, said the board is “taking all necessary actions, within the framework of its legal responsibilities and obligations, with the aim of serving the public interest”. The board has not said what steps it is taking or what powers it will use.

Andreas Zachariadis, permanent secretary at the finance ministry, told a parliamentary committee the events occurred between 2003 and 2006. He said the oversight board had contacted the firm and received its explanation.

Police spokesman Andreas Anastasiades told the House institutions committee on October 21 that an investigation into how Abramovich’s assets were managed through Cypriot companies would run with other competent bodies and take about six months. A justice ministry spokesperson said information was being evaluated and a further inquiry would follow if indications of offences emerged.

The main allegation before the committee was that an audit firm encouraged a client to backdate documents to secure a tax benefit or alter how financial statements were presented.

The Institute of Certified Public Accountants of Cyprus has not issued a statement that we could find. Nor have sanctions authorities commented on the Deloitte Cyprus allegations. Abramovich was sanctioned by the UK and the EU in 2022 after Russia’s invasion of Ukraine, and the UK’s Office of Financial Sanctions Implementation enforces the British regime.

What Deloitte Cyprus means for audit and compliance teams

The case lands as audit firms face scrutiny of their work in several markets. In the UK, the Financial Reporting Council fined Deloitte more than £6 million over its Go-Ahead audits, and the profession’s regulators are weighing how firms evidence what they did and when. A separate review of BDO’s Manchester City audit showed how closely sports and ownership structures are examined.

Firms advising on offshore structures also face a changing anti-money laundering regime. Accountants and lawyers face FCA-led AML oversight from 2027, which puts the quality of client due diligence under a single supervisor.

The practical lessons are narrow. Document dates should be checked against system metadata, not accepted on the face of an agreement. Changes between draft and final accounts that remove large assets deserve a written explanation on the file. Related-party transfers dated years earlier need independent evidence that they occurred when stated.

None of this requires the allegations to be proved. It follows from what the leaked files say was done and from the fact that the accounts were public.

Deloitte Cyprus has not said whether it has opened an internal review. The police inquiry is expected to run for about six months from October 21, which points to April 2027.
