A joint investigation involving BBC Panorama, the Bureau of Investigative Journalism and OCCR says advisers linked to Roman Abramovich used backdated paperwork to alter records of his offshore assets held through companies in Cyprus. The reports describe how documents allegedly removed billions in assets from company accounts, including references to assets such as yachts and properties that later appear to have “disappeared” from records.

The investigation is based on analysis of thousands of leaked emails and corporate materials. The outlets broadly frame the conduct as part of an effort to disguise asset ownership and reduce tax exposure, pointing to backdating practices that would allow changes to be reflected in financial documentation after the fact. While the reporting relies on leaked and analysed records rather than court findings, it raises questions about the role of professional services firms, naming Deloitte Cyprus among those implicated. Commentary on other platforms discusses similar allegations of document falsification to evade tax, aligning with the core claims in the main coverage.
