The origin of these revelations points to a network involving Eugene Shvidler—a billionaire businessman and ex-director of Chelsea FC—who played a pivotal role in sanctioning strategic investment decisions. Shvidler reportedly moved his operations to the USA following Russia's invasion of Ukraine but lived in the UK for many years, acquiring British citizenship in 2010.

Tax experts affirm that if it is proven that Shvidler was making significant investment decisions while based in the UK, it could be considered strong evidence that significant amounts should have been taxed as UK earnings. Both Shvidler’s and Abramovich’s legal teams maintain that they acted in compliance with tax laws and refute any wrongdoing.

Further investigation reveals that a substantial portion of Abramovich's untaxed wealth was funneled back into Chelsea FC, allowing for hundreds of millions of dollars to be linked directly to investments that artificially minimized tax liability.

Calculations by tax analysts project a potential tax bill exceeding £500 million, which could increase to over £1 billion when accounting for late payments and penalties. The situation has raised alarms, prompting calls from politicians for the HM Revenue and Customs (HMRC) to launch an investigation to recover funds that could contribute to the UK’s public budgets.

As ongoing sanctions against Abramovich complicate the financial landscape, an additional $2.5 billion from the sale of Chelsea FC remains frozen due to disputes over its intended use, further complicating the financial implications of Abramovich's business dealings. The revelations come amidst a broader investigative effort—dubbed Cyprus Confidential—uncovering links between Russian oligarchs and strategic financial practices designed to evade taxes.
