The Soviet-born Abramovich took advantage of Russia’s privatization laws in the early 1990s to gain considerable financial and political influence there. His friendship with Russia’s first post-Soviet President, Boris Yeltsin, was instrumental in his business career, and eventually placed him in close proximity to Russia’s current President, Vladimir Putin. Unlike many other oligarchs, Abramovich is believed to have remained close to Putin, despite living mostly in the United Kingdom in the past decade. The Russian oligarch has been staying in a mansion valued at close to $120 million in London’s exclusive suburb of Kensington. His lawyers have been renewing his British residence visa every six months.

However, the attempted assassination of Russian former spy Sergei Skripal earlier this year prompted the British government to intensify its scrutiny of Britain’s sizeable Russian expatriate community. London introduced tighter regulations that require Russian citizens applying to live in the UK to declare the source of their income in a far greater detail than previously. Soon after the new regulations were put in place, Abramovich’s lawyers withdrew his application to renew his British residency visa. Then, in May of this year, the Russian oligarch acquired Israeli citizenship. He has made it clear, however, that he does not intend to live in Israel. Instead, his legal team focused on an application for Swiss residency, which Abramovich first filed in the summer of 2016. In the application papers, Abramovich wrote that he intended to reside full time in Verbier, an Alpine village in the canton of Valais that is a popular holiday destination for celebrities and royalty.

A year later, following resistance and increasingly persistent questioning from the Swiss government, Abramovich’s legal team withdrew his residency application. Last February, when the Swiss press attempted to investigate the reasons behind the Swiss government’s reluctance, Abramovich’s lawyers secured an injunction forbidding the publication of information regarding his application to live in Switzerland. But the injunction was overturned late last week, and on Tuesday the Swiss media conglomerate Tamedia published some of the relevant documents. They include a letter from the Swiss Federal Police that strongly cautions against allowing the Russian-Israeli oligarch to resettle in Switzerland. The letter remarks that Abramovich has been repeatedly implicated in “suspicion of money laundering” and that the billionaire is “presumed [to have] contacts with criminal organizations”. Additionally, the letter states that Abramovich’s “assets are at least in part of illegal origin”. The letter concludes by strongly cautioning against allowing the oligarch to move to Switzerland, and argues that doing so would pose a “threat to public security” and be detrimental to the country’s international reputation.

The letter has raised eyebrows since its publication, because Switzerland is known for being highly welcoming of foreign billionaires while displaying minimal curiosity about the sources of their fortunes. Moreover, there are no known court rulings against Abramovich for money laundering or connections to organized crime. It is therefore presumed that the Swiss police report is based mostly on confidential informants and other informal sources. On Wednesday, Abramovich’s Swiss lawyer, Daniel Glasl, issued a statement saying that the Russian-Israeli magnate has never been charged with involvement in money laundering. He also reminded readers that his client has a blank criminal record.
