Neither the US nor the EU have so far imposed sanctions on Abramovich, so his Riviera interests remain untouched, at least for the moment.

Although it is impossible to know which trophy assets remain under his control behind a complex web of offshore holding companies, the star property in the oligarch’s portfolio must be the Château de la Croë, a palatial villa close to Antibes that was once home to the former king of England, Edward VIII.

The Duke of Windsor as he became known lived in the property for several years following the Second World War, before selling the property and moving full-time to Paris to live with his divorced American wife Wallis Simpson.

Abramovich’s yachts are no strangers to Mediterranean ports, but both the 140m Solaris and the 162m Eclipse are both safely at sea.

On the morning of the attack on Ukraine, February 24, a private jet registered to Abramovich left Nice Airport for Moscow. On the same day Putin called a meeting of his oligarch cronies at the Kremlin, although it is not known if Abramovich was present.

Forbes Russia reported last year that Abramovich had bought a Boeing 787-8 Dreamliner for 350 million. The aircraft flew from Moscow to Dubai and back again on March 4, FlightRadar24 reported.
