Whatever the extent of Berezovsky's wealth, his expensive divorce, Patarkatsishvili's death and his paper mountain of litigation left it much reduced.
In 2008, Berezovsky was forced to sell the Darius, a 110-meter (360-foot) -long custom-built yacht that many believed was an attempt to compete with an even larger ship, the Eclipse, being built for Abramovich.
Earlier this month, the Times of London reported that Berezovsky was downsizing his art collection, selling off his homes, firing staff and closing his office in London's upscale Mayfair district.
In a January ruling in a dispute between Berezovsky and his ex-girlfriend, Helena Gorbunova, High Court Judge George Mann wrote that the oligarch's fortune appeared to have been spread thin.
“On the evidence, Mr. Berezovsky is a man under financial pressure,” he said.
