The High Court of London will start hearing a £2 billion lawsuit on Monday filed by Boris Berezovsky, a Russian billionaire currently living in the UK, against his former business partner Roman Abromovich. Berezovsky is seeking compensation for a number assets he was forced to sell to Abramovich between 2000 to 2003. Berezovsky claims in his lawsuit that Abramovich intimidated him and his business partner Badri Patarkatsishvili into selling a number of assets including a 43 percent in Russian oil company Sibneft, and a stake in the aluminum group Rusal, for significantly less than the shares were worth. The British mass media has described the dispute between two Russian oligarchs as the legal battle of the year.
