Addleshaws team exit fails to deter Berezovsky

Addleshaw Goddard has retained Boris Berezovsky as a client despite the exit of litigation head Simon Twigden, who led the team acting for the Russian oligarch.

The firm landed the client in October 2008 after he parted company with Cadwalader Wickersham & Taft.

Twigden was key to winning the account, but after he resigned earlier this year (The Lawyer, 23 April) questions were raised about whether the firm would retain the relationship.

The self-exiled oligarch has mounted a $5bn (£3bn) claim against Chelsea Football Club owner Roman Abramovich, providing a lucrative revenue stream for the firm.

Earlier this year Abram­ovich’s legal team, led by Brick Court Chambers’ Andrew Popplewell QC, went to the High Court in a bid to have the claim thrown out. According to sources close to Addleshaws that strike-out hearing earned the firm approximately £8m in legal fees.

A 10-week trial has now been scheduled for the High Court in October next year and, according to one source, fees are expected to escalate significantly.

The firm is also acting for the oligarch in a multibillion-dollar claim against Inna Gudavadze, the widow of his former business partner Georgian oligarch Arkady “Badri” Patarkatsishvili.

Twigden quit the firm in April, announcing plans to launch his own boutique along with high-flying partner Pietro Marino. Last month, Addleshaws partner Michael Green announced his intention to join the boutique.

They will leave the firm at the end of this month, along with eight fee-earners.

The firm declined to comment on the case.
