Linklaters is advising BP on a high-stakes dispute after Russian shareholders of the UK company’s local joint venture (JV) TNK-BP launched a claim to halt BP’s planned alliance with Russian oil giant Rosneft.

Linklaters London head of litigation Michael Bennett was instructed to advise BP, after the billionaire shareholders who make up the Alfa-Access-Renova (AAR) consortium that owns 50% of TNK-BP filed for an injunction in the High Court earlier this week to block the planned Rosneft partnership.
