Skadden Arps Slate Meagher & Flom has won an arbitration victory for the Alfa-Access-Renova (AAR) group in its dispute with BP over its proposed $16bn (£10bn) strategic alliance with Russia’s Rosneft.

The arbitration tribunal ruled last week (24 March) that BP will not be allowed to enter into an alliance with Russian state-owned oil company Rosneft, which would have involved an equity-linked partnership to pursue joint projects in the Russian Arctic shelf.
