BP fights to salvage Rosneft deal
A court in London will decide whether oil giant BP can salvage any part of its deal with Russian company Rosneft.
The arbitration tribunal will determine whether BP's share-swap with the Russian oil company can still go ahead.
The deal is opposed by the oligarchs in BP's Russian joint venture TNK-BP. The tribunal has already ruled against the share -swap, the tie-up deal and BP's Arctic exploration with Rosneft.
But BP is challenging the ruling on the share swap.
Mikhail Krutikhin, an analyst at RusEnergy told the BBC why the deal is important to BP.
