Russian tycoon Oleg Deripaska has lost his appeal to block a $4bn (£2.4bn) dispute over his stake in aluminium giant RUSAL from being heard in the UK.

Following a ruling handed down last week (31 July) by the Court of Appeal, the long-running dispute between RUSAL owner Deripaska and Israel-based businessman Michael Cherney over a 20% stake of aluminum giant RUSAL is set to remain in UK courts.
