Exiled Oslo Marine Group (OMG) owner Vitaly Arkhangelsky has lost a protracted legal battle against Bank St Petersburg (BSP) over defaults on personal loan guarantees worth $90m.

Nearly two years after the 46-day trial ended in the UK high court, Justice Robert Hildyard delivered a judgement allowing the lender to recover its money and dismissing "ultimate chancer" Arkhangelsky's $500m counterclaim that BSP illegally appropriated OMG's assets in 2009.
