Roman Abramovich, the Russian oligarch and owner of Chelsea football club, has won his court battle against Boris Berezovskyin the most expensive litigation case in British legal history.

66 year old fellow Russian Berezovsky was seeking around £3.8bn from Abramovich after claiming he'd been betrayed and intimidated into selling shares in oil giant Sibneft.

The London commercial court judge, Mrs Justice Gloster, ruled against Berezovsky, claiming he was an "unimpressive and inherently unreliable" witness.

Berezovksy said afterwards he was shocked by the decision, and that he did not know whether he was going to appeal. It's reported he spent £100m fighting the case, which has involved an army of lawyers.

The three month long trial detailed the former friendship of the two billionaires, before things turned sour and Mr Berezovsky fled from Russia to France in 2000 after falling out with President Vladimir Putin. Berezovsky said Abramovich was a "gangster", who in return described Berezovksy as a "megalomaniac".

Mr Abaramovich was not in court for the hearing, and is believed to be in Monte Carlo ahead of Chelsea's Super Cup Final clash with Atletico Madrid tonight.
