Former oil tycoon Mikhail Khodorkovsky has been found guilty in his second trial on charges of embezzlement, Russian news agencies say. A judge in Moscow said Khodorkovsky and his business partner had been found guilty of embezzling property. The verdict is still being read out. Khodorkovsky is already serving an eight-year sentence for fraud and tax evasion. His supporters maintain the case is politically motivated. Khodorkovsky, 47, was due to be released next year, but the second trial could see him jailed until 2017.
