Jailed Russian tycoon Mikhail Khodorkovsky has been moved to Moscow for a new trial his defence fears could keep him behind bars for two more decades.Once Russia’s richest man, Khodorkovsky has been held in Siberia, where he is serving an eight year sentence for tax evasion and other offences. Now facing fresh charges of fraud and theft, he and ex business partner Platon Lebedev are, according to Russian media, accused of embezzling nearly a trillion roubles, that is more than 20 billion euros. Both have been transferred to a jail in the capital ahead of their trial, which is due to start early next month. Supporters of Khodorkovsky, who was arrested in 2003, say he was unfairly targeted because of his political ambitions and criticism of then president Vladimir Putin’s administration. The former head of oil giant Yukos, Khodorkovsky has always proclaimed his innocence, saying he was the victim of corrupt officials under Putin, who wanted to carve up his business empire.
