Imprisoned former oil tycoon Mikhail Khodorkovsky, once Russia’s richest man, has been sentenced to six more years in jail for fraud.
With his current sentence due to expire next year, Khodorkovsky, 47, now faces imprisonment until 2017.
He could “only be reformed by being isolated from society”, the judge’s verdict said.
Khodorkovsky was convicted on Monday in a judgment criticised by the US and others as selective justice.
Once seen as a threat to former President Vladimir Putin, he was found guilty along with former business partner Platon Lebedev of stealing billions of dollars from their own oil firm, Yukos, and laundering the proceeds.
