Imprisoned former oil tycoon Mikhail Khodorkovsky, once Russia's richest man, has been sentenced to six more years in jail for fraud.
The former Kremlin insider is currently serving a term for tax evasion.
With his current eight-year sentence due to expire next year, Khodorkovsky now faces imprisonment until 2017, the BBC reports.
He was convicted on Monday in a judgment criticised by the United States and others as selective justice.
Once seen as a threat to the former president Vladimir Putin, he was found guilty along with a former business partner of stealing billions of dollars from their own oil firm, Yukos, and laundering the proceeds.
Lawyers for the two defendants are expected to appeal but if Khodorkovsky does remain in jail until 2017, it will mean he will not return to society until well after the next Russian presidential election.
