A court declared oil tycoon Mikhail Khodorkovsky guilty of an array of charges Tuesday including fraud and tax evasion, and sentenced him to nine years in prison minus time served. The declaration of guilt and sentence came in the 12th day of the laborious verdict-reading process in the most closely watched trial of post-Soviet Russia, and one that has been widely criticized as politically motivated, AP reported. Khodorkovsky, the former head of the Yukos oil company and once estimated to be Russia's richest man, has already spent 583 days in jail, meaning he would serve about another seven and a half years in prison. Khodorkovsky looked straight ahead as the sentence was pronounced. His co-defendant Platon Lebedev, found guilty of the same charges and was given the same sentence.
