On 7 December 2015 RFE/RL reported that Mikhail Khodorkovsky, former owner of the Yukos oil company who spent 10 years in jail in Russia on charges of fraud and embezzlement widely believed to have been politically motivated, said he had been formally charged in a criminal case involving the 1998 killing of a Siberian mayor. Khodorkovsky said the federal Investigative Committee had summoned him to appear for questioning on 11 December, but that he would not attend. Khodorkovsky said the summons did not set out the nature of the accusations against him. RAPSI subsequently reported that Khodorkovsky has been charged in absentia with organizing the 1998 murder of Nefteyugansk mayor Vladimir Petukhov, and with the attempted assassination of Petukhov’s bodyguard Vyacheslav Kokoshin and manager of East Petroleum HandelsGes mbh oil company Evgeny Rybin. The Investigative Committee said Khodorkovsky would be put on a wanted list if he did not appear for questioning. Former Yukos shareholder Leonid Nevzlin, who moved to Israel in 2003, was sentenced in 2009 in absentia to life in prison for the murder of Petukhov. Aleksei Pichugin, former chief of economic security at Yukos, was found guilty of murdering Petukhov and received a life sentence in 2008. Aleksei Pichugin is currently in prison in Russia. On 9 December, RFE/RL has reported, Mikhail Khodorkovsky, speaking in London where he now lives, said that a new revolution was 'inevitable and necessary' in Russia. In his speech Khodorkovsky predicted that President Vladimir Putin's government would be out of power in a few years' time.
