Russian opposition figure Mikhail Khodorkovsky, the former owner of the Yukos Oil Co., poses for a photo after being interviewed by The Associated Press in London, Tuesday, July 24, 2018. After President Vladimir Putin came to power in 2000, he was reported to have told about two dozen of the men regarded as Russia's top oligarchs that if they stayed out of politics, their wealth wouldn't be touched. Khodorkovsky, regarded as Russia's richest man at the time, established the Open Society reformist group and showing increased political ambitions. But he was arrested in 2003 and spent a decade in prison on convictions of tax evasion and embezzlement before Putin pardoned him and he left Russia. (AP Photo/Matt Dunham, File)
