Mikhail Khodorkovsky, the jailed Russian oligarch, voiced doubts on Wednesday that Dmitry Medvedev, Russia’s likely next president, would be able to undo damage to the rule of law inflicted during the Putin era.

In his first face-to-face interview since his arrest in 2003 on fraud charges, Russia’s one-time richest man spoke to the Financial Times about his incarceration, his concerns for his own future and his long-term optimism for Russia.
