Mikhail Khodorkovsky (Author) In the early 2000s, Mikhail Khodorkovsky was one of the wealthiest men in Russia, the head of the giant Yukos oil company, ranked 16th on Forbes list of world billionaires. But his pro-democracy, anti-corruption views led to a clash with President Vladimir Putin, who had him arrested in 2003. Convicted on politically motivated fraud charges, Khodorkovsky spent ten years in Putin's prison camps, recognised by Amnesty International as a prisoner of conscience. Since his release in December 2013, Mikhail Khodorkovsky has lived in exile in Switzerland and in the UK. He is the founder of the Open Russia movement, promoting political reform in Russia, including free and fair elections, the protection of journalists and activists, the rule of law and media independence. He has been described by The Economist as 'the Kremlin's leading critic-in-exile.' Martin Sixsmith (Author) Martin Sixsmith studied Russian at Oxford, Leningrad and the Sorbonne. He was a Slavics Tutor at Harvard and wrote his postgraduate thesis about Russian poetry. From 1980 to 1997 he was the BBC's correspondent in Moscow, Washington, Brussels and Warsaw.
