Sarah Montague speaks to Vladimir Kara-Murza, Vice-Chairman of the pro-democracy movement Open Russia. He was rushed to hospital in Moscow when his organs started failing and says he knew immediately what was happening because the same thing had happened two years previously. Both times he claims, he was the victim of deliberate poisoning. He also claims he was targeted because of his opposition to President Putin and the Russian government. After his stay in Washington, where he is currently recovering, he intends to go back to Moscow. Does he still fear for his life?(Photo: Vladimir Kara-Murza)
