Khodorkovsky is richest man. And he lost everything when Putin arrested him and took his company away, and essentially took his company away, sold it, and gave it to other people, and enriched them. So, he's a complicated figure as an opposition leader, and people admire him - he was in prison, and he was very brave, and he's written some good things since then, and so on. But at the end of the day, people see him as being part of the corrupt system that has done so much to undermine the Russian system since the 1990s, and I don't know that he can ever be a really popular leader.
