Over the past decade, the anti-corruption activist Alexey Navalny has become one of the most influential opponents to President Vladimir Putin. Last August, he was poisoned by Putin’s secret police, and he spent five months recovering in Berlin. Last week, on his return to Moscow, he was detained by Russian authorities. Since then, tens of thousands have taken to the streets to protest his arrest. Masha Gessen joins Dorothy Wickenden to discuss how Navalny repeatedly outwits the Kremlin, and what these protests could mean for him, and for Putin’s regime.
