Alexei Navalny, the 'anti-Putin'

Tens of thousands of protesters took to the streets of Moscow, St. Petersburg and across Russia to demand the release of prominent Kremlin critic Alexei Navalny this past weekend. Police used force to break up the protests and detained more than 2,500 people. Navalny is best known for his anti-corruption investigations and was recently the subject of an assassination attempt. After recovering from his poisoning in Germany, Navalny returned to Russia only to be arrested and imprisoned in Moscow. CBC Russia correspondent Chris Brown talks to host Jayme Poisson about the growing movement in support of Navalny, and whether it might actually challenge President Vladimir Putin’s hold on power in Russia.
