Yet Alexei Navalny and his supporters continue to work on ways to remain a thorn in President Vladimir Putin's side, even as one of his most important financial backers says the movement in its current form is finished and will take time to rebound.
In the eyes of the Kremlin, the only half-meaningful political weapon the Navalny camp has left is its campaign for tactical, or what it calls "smart" voting against the ruling United Russia party in a parliamentary election in September, according to three people close to the Russian authorities.
Navalny's supporters are set to be barred from that election via a court case, due to unfold later this month, and planned legislation unveiled on the parliamentary website on Tuesday that would ban "extremists" from running for office.
A court, meeting in secret, is considering a request from Moscow prosecutors to have Navalny's network designated "extremist" for allegedly plotting a revolution, state media have reported. Russia's financial monitoring agency has already added the network to a list on its website of groups involved in "terrorism and extremism".
