MOSCOW — Associates of Aleksei A. Navalny have been forced to disband the imprisoned Russian opposition leader’s network of 40 regional offices, one of his top aides said Thursday, a step that pushes the domestic resistance to President Vladimir V. Putin further underground.
The move was inevitable, Mr. Navalny’s aide, Leonid Volkov, said in a YouTube video, amid the Kremlin’s latest efforts to stifle political dissent. Moscow prosecutors on April 16 announced that they would seek a court ruling to have Mr. Navalny’s movement declared an extremist organization, and the court quickly ordered Mr. Navalny’s groups to halt all public activity, including participating in political campaigns or referendums.
“Alas, we must be honest: it’s impossible to work under these conditions,” Mr. Volkov said, warning that continuing to operate would expose Navalny supporters to criminal prosecution. “We are officially disbanding the network of Navalny offices.”
Mr. Volkov predicted that while some offices would close, others would transform into independent political entities engaged in local politics. Either way, the end of Mr. Navalny’s nationwide network — from Kaliningrad on the Baltic Sea to Vladivostok on the Pacific — represented the end of an era in Russian politics.
February conviction for defamation of a World War II veteran that resulted in an $11,500 fine. The court denied the appeal.
It was Mr. Navalny’s first public appearance since he started his hunger strike demanding better medical treatment.
Mr. Navalny ended the hunger strike last week after 24 days, saying his demands had been partially met. On the courtroom video screens, Mr. Navalny appeared gaunt, but as he talked over the judge’s attempts to interrupt his closing statement, his voice sounded nearly as forceful as it was in his dramatic courtroom appearances earlier this year.
Mr. Putin, Mr. Navalny said, was trying to wrap himself in the glory of the Soviet Union’s victory in World War II in order to justify his effort to stay in power.
“Your king with no clothes has stolen the banner of victory and is trying to fashion it into a thong for himself,” Mr. Navalny said, addressing the judge, according to a recording of his speech published by the BBC’s Russian-language service. “All your authorities are occupiers and traitors.”
splashy corruption investigations published on YouTube, the local offices highlighted what they described as theft and injustice carried out by local officials.
“Most will continue their work as self-sufficient, independent, regional civic and political movements, with strong people at the helm,” Mr. Volkov said of the offices. “This means that everything we have done together up until now will not have been for naught.”
