Former Russian dissident leader Alexei Navalny‘s supporters showed up at polling stations at noon, his final coordinated act of protest.

Shortly before his death, Navalny endorsed a protest called “Noon Against Putin,” where supporters would simultaneously show up at polling stations at noon to subtly express their opposition to the Kremlin. The demonstration occurred on the last day of voting in the Russian presidential election, considered by many to be a rubber stamp procedure to extend Russian President Vladimir Putin‘s rule.
