Authorities have raided three of opposition leader Alexei Navalny’s offices in Moscow on the eve of a local election where he is advocating voters to unseat Kremlin-backed candidates.

The raids took place ahead of the Sept. 8 city legislature vote that galvanized this summer’s mass protests in Moscow when election officials disqualified opposition candidates, including some of Navalny’s allies, from the ballot. Navalny has promoted a “Smart Voting” strategy, urging supporters to vote for the candidates best positioned to beat Kremlin-aligned incumbents this Saturday.
