His supporters gathered in 20 cities across the country to secure the signatures.
"It's you, Vladimir Putin, who turned this country into a source of personal enrichment for yourself, your family and your friends. It's why you shouldn't be president anymore, it's why you're a bad president", Al Jazeera quoted, Navalny as telling the gathered crowd.
According to Navalny's campaign, over 15,000 people endorsed him nationwide and over 700 people supported Navalny's candidacy in Moscow.
