An opposition activist holds a cut-out from the cover of a magazine displaying Russian blogger, political and social activist Alexei Navalny during a rally to protest against violations at the parliamentary elections, in Russia's far eastern city of Vladivostok December 10, 2011. Prime Minister Vladimir Putin's opponents hope to bring large numbers of people out onto the streets across Russia on Saturday for rallies that will test their ability to channel outrage over allegations of election fraud into a powerful protest movement.
