Opposition leader Sergei Udaltsov attaches the protest leaflet to the Place of Skulls during a protest at the Red Square in Moscow, Sunday, April 8, 2012. Opposition activists called for supporters to walk around Red Square on Sunday wearing the white ribbons that have become a symbol of the protest movement against Prime Minister Vladimir Putin. Putin will begin serving a third presidential term in May. The leaflets at right depicts Vladimir Putin with a sarcastic condemnation of him saying "He is tired to lie, steal and promise".
