Putin critic Alexei Navalny released during appeal of conviction MOSCOW - Russian opposition leader Alexei Navalny and his former business partner, Pyotr Ofitserov, were released from custody Friday, one day after their conviction in a controversial embezzlement case, Interfax news agency reported. A district court in the regional capital of Kirov had sentenced Navalny and Ofitserov to five years and four years in prison, respectively, and fined them $15,000 each on charges of embezzling $530,000 from a local timber company in 2009. The Kirov regional court ruled that both men should be released while they appeal the verdict. Upon his release, Navalny thanked his supporters "for making them release me." Thousands protested after the convictions. "Even if it is temporary, let's use this time to shake up the swindlers," Navalny wrote in his Twitter account. After the verdict and sentencing Thursday, massive protests broke out in a number of major Russian cities. The United States and other Western governments expressed concern with what they termed an example of biased, politically motivated justice. Under the pressure from protesters at home and concerned governments abroad, the Kremlin had to remedy the situation, said Andrei Piontkovsky, a senior researcher with the System Analysis Institute in Moscow. "By putting his key opponent in prison yesterday, Putin demonstrated that he is vengeful and not too smart as a politician," Piontkovsky said in an interview. Nikolay Svanidze, a popular television journalist and member of the Presidential Council on Civic Society and Human Rights, said the Russian judicial system is essentially an extension of the government and probably was following instructions from the Kremlin. "The fact that Navalny was ordered to be released the next day can only mean that the Kremlin was taken aback by the quick and uniformly negative reaction of the world political establishment and by a spontaneous and massive response from thousands of young people in Russia who joined protest actions in many cities and towns across the country," Svanidze said. He said Putin can't afford to be seen to be suppressing civic society on the eve of a visit by President Obama and with the Winter Olympics coming to Sochi in 2014. "There must be some real infighting between two different factions in the Kremlin over what line to pursue toward Navalny and the opposition in general," Svanidze said. Or else the Kremlin doesn't have a clue what to do next, and hence the embarrassing convulsions.
