Russian opposition supporter jailed - UPI.com One of the opposition leaders Alexei Navalny speaks during a massive rally "Russia without Putin" in Moscow to protest against Vladimir Putin's victory in a presidential election on March 5, 2012. MOSCOW, March 16 (UPI) -- A court conviction for the husband of a prominent Russian opposition leader is a warning of what's to come under a Putin presidency, an advocate said. Russian court upheld a fraud conviction against entrepreneur Alexei Kozlov, the husband of journalist and opposition leader Olga Romanova. Koslov is accused of stealing shares from a leather production company in 2006. Lyudmila Milovidova, a freelance journalist and Romanova supporter, told The Moscow Times the conviction served as a warning to the opposition. "What happened today confirms once again that there is no fair trial in our country," she said. As long as the person who we have just elected (Putin) remains in power, lawlessness will continue. Left-leaning opposition leader Sergie Udaltsov, who had called for a million-man march to protest the results of a March presidential election, this week was sentenced to 10 days in prison following his arrest during anti-government demonstrations. Russian Prime Minister Vladimir Putin won a third non-consecutive term as president in an election this month. European observers said the election was skewed in his favor. Kozlov would serve two years in prison with credit for time served.
