MOSCOW, September 12 (RAPSI) - Alexei Navalny, an opposition activist and the runner-up in the mayoral election, is filing numerous lawsuits with The Moscow City Court contesting the election results, RAPSI reports from the courtroom Thursday.

One large lawsuit is being filed with the Moscow City Court along with 951 more to be filed in various jurisdictions throughout Moscow. The lawsuits are based on Navalny's theories of uneven media coverage for the candidates, as well as attempts to sway the vote of Moscow's senior citizens by unlawful means.

Navalny received 27.24%of the vote on Sunday, compared with the 51.37%received by acting Mayor Sergei Sobyanin, a former Kremlin official, according to the city's election commission. Communist Party nominee Ivan Melnikov received 10.69%, and the three remaining candidates all scored in the single digits.

Independent election monitor GOLOS, which deployed a network of election observers on Sunday, placed Sobyanin's result at 49.45%and Navalny's at 28.56%.

Navalny claimed on his blog Monday that at least 28,000 ballots, or 2%of the vote, were rigged to give Sobyanin more than 50%, thus ruling out a runoff.
