In addition, by-elections and municipal elections will be held this weekend in a number of other regions, along with several referendums.
Two parties, Unified Russia and A Just Russia, are likely to dominate the polls. But opposition groups say both parties are fiercely loyal to the Kremlin, and complain that any real opponents have been sidelined.
Two-Horse Race
Critics say any real opposition has been pushed out of the vote to ensure that parliamentary elections later this year and the presidential election in 2008 go smoothly. An unusually high number of parties has been barred from running in the regional elections on technical grounds.
In St. Petersburg, the local election commission ruled that the opposition Yabloko party could not run in the city's Legislative Assembly elections after 10.5 percent of the signatures gathered for registration were declared invalid. Electoral law allows up to 10 percent of the signatures not to be valid. Yabloko is popular in St. Petersburg, usually receiving between 10 and 20 percent of the vote.
On March 6, Russia's Supreme Court rejected the party's appeal to be reinstated. A senior member of Yabloko in St. Petersburg, Mikhail Amosov, reportedly called the court ruling a "political decision."
St. Petersburg Boycott
Prior to the decision, Yabloko Deputy Chairman Sergei Mitrokhin, a State Duma deputy, said that the party was considering boycotting the vote in St. Petersburg.
"We will do this if the court decides against reinstating Yabloko in the polls. We consider that our candidature was removed unlawfully, under the instruction of the [St. Petersburg] governor, [Valentina] Matviyenko, who has a personal grudge against the opposition," Mitrokhin said.
