ASTRAKHAN, June 22 – RAPSI. Four lawsuits seeking to invalidate Astrakhan’s mayoral elections to be filed on Monday, Oleg Shein, an opposition mayoral candidate, told RIA Novosti on Friday.

“The legislation is subject to physical borders. A lawsuit is filed with the defendant’s address or the place where the action was committed. This is why one district court cannot consider a lawsuit which covers the city’s all four districts. We are preparing the relevant documents and on Monday will file applications to all four district courts of Astrakhan,” Shein said. 

United Russia party representative Mikhail Stolyarov won Astrakhan's mayoral elections on March 6 with 60 percent of the vote. A Just Russia's candidate Oleg Shein came second, with a little less than 30 percent.

Shein challenged the election results, saying that they were falsified, and went on a 40-day hunger strike with his supporters on March 16 to protest against the elections.

Vladimir Churov, Russia's chief electoral official, has later admitted there were "procedural irregularities" at 128 of Astrakhan's 202 polling stations.
