MOSCOW: Russia?s Supreme Court on Saturday dismissed an appeal by Russian opposition leader Alexei Navalny against a decision by the country?s central election commission to bar him from taking part in next year?s presidential election.

The commission this week barred Navalny from taking part in the March 18 vote because of a suspended prison sentence he says was trumped up.

Navalny, who did not attend the Supreme Court hearing, wrote on Twitter that he and his supporters ?will not recognize elections without competition? and renewed calls for a boycott of the vote.

Polls indicate that President Vladimir Putin, who has dominated Russia?s political landscape for 18 years, is on course to be comfortably re-elected, but Navalny says his own exclusion from the vote makes a farce of the ballot.

Navalny, who has organized some of the biggest anti-government demonstrations in years, has been jailed three times this year and charged with breaking the law for organizing public meetings and rallies.
