Russia's highest court has upheld election officials' decision to bar opposition leader Alexei Navalny from running for President in March's election. <br/><br/>The Supreme Court today turned down Navalny's appeal against the Central Election Commission's move, saying that the decision to bar him from the race fully conforms to law. <br/><br/>President Vladimir Putin, whose approval ratings top 80 per cent, is set to easily win a fourth term in the March 18 vote. <br/><br/>Navalny has campaigned for the presidency all year despite an implicit ban on his candidacy due to a fraud conviction seen by many as politically driven.<br/><br/>Election officials formally barred him from the ballot. Navalny responded to the ban by calling for a boycott of the vote. The Kremlin said authorities will look into whether such a call violates the law.
