Romanian far-right presidential contender Calin Georgescu said on Monday he would challenge a decision to bar him from taking part in an election rerun in May, but analysts said his chances of standing were slim amid fears of Russian meddling.

Romania’s electoral body on Sunday rejected Calin Georgescu’s candidacy in a presidential election redo, after the far-right populist won the first round of last year’s race before a top court annulled the election.

Georgescu submitted his presidential bid on Friday after allegations of Russian interference in his favor prompted Romania's Constitutional Court to cancel the original election in December
