Romania's far right has four days to find a replacement presidential candidate for pro-Russian Calin Georgescu, who is unlikely to succeed on Tuesday in his attempt to overturn a ban on his standing in an election rerun in May.

Romania’s constitutional court upheld a decision banning presidential front-runner Calin Georgescu from May election, ending the bid that plunged the country into the biggest political crisis since the fall of communism.

The ban on Calin Georgescu running in Romania's May 4 presidential election has deepened existing political divisions, sparked protests, and raised concerns over Romania’s democratic future.
