Romania's electoral body has rejected the candidacy of controversial far-right politician Diana Sosoaca in the presidential election rerun in May, but approved George Simion, the leader of the country's most popular far-right party.

Controversial Romanian politician Diana Sosoaca, who was barred by a top court from entering last year’s annulled presidential election, filed her candidacy on Thursday in an unlikely bid to enter the May rerun.

Former Romanian Prime Minister Victor Ponta joined the race for May's presidential election re-run on Wednesday as the hard right worked to ensure they had a candidate in the contest after the ban on pro-Russian Calin Georgescu threw the vote wide open.

Romania's populist far-right politician George Simion is making his bid for the country's presidential election rerun in May as he seeks to rally nationalist voters after a controversial frontrunner was barred from the race last year.

The 62-year-old Georgescu will lodge his appeal to Romania’s Constitutional Court in the capital Bucharest, a day after the Central Election Bureau rejected his candidacy, accordingly to close political ally George Simion. The court will have 48 hours to make a decision.

Romania’s central election authority barred far-right candidate Calin Georgescu from competing in May’s presidential election re-run, not the European Union, contrary to misleading posts online.
