A top Romanian court has rejected an appeal by far-right politician Calin Georgescu to lift a ban on his candidacy in the presidential rerun.

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.

Călin Georgescu has sparked Romania’s deepest political crisis in decades, uniting Romanian nationalists, senior Trump administration officials and the Kremlin.
