May 22 (UPI) -- Far-right Romanian presidential candidate George Simion lost a legal bid Thursday to annul last weekend's run-off election after a surprise loss to centrist rival, former Bucharest Mayor Nicusor Dan.

Romania's Constitutional Court threw out the challenge to the election result by Simion, who accused foreign states, including France, of vote-buying and alleging ballot fraud involving some of Nicusor's votes.

In a unanimous decision, the judges ruled Simion's request to annul the election was "unfounded" because the presidential poll complied with all "procedures within the scope of its authority," the court said.

Simion, leader of the Alliance for the Unity of Romanians party, attacked the decision, calling it a "coup" and urged his supporters to fight on.
