Romania's defeated hard-right presidential contender George Simion said late on Tuesday that he would challenge the ballot's result, alleging interference by France and Moldova, after a centrist victory was met with relief by many European leaders.

Romania's Permanent Electoral Authority (AEP) confirmed on May 21 that the 2025 presidential elections were conducted in a climate of integrity, fairness, and transparency. It also rejected recent online accusations made by the losing candidate as "completely false and unfounded.

Nicusor Dan, the mayor of Bucharest, defeated George Simion, a nationalist aligned with President Trump who had been seen as the front-runner.
