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.

The hard-right nationalist who lost Romania’s presidential election rerun says he has asked a top court to annul the election results.

Romania’s pro-European Union, centrist presidential candidate Nicușor Dan won the country’s election Sunday, defeating his ultranationalist rival in a shocking upset.
