Romania's ruling leftist Social Democrats (PSD) looked set to win the most votes in a parliamentary election on Sunday, fending off a resurgent far-right movement that challenges the country's pro-Western orientation,

Romanian centrist and leftist parties looked to have fended off a surge by the nationalist right in Sunday's parliamentary election, as attention turned to a top court ruling later on Monday on whether to annul the results of a presidential vote.

Romania's Constitutional Court on Monday validated the shock first-round result in its presidential election, setting the stage for a run-off vote on Dec. 8 that could upend the country's pro-Western orientation and erode backing for Ukraine.

Romania's ruling center-left Social Democrats were poised to secure the most votes in Sunday's parliamentary election, according to preliminary results published Monday.
