Partial results show that Romania's center-left prime minister will face a city mayor in the runoff of a presidential election after no candidate secured a majority of the vote.

With 56 percent of the votes counted early Monday, Prime Minister Victor Ponta had won 39.6 percent of the vote while the mayor of Sibiu, Klaus Iohannis, had 30.2 percent.

Romanians were voting to elect a new leader as President Traian Basescu steps down after 10 years.

Ponta, 42, says if he wins there will be stability and an end to bitter feuding between the prime minister and president.

Iohannis, 55, who is center-right, says he will guarantee an independent justice system and the rule of law.

Final results are expected later Monday. The runoff will be on Nov. 16.
