Exit polling in Poland is suggesting Andrzej Duda won the country's Presidential runoff.
Duda, representing right-wing Law and Justice Party, has received 53 percent of the vote.
Incumbent Bronislaw Komorowski has conceded defeat.
The loss marks a significant blow to the ruling Civic Platform party ahead of the parliamentary elections later this year.
The official results will be published by the National Election Commission on Monday evening.
