May 15 (UPI) -- Peru's National Office of Electoral Processes finalized the official vote count Friday after 33 days of scrutiny and legal challenges, confirming that right-wing candidate Keiko Fujimori and leftist candidate Roberto Sánchez will compete in a presidential runoff June 7.

The final tally of the mid-April voting placed Fujimori first with 17.18% of valid votes.

The main battle centered on second place, where Sánchez secured 12.03% and narrowly overtook conservative candidate Rafael López Aliaga, who finished third with 11.90%, trailing by just 21,210 votes.

"The race for the runoff produced a scenario similar to 2021, with a contest between the left and the right," electoral law expert José Tello told RPP Noticias.
