April 15 (UPI) — Leftist candidate Roberto Sánchez has moved into second place in Peru’s presidential vote count, positioning himself for the runoff election as officials continue to tally ballots from the general election.

With about 90% of ballots counted, official results from Peru’s National Office of Electoral Processes show Keiko Fujimori leading with 16.9% of the vote, securing her place in the runoff. The race for second place remains extremely close.

After three days of slow vote counting, Sánchez climbed to second place with 12,05% of the vote, edging far-right candidate Rafael López Aliaga, who has 11.94%.

Ballots in Peru are processed in the order they arrive, favoring candidates with stronger support in major cities during the early stages of the count. That has kept the country in suspense, as the remaining rural vote could solidify Sánchez’s lead, La República reported.

Sánchez, a congressman and head of the leftist Juntos por el Perú party, ran as the political heir to former President Pedro Castillo, under whom he served as trade minister. During the campaign, he adopted Castillo’s signature wide-brimmed hat in public appearances.

His platform calls for sweeping state reforms through a constituent assembly, Peru’s entry into the BRICS bloc and greater state control over strategic resources without expropriation, seeking support in the Andean south and rural regions.

If Sánchez advances to the June 7 runoff, the result would echo Peru’s 2021 presidential election, when Castillo, then a little-known union leader, unexpectedly reached the second round against Keiko Fujimori with 18.9% of the vote.

As Sánchez gained ground, López Aliaga called the election a “systematic fraud” and demanded the vote be annulled, alleging manipulation in the electoral authority’s data transmission system and logistical chaos, El Comercio reported.

Election observation missions Tuesday backed the integrity of the process, describing the vote as credible and transparent despite logistical problems that caused delays and forced some polling stations to remain open longer, according to France 24.

Peru’s comptroller general also warned of serious problems in the distribution of tally sheets and election materials during the 2026 vote, which reportedly delayed polling station openings in parts of the country, Latina TV reported.

Election authorities said the prolonged count is largely due to the technical complexity of processing ballots that combined five simultaneous elections: president, national senators, regional senators, lower house lawmakers and Andean Parliament representatives.

Voters were asked to choose among 35 presidential candidates and nearly 10,000 candidates for Congress and the Andean Parliament.

Facing criticism and legal complaints over the delay, the electoral office director, Piero Corvetto, defended the process and urged calm as officials continue counting ballots from Peru’s most remote rural areas.
