Right-wing Fujimori holds narrow lead one week before Peru presidential runoff, polls show

LIMA, May 31 (Reuters) - Right-wing candidate Keiko Fujimori holds a narrow lead over leftist Roberto Sanchez one week ‌before Peru's presidential runoff, two polls showed on Sunday.

Fujimori is ‌expected to take 38% of the votes while Sanchez is predicted to secure 35% in ​the runoff on June 7, according to the Ipsos poll conducted May 29-30 and published in the local newspaper Peru 21.

Support for Fujimori fell by one percentage point compared to the previous Ipsos poll, while Sanchez ‌maintained the same level of ⁠support. The number of people who said they would not vote for any candidate or would spoil their ⁠ballot increased by one percentage point to 27%.

"The big question in the final week is what undecided voters or those who say they plan to ​cast ​a blank or invalid ballot will ​do," said Alfredo Torres, CEO ‌of Ipsos. "The logic of choosing the lesser evil will ultimately determine who will be president of Peru for the 2026-2031 term."

Another poll, conducted May 26-30 by Datum Internacional and published in the local newspaper El Comercio, showed Fujimori securing 39.8% of the vote and Sanchez taking 35.9%.

Fujimori, ‌late former President Alberto Fujimori's daughter who ​is running for the fourth time, won ​the first round on April ​12 with 17% of votes. Sanchez, an ally of ‌jailed former leftist President Pedro ​Castillo, narrowly secured a ​place in the runoff with 12% of votes.

Ipsos' poll had a ​margin of error of ‌2.8 percentage points while Datum Internacional had a margin of ​error of 2.5 percentage points.
