LIMA, June 24 (Reuters) - Conservative Keiko Fujimori gained an insurmountable lead in Peru's presidential runoff late on Tuesday, setting her on track to assume the presidency.
Fujimori, a four-time presidential hopeful and the daughter of former President Alberto Fujimori, now has 50.11% of the votes, putting her ahead of leftist rival Roberto Sanchez by 43,386 votes. There remain only 40,213 potential votes to be counted, according to data from Peru's ONPE
electoral authority.
The electoral authority has yet to officially declare a winner and plans to do so in mid-July.
Fujimori's expected victory deepens Latin America's rightward shift, following outsider Abelardo De La Espriella's election in Colombia on Sunday. Voters concerned about crime have flocked to hardline candidates.
Earlier on Tuesday, Sanchez alleged that "fraud was underway", without providing evidence, and said he would refuse to recognize the results of the election, raising the prospect of a prolonged political crisis in Peru.
Sanchez had requested the annulment of thousands of votes cast abroad that mostly favored Fujimori, but Peru's national electoral jury rejected the request on Tuesday night.
The runoff results had been delayed by a review of contested ballots, the late arrival of ballots from abroad and the razor-thin difference between candidates.
Fujimori is set to inherit a country that has seen eight presidents in as many years and which is grappling with stark economic inequalities between the capital and rural regions as well as disillusionment with politicians.
Of the eight former presidents, none completed a full term. Three were impeached and one resigned after just six days. Four former presidents are currently in prison, and Fujimori's late father served 16 years over human rights abuses during his decade-long rule in the 1990s.
Fujimori, who previously distanced herself from her father's legacy, has leaned into it this election — casting herself as a strong leader best able to enforce order and stability as voters grapple with rising rates of extortion and murder.
