Fujimori leads chaotic Peru vote, election officials face charges
With more than half the votes counted, Fujimori -- the daughter of disgraced former president Alberto Fujimori -- led with about 17 percent of the vote, according to electoral authorities.
The battle for second and a place in a June runoff was on a knife-edge, with millions of votes still to be tallied and the count advancing painfully slowly.
The full results may not be known for days.
Rafael Lopez Aliaga, a wealthy former Lima mayor who has vowed to "hunt" down migrants, was on 14 percent of the vote.
