Peru's presidential runoff ended without a clear winner after an extremely close vote. A quick count by the pollster Ipsos, carried out with the NGO Transparencia on a representative sample of tally sheets, gave a slight edge to leftist candidate Roberto Sánchez, with 50.3% of the vote, against 49.7% for conservative Keiko Fujimori. The gap, within the margin of error, amounts to a technical tie that prolongs the uncertainty in a country that has had nine presidents in a decade.
