Keiko Fujimori's razor-thin victory in Peru returns polarising dynasty to power as rival cries fraud

A razor-thin margin after a tense count

With 99.87% of the ballots counted, right-wing candidate Keiko Fujimori has secured an unbeatable lead in Peru's presidential runoff. She holds 50.11% of valid votes against 49.88% for leftist congressman Roberto Sanchez, a gap of 43,386 votes. The electoral authority (ONPE) has yet to formally declare the winner, but the remaining uncounted ballots cannot overturn the result. Fujimori called her victory "irreversible."

The victory seems irreversible.

The expat vote becomes the flashpoint

Sanchez and his party Juntos por el Perú have refused to concede, alleging fraud centred on overseas ballots. Expat voters favoured Fujimori by over 63%, handing her a decisive advantage. If the foreign votes were excluded, Sanchez would lead with 50.11%. Sanchez claims the foreign ministry, led by chancellor Carlos Pareja, improperly exempted consulates from digitally submitting results and allowed physical ballot boxes to be shipped to Lima without adequate safeguards.

This grave irregularity amounts to an ongoing fraud. Under these conditions of rule-breaking, we will not recognise Ms Fujimori's government.

The electoral jury (JNE) dismissed a challenge to annul the expat vote, ruling it was filed late and without a required fee.

Analysts dismiss fraud claims as irresponsible

Political analysts and international observers have uniformly rejected the fraud allegations. Both the national and international missions reported no irregularities during the two rounds of voting. Eduardo Dargent, a political scientist at the Pontifical Catholic University of Peru, called the strategy a poor-loser tactic that risks further instability.

The path of fraud accusations has no future. These are unfounded claims that make them look like very sore losers.

Annette Schwarzbauer of the Konrad Adenauer Foundation noted that even political forces that backed Sanchez are distancing themselves from his refusal to recognise a Fujimori government.

The fraud narrative is losing force because neither international nor domestic observers reported any incidents.

A dynasty returns after a decade of turmoil

Fujimori's triumph in her fourth presidential bid resurrects the polarising "Fujimorismo" movement built around her late father, Alberto Fujimori. The former president governed from 1990 to 2000, stabilising the economy but later serving 16 years in prison for human rights abuses. Keiko Fujimori once distanced herself from that legacy but campaigned as a strong hand to tackle surging crime, extortion, and corruption. She has proposed reviving "faceless judges," a system condemned by rights groups in the 1990s.

What comes next

Fujimori is due to assume office on 28 July for a five-year term, taking the helm of a copper-exporting nation where no president has completed a full term in the past decade. Juntos por el Perú has called for a day of "democratic resistance" on 27 June, and Sanchez urged street mobilisations. The official proclamation of the winner is expected in mid-July, after all challenges have been resolved.
