Peru's electoral court certified Keiko Fujimori as president on July 3, 2026, ending three and a half weeks of vote counting and disputes over the June 7 runoff result. She won with 50.135% of the vote against Roberto Sánchez's 49.865% — fewer than 50,000 ballots separated them across the entire country, according to BBC News.

This is Fujimori's fourth attempt at the presidency. She ran and lost in 2011, 2016, and 2021; her 2021 loss to Pedro Castillo came by a similarly tight margin and sparked months of post-election challenges before a final outcome was settled. Peru has developed a pattern: runoffs in this country routinely trigger drawn-out disputes. This cycle is no longer an exception — it has become standard.

The Jurado Nacional de Elecciones (JNE) — Peru's highest electoral authority — issued the formal proclamation required by law to make a result official and binding. Fujimori held a press conference immediately afterward, CNN reports. She will be inaugurated on July 28, Peru's independence day and the customary date for swearing in a new president. With her arrival, Peru will have had nine presidents in roughly a decade — a pace that reflects the deep institutional instability the country has endured since 2016, marked by impeachments, resignations, a presidential death while imprisoned, and one leader's attempt to seize absolute power.

Within hours of the proclamation, Sánchez's party filed an appeal with the JNE demanding that the entire runoff be annulled because the vote was "seriously compromised." The party has not yet publicly detailed whether it is alleging procedural violations, fraud, or both. Peruvian electoral law sets a high bar for overturning a certified result — and the JNE itself verified this outcome. Any reversal would break with precedent. An annulment is unlikely to delay Fujimori's July 28 inauguration unless the tribunal acts with unusual haste, but the pending appeal will cast a shadow over her opening weeks in office as a question of legitimacy her opponents will press.

Keiko Fujimori is the daughter of Alberto Fujimori, who ruled Peru from 1990 to 2000 and was later convicted of crimes against humanity for extrajudicial killings and forced sterilizations that occurred under his administration. He died in September 2024. Throughout her political career, Keiko has tried to reshape that legacy — conceding that there were "excesses" while arguing that her father's economic reforms and counterinsurgency efforts were legitimate achievements. For a substantial portion of voters, the association remains a problem. The narrow margin of her victory is testament to that divide.

Her party, Fuerza Popular, occupies Peru's political right, advocating for stronger security measures, private investment, and a pullback from the regulatory policies introduced by recent left-leaning administrations. The Trump administration publicly welcomed her win, Fox News reported, consistent with its stated preference for right-leaning governments across the Americas.

The regional dimension of this outcome warrants attention. Colombia's Abelardo de la Espriella won his presidential race in roughly the same timeframe, BBC News notes, adding a second rightward swing across South America in a matter of weeks. The electoral cycle in the region has shifted, at least for the moment, away from the center-left governments that dominated the early 2020s.

For Peru itself, the near-term challenge is administrative as much as political. Fujimori will take office with a Congress split across multiple parties, none holding a majority — the same fractured legislative landscape that undermined her predecessors. Since Martín Vizcarra left office, no Peruvian president has managed to assemble a stable coalition strong enough to pass a budget or push through major reforms. Whether Fujimori's narrow and contested victory can generate the political capacity to break that pattern — or whether it will constrain her from the start — will become clear in her opening months.
