Peru Heads to Runoff With Fujimori Leading and Sánchez Facing Charges
Key Facts
—The runoff: Peru’s electoral authority ONPE confirmed on May 13 with 99.94% of ballots counted that right-wing Fuerza Popular leader Keiko Fujimori (17.18%, about 2.876 million votes) will face left-wing Juntos por el Perú candidate Roberto Sánchez (12.02%, about 2.012 million votes) in the June 7 runoff, with Sánchez narrowly defeating ultra-right Rafael López Aliaga (11.91%, about 1.994 million) by roughly 18,800 votes for the second-round slot.
—The prosecutor request: Peru’s Public Ministry requested on May 12 a sentence of five years and four months of prison for Sánchez plus permanent disqualification from holding party leadership positions, citing alleged false declarations to ONPE about Juntos por el Perú campaign income and expenses between 2018 and 2020; an audience to determine whether the case proceeds to oral trial is scheduled for May 27, just 11 days before the runoff.
—The Castillo successor framing: Sánchez is positioned as the political continuator of jailed former president Pedro Castillo, who is serving an 11-year-and-five-month sentence for the failed December 2022 self-coup attempt; the 2026 election is widely framed as a “rematch” of the 2021 Fujimori-Castillo contest, which Fujimori lost by 44,000 votes after losing three previous second rounds (Humala 2011, Kuczynski 2016, Castillo 2021).
—The first-round irregularities: The April 12 first round was marked by severe logistical failures including approximately 60,000 voters (principally in Lima) unable to vote due to lack of electoral material, prompting authorities to extend voting to April 13 and ONPE chief Piero Corvetto to resign on April 21; the National Jury of Elections (JNE) ordered a comprehensive informatics audit and López Aliaga has demanded complementary elections in disputed districts.
—The polling: The first runoff polls from IEP and Ipsos show a technical tie at approximately 38% each, contrasting with May 2021 when Castillo led Fujimori by 5-6 percentage points entering the runoff; undecided voters are concentrated among women, young voters, the lowest-income groups and self-identified centrists, with the latter two leaning toward Sánchez and the first two toward Fujimori.
The convergence of a knife-edge electoral race, a fresh prosecution request against the leading left-wing candidate, an institutional crisis at the electoral authority, and Pedro Castillo’s continued imprisonment creates a Peruvian transition scenario in which the eventual winner inherits not only the country’s eighth presidency in a decade but also a legitimacy contestation that begins on June 8.
Who is Roberto Sánchez?
Roberto Sánchez is the candidate of Juntos por el Perú, the left-wing party that supported Pedro Castillo in 2021. Sánchez served as Castillo’s Minister of Foreign Trade and Tourism from 2021 to 2022 and has been the party’s congressional leader since the Castillo removal. He is widely understood to be running on the Castillo coalition’s continuation, with explicit references in his rallies to Castillo banners and political-prisoner framing. His vote map is concentrated in the Andean interior (Cajamarca, Huánuco, Apurímac, Ayacucho, Cusco, Huancavelica) where he typically beat Fujimori by margins exceeding 30 percentage points.
In Cajamarca he won 41% of valid votes, in Huancavelica 43%, in Apurímac approximately 41%, in Amazonas above 36%, and in Huánuco he roughly doubled Fujimori’s vote count. The runoff arithmetic will depend on Sánchez consolidating these interior strongholds while peeling sufficient centrist and urban-women voters in Lima from Fujimori’s coalition, per Perfil.
What is the prosecution request about?
The Second Office of the Second Criminal Prosecutorial Corporation of Lima filed on May 12 a formal request for 5 years and 4 months of prison against Sánchez. The charges are false declaration in administrative procedures and false information regarding political-party contributions during 2018-2020 elections. The prosecutorial thesis is that Juntos por el Perú declared zero campaign contributions for several rounds despite documented bank movements that the prosecution describes as proselytizing activities and fundraising mechanisms.
| Candidate | First-round share | Political orientation |

| Rafael López Aliaga (Renovación Popular) | 11.91% (1,993,656 votes) | Ultra-right, missed runoff by 18,800 votes |
| Runoff date | June 7, 2026 | First IEP/Ipsos poll: 38-38 tie |
| Sánchez prosecution audience | May 27, 2026 | 11 days before runoff |

The Public Ministry alleges that contributions totaling over $57,000 (approximately S/204,951) from Juntos por el Perú members for party activities were not declared to ONPE. A separate strand of the investigation alleges deposits to bank accounts linked to William Sánchez Palomino, the candidate’s brother. The prosecution also seeks permanent disqualification of Sánchez from party leadership positions. The case originated in 2018 and was previously partially archived; the May 12 filing represents a renewed prosecution after partial reformulation, per El Comercio.
How did Sánchez respond?
Sánchez issued a public statement on May 12: “That investigation began in 2018 and accused me of having appropriated party funds. What has the judiciary said after five or six years? Archived. The fraud as a crime in my case has been archived.” He characterized the May 27 hearing as “just another audience, not an oral trial” and described the prosecution as politically motivated. His defense team has argued that the financial reports were prepared by the party treasurer and that Sánchez only signed them in his role as party president, without direct responsibility for the contents. The prosecution counters that his signature validates the documents and creates direct legal responsibility for omissions.
The political reading varies sharply between left and right. Fujimori supporters cite the prosecution as confirmation of opposition concerns about Juntos por el Perú governance. Sánchez supporters frame it as a continuation of the prosecutorial pressure that produced the Castillo trial and conviction. The timing 11 days before the runoff is the central political variable: a guilty determination at the May 27 hearing would directly affect campaign dynamics, while a procedural delay would push the legal resolution past the election.
What is the broader political context?
Peru has had eight presidents in the past decade. The election features 35 presidential candidates, the largest field in the country’s modern history, reflecting the fragmentation of traditional party structures. Keiko Fujimori is making her fourth presidential bid after losses to Ollanta Humala (2011), Pedro Pablo Kuczynski (2016) and Pedro Castillo (2021). All three previous losses were by narrow margins, with the 2021 contest decided by 44,000 votes after a contested recount. The 2026 runoff thus represents both a generational continuation and a structural rematch.
Peru’s macroeconomic fundamentals remain among the strongest in Latin America: investment-grade sovereign rating, manageable public debt, ample reserves, and a central bank with significant institutional independence. However, the political volatility has created persistent risk premia. Lima Stock Exchange (Bolsa de Valores de Lima) sectors most exposed to potential left-wing policy shifts include mining, electricity utilities and banking. A Sánchez victory would likely test investor expectations of continued orthodoxy; a Fujimori victory would face significant governance challenges given her low popularity ceiling and the fragmented congress.
What should investors and analysts watch next?
- May 27 audience outcome: The Preparatory Investigation Court will determine whether the Sánchez case proceeds to oral trial or is archived. A proceed-to-trial decision 11 days before the runoff would dramatically reshape campaign dynamics. An archive decision would remove the legal overhang.
- IEP and Ipsos updated polls: The first runoff polls show a 38-38 technical tie. Watch for any reading above 41-37 in either direction, which would suggest the runoff is no longer competitive. Particular attention to the Lima Metropolitana share, where Fujimori traditionally leads but the prosecution news may shift centrist sympathy.
- López Aliaga voter transfer: The IEP analysis suggests López Aliaga voters lean toward Fujimori. A concrete López Aliaga endorsement of Fujimori before May 25 would solidify the right-wing consolidation; a refusal would create a 12% pool of contested votes.
- Lima sol exchange rate: The sol has been relatively stable through the first-round process. A move above S/3.85 per dollar would signal market expectations of either Sánchez victory or post-election governance crisis; resilience below S/3.80 would suggest the market expects Fujimori or institutional continuity.
- JNE audit results: The National Jury of Elections is conducting an integral informatics audit of the first round. Any finding that materially questions the López Aliaga-Sánchez 18,800-vote gap would force a legal challenge to the runoff configuration itself.
Frequently Asked Questions
Who is Keiko Fujimori?
Keiko Fujimori is the leader of Fuerza Popular, the right-wing party founded by her father Alberto Fujimori, who served as Peruvian president from 1990 to 2000 and was later imprisoned for human rights violations and corruption. Keiko has made three previous presidential bids, losing each in the second round by narrow margins. Her 2026 campaign emphasizes law and order, anti-corruption (a politically complex theme given her own ongoing legal cases), and economic growth.
What is Juntos por el Perú?
Juntos por el Perú is the left-wing political party that supported Pedro Castillo in 2021. After Castillo’s removal and conviction, the party has continued operating as the principal organized left coalition in Peruvian politics. The party emphasizes social-rights expansion, mining-revenue redistribution, and constitutional revision. The internal coalition includes labor-affiliated and indigenous-affiliated groups along with various center-left intellectual factions.
Why did the first round have logistical problems?
The April 12 first round faced severe material shortages, with approximately 60,000 voters (principally in Lima) unable to vote due to missing electoral ballots and other supplies. Authorities extended voting to April 13. ONPE chief Piero Corvetto resigned April 21. The National Jury of Elections (JNE) ordered an integral informatics audit. Rafael López Aliaga and Renovación Popular argue the issues prejudiced their first-round performance and have demanded complementary elections in disputed districts.
What is the connection to Pedro Castillo?
Pedro Castillo, the rural-teacher-turned-president elected in 2021, is serving an 11-year-and-five-month sentence for his failed December 2022 self-coup attempt and corruption charges. Juntos por el Perú, the party that backed Castillo, continues to frame him as a political prisoner unjustly removed. Roberto Sánchez served in Castillo’s cabinet and explicitly positions his candidacy as the continuation of the Castillo political project, with Castillo banners visible at Sánchez rallies.
How does this affect regional politics?
Peru’s election occurs simultaneously with major political transitions across Latin America: Bolivia’s ongoing crisis under Paz Pereira, Argentina’s Adornigate context and risk país above 500, Chile’s first months under Kast, Colombia approaching May 31 first round, and Venezuela‘s debt-restructuring launch. A Sánchez victory would create a clearer left-leaning bloc with Petro-led Colombia and reduce Latin America’s center-right consolidation; a Fujimori victory would align Peru with the Kast-led right-leaning bloc in the Pacific.
