Keiko Fujimori Higuchi took office as president of Peru on July 28, 2026, after winning the runoff by a margin of just 49,641 votes over Roberto Sánchez. It was her fourth presidential bid. She comes to office with 69 prosecutorial investigations on her record —51 closed, 18 ongoing—, almost all of them stemming from the “Cócteles” case: the investigation into the irregular financing of her 2011 and 2016 campaigns, which includes acknowledged contributions from the Brazilian construction company Odebrecht. This file reviews the documented findings about her political career.

Table of findings

The “Cócteles” case — financing of the 2011 campaign

In September 2011, the National Office of Electoral Processes (ONPE) documented that Fuerza Popular (known at the time as Fuerza 2011) reported earnings surpassing S/17 million for that presidential race, featuring a significant amount of transfers from unknown sources. The political organization accounted for a portion of that sum through a pair of gatherings: a cocktail reception in December 2010 that allegedly brought in roughly US$119,750 alongside a second event that same month valued at approximately US$90,000. Ever since 2014, the Prosecutor’s Office has argued that such fundraisers and sweepstakes could not have financed an operation of that magnitude, contending they actually concealed a ring of “simulated contributors,” commonly referred to as “pitufeo” (smurfing)—namely, entrepreneurs who lent their identities to mask the genuine source of the funds. El Comercio reported that Fuerza Popular’s legal team admitted during the trial to the existence of these fictitious donors, while nevertheless rejecting the claim that such actions amounted to money laundering.

Credicorp’s Dionisio Romero, with about US$3.65 million, and Juan Rassmuss of Sudamericana de Fibras appear among the identified contributors, Resumen Latinoamericano reported. Jorge Barata, who represented Odebrecht in Peru, told Peruvian prosecutors in February 2019 that the Brazilian builder had given US$1.2 million to the 2011 campaign by way of Jaime Yoshiyama, according to RPP. In addition, Marcelo Odebrecht’s notebook, disclosed in 2017, contained a note about “increase Keiko,” as cited by El Comercio.

The “Cócteles” case — financing of the 2016 campaign

The same investigation was extended to the 2016 presidential campaign, in which Fujimori lost the runoff to Pedro Pablo Kuczynski by a razor-thin margin. According to Resumen Latinoamericano, in 2016 José Chlimper Ackerman, then secretary general of Fuerza Popular, reportedly collected US$480,000 in five deliveries, money whose final destination was not established in the prosecutors’ case file. A 2018 report by the Money Laundering Prosecutor’s Office concluded that the party was able to account for only 33% of the money raised across both campaigns.

The Prosecutor’s Office, with prosecutor José Domingo Pérez in charge, maintains that Fujimori and the Fuerza Popular leadership used the same mechanism of simulated contributors in 2016 to conceal the origin of the funds, as reconstructed by El Comercio. Among those summoned to testify was former congressman Rolando Reátegui, who entered into a cooperation agreement (colaboración eficaz) and described how he recruited fake contributors in the San Martín region at the request of the party leadership, according to Epicentro.

Preliminary detention and pretrial detention (2018-2019)

In October 2018, Fujimori was held in preliminary custody for a ten-day period as the Prosecutor’s Office examined suspected money laundering tied to the cocktail fundraisers and raffles organized by Fuerza 2011, as reported by Al Jazeera. Several months afterward, magistrate Richard Concepción Carhuancho approved a request from prosecutors for pretrial detention citing potential obstruction of the probe, leaving Fujimori detained at the Anexo de Mujeres facility in Chorrillos for upwards of 13 months, according to La República. Prosecutors maintained at the time that Fujimori “directs, leads and coordinates” the operations of a criminal organization inside her political group. This decision was subsequently reassessed, allowing Fujimori to secure her release, even though she stayed bound by several limitations (comparecencia, a travel prohibition) while the legal proceedings progressed.

Trial and the prosecution’s indictment (2024-2025)

The “Cócteles” trial got under way on July 1, 2024, with Fujimori, her former partner Mark Vito Villanella and 44 other people as defendants, according to Infobae. She stood accused of criminal organization, money laundering, obstruction of justice and false statement in an administrative proceeding. As El Comercio reports, the indictment review stage that preceded the trial lasted one year and nine months under judge Zúñiga, with more than 13,000 pages in the prosecutors’ file; prosecutors, the outlet adds, asked for 30 years and 10 months in prison for ex-advisers Pier Figari and Ana Herz, and for 22 years and 8 months for Vito Villanella.

That same case file records that a protected witness said Figari and Herz took money from businesspeople who wanted to stay off the official list of 2011 campaign contributors. Throughout the proceedings, Fujimori’s defense argued that the Prosecutor’s Office would not manage to prove money laundering.

Trial annulled by the Constitutional Court (October 2025)

Back in October 2025, even as the legal proceedings remained ongoing, the Constitutional Court (TC) voided the judicial process that had kicked off back in 2024. As highlighted by La Válvula, the TC determined that the Prosecutor’s Office had repeatedly amended its indictment in a manner that undermined the accused parties’ right to due process. Rather than ruling on whether the irregular financing actually took place, the decision centered on various procedural flaws attributed to the Public Prosecutor’s Office throughout the lengthy investigation.

Definitive dismissal of the case (January 2026)

In January 2026, the Constitutional Court ordered the dismissal of the money laundering and criminal organization charges over the contributions received in the 2011 and 2016 campaigns, according to La Válvula. The rationale, as reconstructed by El Comercio, was that at the time of the events under investigation (2011 and 2016), irregular party financing was not classified as a standalone crime —that offense only took effect in 2019— and that the existence of a criminal organization within the party had not been proven either. The same procedural route had previously benefited Pedro Pablo Kuczynski, whose case over Odebrecht contributions was also dismissed in 2026, which prompted a public complaint from Ollanta Humala, convicted for similar acts and still in prison.

This dismissal closes, at least within the criminal courts, the judicial front that defined Fujimori’s political trajectory for over a decade.

Unsubstantiated electoral fraud claim (2021)

After losing the 2021 runoff to Pedro Castillo by a margin of 0.25 percentage points, Fujimori initially refused to recognize the result, alleged fraud and filed hundreds of requests to annul tally sheets and votes, according to Wikipedia. The National Elections Jury (JNE) rejected those challenges and proclaimed Castillo the winner on July 19, 2021; only then did Fujimori announce that she would abide by the result.

International electoral observation bodies, including the Organization of American States and the European Union, concluded that the election had been clean and competitive, according to La Válvula. No irregularity was documented that would support the fraud claim on the scale needed to overturn the result.

Appointment of people formerly under investigation to her government (September 2026)

On September 16, 2026, now as president, Fujimori appointed Jaime Yoshiyama Tanaka, José Chlimper Ackerman and Arsenio Oré to an Advisory Commission of the Presidential Office, according to La República. Yoshiyama was identified by the Prosecutor’s Office as the person who, according to Jorge Barata’s testimony, received and concealed Odebrecht’s contributions to the 2011 campaign; Chlimper, the party’s secretary general at the time, was investigated for the same crimes attributed to Fujimori (criminal organization, money laundering, false statement and generic falsification). Both had been ministers during the government of Alberto Fujimori.

Since the case was dismissed in January 2026, none of the three is facing pending charges in the “Cócteles” case anymore; even so, the appointment reopened questions about how close the president is to the circle singled out in the case that marked her career.

Clash with the Judiciary over her UN speech (September 2026)

On September 22, 2026, before the United Nations General Assembly, Fujimori stated: “we defeated terrorism, but unfortunately even today, after 34 years, those who took on that mission are still being prosecuted, despite it having been shown that due process was violated,” according to Infobae. The president of the Judiciary, Janet Tello, “completely” rejected those words, and recalled that judges were also murdered in the fight against terrorism and that it was judges who convicted Abimael Guzmán.

Fujimori did not back down. As Infobae reported, her answer was that she would not “stay silent” about “the mistakes of the past.” With that exchange, her government and the head of the Judiciary entered their first public confrontation.

Annex: open investigations without indictment or judgment

The following investigations remain open and have not led to an indictment or a judgment. They are included as part of her legal record, not as proven facts. Since she took office, Article 117 of the Constitution limits the progress of investigations against her during her term, according to Gestión.

Inquiry regarding contributions made to the 2021 campaign

On September 30, 2025, the First Supraprovincial Corporate Prosecutor’s Office Specialized in Money Laundering Crimes formalized a preparatory investigation against Fujimori, Luis Galarreta, Miguel Torres, Lidman Miranda and Fuerza Popular as a legal entity, whom it accuses of forming a criminal organization to launder assets through the contributions to the 2021 campaign, according to RPP. The term is 36 months, and judge Wilson Verástegui ordered only simple appearance (comparecencia simple).

According to Infobae, the prosecution’s theory includes false donations of undeclared origin, the use of S/1.6 million in public financing for campaign purposes, and the collection of S/1,258,708 between July 9 and 30, 2021, to challenge Pedro Castillo’s victory. Several contributors denied having made the donations attributed to them. There is no indictment or judgment.

The Alas Peruanas case

As part of a probe distinct from the “Cócteles” inquiry, the Public Prosecutor’s Office attributes to Fujimori and her ex-advisor Pier Figari the alleged commission of aggravated money laundering, utilizing funds allegedly originating from Universidad Alas Peruanas as well as the organization attributed to its founder, Fidel Ramírez, who is the father of former Fuerza Popular secretary general Joaquín Ramírez. According to La República, the prosecution’s hypothesis encompasses S/210,000 obtained in 2011, S/54,536 spanning 2014 and 2015, alongside a pair of real estate conveyances in Lima.

On April 30, 2025, the Fourth National Preparatory Investigation Court incorporated Fuerza Popular as a legal entity, although Gestión subsequently reported that an appeals chamber declared that addition unlawful and dismissed the political party from the case. The proceedings involving the natural persons remain open, with no indictment.

Illicit enrichment investigation (2026)

On February 4, 2026, weeks after the dismissal of the “Cócteles” proceedings, reports revealed that Lima’s First Provincial Corporate Prosecutor’s Office Specialized in Public Corruption Crimes had launched a probe into Fujimori concerning illicit enrichment, as reported by Infobae. Investigators are centering their attention on the US$3.6 million in cash allegedly given to her by Dionisio Romero across the period from November 2010 to May 2011; authorities point out that her official financial disclosures as a congresswoman for 2010 and 2011 showed virtually no variation despite the injection of those funds.

Unlike the dismissed case, which centered on party financing, this investigation examines her personal assets. It was classified as complex, with an initial term of eight months. There is no indictment.
