Early political career In the
1995 general election, he unsuccessfully ran for Congress for the socialist party Apertura para el Desarrollo Nacional, obtaining 1019 votes. López Chau temporarily joined
Union for Peru in 2010. He was elected by
Congress to serve as a director of the
Central Reserve Bank of Peru (BCRP) under chairman
Julio Velarde for the period of 2006–2013. He agreed to host delegations of university students protesting during the
Toma of Lima marches at the university facilities. In late January 2023, the youth protesters from southern Peru began to promote a possible presidential candidacy for López Chau. In February 2023, in the context of discussions about possible snap
congressional election, there were suggestions that López-Chau would become the
Purple Party's presidential candidate; a few days later, he confirmed dialogue and negotiations with the party, but made it clear that he would not be the organization's candidate in order to continue to adhere to his own democratic principles. On 19 July 2023, he participated in the Third Toma of Lima. In July 2025, the
Public Ministry of Peru opened investigations on López Chau for alleged
collusion and incompatible negotiation. He faced investigations regarding allegedly appointing Sonia Anapan Ulloa as general secretary, despite her not meeting the requirements of the university statutes and simultaneously holding a position at SINEACE (National System for Evaluation, Accreditation, and Certification of Educational Quality), which would violate public service regulations. Furthermore, her appointment was reportedly not approved by the university council. The Ministry also pointed to a salary increase granted to Anapan in less than three months, considered a possible case of undue favoritism. For these acts, a sentence of five years' imprisonment, a fine, and a twelve-year disqualification from holding public office was requested for both. In June 2024, he officially announced his presidential aspirations and stated that he sought to contribute to the creation of a broader coalition of different political parties for the upcoming
2026 general election. He declared that his electoral campaign will be conducted in Spanish and in indigenous languages such as
Quechua,
Aymara, and
Asháninka. On Sunday, 1 February 2026, he began his presidential campaign in the city of
Juliaca, holding a political rally in the city's main square. == Political positions ==
