LIMA — Peru's public prosecutor's office on Tuesday accused leftist presidential candidate Roberto Sanchez of filing false financial disclosures and called for him to be imprisoned for five years and four months. Prosecutors are also seeking a permanent disqualification barring Sanchez from holding the office of president for the Juntos por el Peru party.

The charges, unsealed Tuesday, allege that Sanchez filed false financial disclosures with the National Office of Electoral Processes related to campaign contributions. The alleged conduct spans 2018 through 2020. Prosecutors say Sanchez and his brother, William Sanchez, received more than 280,000 Peruvian soles ($81,720) in contributions and membership fees that were never disclosed in the party's financial filings.

Sanchez is also accused of making false statements in administrative proceedings. A judge is expected to decide on May 27 whether the case will go to trial.

Sanchez's lawyer rejected the accusations. In a statement, the lawyer said, "The party's treasurer, not Sanchez, was responsible for its financial filings."

The charges were unsealed as electoral authorities confirmed Sanchez was on track to advance to the presidential run-off scheduled for June 7. Vote counting from the first-round election showed him advancing to a run-off against conservative rival Keiko Fujimori. With 99.76 percent of ballots counted, Fujimori held a lead with 17.17 percent of the vote. Sanchez stood at 12 percent, while Rafael Lopez Aliaga trailed at 11.91 percent, a margin of roughly 15,000 votes behind Sanchez. The final result of the first-round election is expected by May 15.

Fujimori, the daughter of late former President Alberto Fujimori, is a four-time presidential candidate. Sanchez is running with the backing of jailed former President Pedro Castillo.
