The presiding councilor of Mexico's National Electoral Institute (INE), Guadalupe Taddei, submitted her resignation to the Chamber of Deputies on October 26, 2026, Bloomberg Línea reported. Her departure leaves the body that organizes federal elections without a sitting head as the 2027 electoral cycle approaches.

The letter reached the Political Coordination Board that same Monday, October 26, the day the INE's Internal Control Organ (OIC) sent the Chamber of Deputies a report on its investigations, according to Aristegui Noticias. The document reports 16 case files opened in 2025 and 2026, 11 of them concerning public procurement, with at least 15 current and former public servants, eight individuals and 18 legal entities under investigation. Audit A07-ADQ-2026, notified on October 9, reviewed contracts signed between December 1, 2024 and May 31, 2026 and produced 45 preliminary observation sheets. For Mexico the issue is one of institutional calendar: the INE organizes, tallies and sanctions federal elections, and the General Council needs a sitting presidency to steer the road to 2027.

The institute's ten councilors met on October 26 without reaching agreement on naming an interim head. "There is discomfort because we are facing a crisis of historic character and gigantic dimensions that has to be addressed," councilor Arturo Castillo said, according to Bloomberg Línea. The OIC report adds 20 sanctions issued since January 2025, including 19 disqualifications, 14 of them against officials and former officials, and financial penalties totaling 1.6 million pesos. In three of four case files examined, elements related to the concealment of conflicts of interest were identified. Councilor Carla Humphrey called the questions "extremely serious" and asked that the institute itself be investigated to establish responsibilities.

The Chamber of Deputies must publish the call to designate whoever will hold the post for the six years remaining in Taddei's term, which was due to end on April 3, 2032. The OIC also proposed a national policy on electoral procurement with reference prices and a national catalog of goods, coordinated with the 32 local public electoral bodies.
