Overview
- Taddei formally submitted her letter of resignation to the Chamber of Deputies on Monday, Oct. 26, 2026, saying she steps down to protect the institute and preserve calm.
- The INE's ten consejerías met in an emergency session but did not reach the majority needed to name a provisional president and will reconvene to select interim leadership.
- The Auditoría Superior de la Federación has opened an investigation de oficio into INE and state electoral procurement and the Órgano Interno de Control had been probing suspected influence peddling and conflicts of interest for months.
- President Claudia Sheinbaum and Morena leader Ricardo Monreal publicly backed Taddei's exit and urged quick personnel reviews and removals of officials tied to the supplier allegations to restore trust.
- The case raises election integrity risks ahead of the June 6, 2027 vote because unresolved audits and opaque contracting could undermine public confidence; readers should watch for public OIC and ASF findings, transparent vendor records on the INE microsite, and who the Chamber of Deputies names as the permanent replacement.
