Key Facts

- —Why it matters The INE runs Mexico’s elections, and the vote on Sunday, 6 June 2027 fills 19,609 posts, including 500 federal deputies and 17 governorships. Its leader is leaving about seven months before that.
- —The numbers Outlets report INE contracts with the suppliers in question of 198 million pesos (US$10.6 million) in 2024 and at least 240 million pesos (US$12.8 million) in tenders. The figures differ, and none is proven.
- —Who is who Taddei has led the INE since April 2023. The Superior Audit Office (ASF) is Congress’s auditor, and the Chamber of Deputies must name her permanent successor.
- —What to watch Whether the Chamber accepts the resignation and names a successor, which councillor serves as interim, and what the ASF audit of INE contracts finds.
- —Power Index Mexico ranks 2nd of 14 in The Rio Times Latin America Power Index, with 71.4 points (October 2026 edition).
- —What it means for you Travel and trade are not affected so far. Anyone following Mexico’s 2027 midterms should watch whether the INE keeps its election calendar.
The head of the agency that runs Mexico’s elections says she is stepping down. Auditors are examining supplier contracts.
Guadalupe Taddei, president of Mexico’s National Electoral Institute (INE), said on Sunday, 25 October, that she will resign. She plans to hand her resignation to the Chamber of Deputies on Monday, 26 October.
The INE organises Mexico’s federal elections, and the next one is on Sunday, 6 June 2027. Her exit follows reported claims of conflicts of interest in INE contracts, which she calls unverified.
What Taddei Said
Taddei called the reports “trascendidos, montajes, filtraciones y versiones”, meaning hearsay, set-ups, leaks and versions that must still be verified. She said she is leaving to protect the institute, according to the INE statement of 25 October.
She added that her exit does not excuse anyone from clarifying the facts. She also said she has served the electoral system for 33 years, the same INE statement says.
On Saturday, 24 October, the INE presidency said it would cooperate with the ASF and sent its files to internal oversight. It added that it had itself asked for an audit of its tender processes.
What Is Alleged
Reforma reported on 19 October, as relayed by Expansión, that Taddei’s driver is legal representative of Corporativo Zeg, an INE supplier. Excélsior says Zeg and a second firm, Cajas Graf, hold INE contracts that raised questions.
El Financiero reports videos showing Taddei with businessman José Alfredo Hernández Casillas. Excélsior calls him an INE electoral supplier who owns firms with INE contracts.
Excélsior puts his firms’ INE contracts at 198 million pesos (US$10.6 million) for 2024. El Financiero says he holds at least 240 million pesos (US$12.8 million) in INE tenders.
Reforma, as relayed by El Imparcial, says the finance ministry’s financial intelligence unit (UIF) investigated both firms and froze their accounts. These are reports, not court findings, and conversions here use about 18.72 pesos per US$ on 26 October 2026.
What the Audit Office Is Doing
Excélsior and Tribuna de la Bahía report that the ASF opened an investigation on its own initiative on Friday, 23 October. It covers the INE, local electoral bodies, public officials and suppliers.
Neither report finds Taddei or any company liable. Tribuna de la Bahía notes that the claims do not yet amount to a finding of administrative or criminal responsibility.
How Politicians Reacted
President Claudia Sheinbaum asked the INE around 20 October to clarify the contracts, Expansión and El Imparcial reported. El Financiero adds that she said there must be “no shadow of corruption”.
Party representatives on the INE General Council asked her to explain and to leave her post, El Financiero reported. Ricardo Monreal, Morena’s leader in the Chamber of Deputies, asked the INE’s internal control body to investigate, El Imparcial reported.
Who Replaces Her
The Chamber of Deputies, Mexico’s lower house, appointed Taddei in April 2023 for nine years, INE and Tribuna de la Bahía say. Excélsior says the Constitution has the Chamber name a replacement to finish the term.
Meanwhile the ten remaining councillors could elect one of themselves as interim president by majority vote, Excélsior and Expansión reported. No successor has been officially named.
In Plain English
The INE is Mexico’s independent election agency, and its president chairs an 11-member General Council. The council oversees the 2026-2027 process that began on 10 September, according to Uno TV.
The ASF is the audit arm of Congress, and the UIF is the finance ministry’s financial intelligence unit. Neither has found Taddei guilty of anything.
What It Means for US Readers
Mexico is a close neighbour and trading partner of the United States, so its election agency matters to investors. No effect on travel, trade or the peso has been reported.
The INE says its work toward the 2027 midterms continues as planned. Background is in the Mexico politics explainer and in the earlier report on the INE council warning.

What Is Not Known
No outlet found by this newsroom confirms yet that the resignation has been filed or accepted. Taddei said in the INE statement she would file it on Monday, 26 October.
No successor or interim president is named, and the ASF has published no findings. The contract totals also differ between outlets, at 198 million and 240 million pesos.
The ASF release itself was not opened, so the audit rests on Excélsior and Tribuna de la Bahía. No reply from Hernández Casillas, the driver or the two firms was found.
What Comes Next
The next step is the filing in the Chamber of Deputies and the choice of an interim president. The ASF audit then continues, and the electoral process runs toward the vote on 6 June 2027.
The resignation does not prove any wrongdoing, and it does not end the audit. Taddei herself said the facts must still be clarified.
