Mexico's senate passed a constitutional amendment that adds foreign interference to the list of reasons an election result can be annulled. The amendment defines foreign interference as illicit financing, propaganda, systematic dissemination of misinformation, digital manipulation, or intervention by foreign governments or agencies.

Background and definitions The bill was introduced by President Claudia Sheinbaum. It has already cleared the lower house of congress and now needs approval from a majority of Mexico's 32 states. The governing Morena party controls 24 state legislatures.

Opposition response Opposition parties said the language is broad enough that statements by foreign officials, articles in foreign media, or reports by international organizations could be cited to overturn results. "This is one of the most egregious, alarming and retrograde pieces of legislation in Mexico's young democratic history," former Mexican ambassador Arturo Sarukhan said on X.

"This law doesn't prevent foreign interference. " Senator Ricardo Anaya of the opposition PAN party told reporters the measure would let the ruling party annul any election it chooses.

Context of upcoming elections Mexico is scheduled to hold midterm elections next year. The governing party currently holds the presidency and majorities in both chambers of congress. The country's electoral court was reformed under former president Andrés Manuel López Obrador and is now largely aligned with Morena.

Sheinbaum said at a Thursday news conference that all Mexicans should agree there should be no foreign interference in elections and that Mexicans alone decide who governs them.
