Chamber of Deputies Passes 'Plan B' Electoral Reform; Must Be Enacted by April 30 for 2027 Elections

The Chamber of Deputies approved the electoral reform 'Plan B' on April 9, with the Senate having already passed it in late March. The reform — a fallback after Sheinbaum's original constitutional electoral bill failed in November 2025 for lack of coalition votes — focuses on austerity measures for political institutions: reducing local congress seats, cutting Senate staffing, and aligning political salaries with the government's austerity mandate. The reform must be enacted by April 30 to apply to the 2027 midterm elections. Opposition PAN and Movimiento Ciudadano voted against the measure.
