Weekly Report - 19 March 2026 (WR-26-11)

Mexico’s President Claudia Sheinbaum presented her ‘Plan B’ electoral reform on 12 March, following the lower chamber’s rejection of the original reform initiative. The new proposal, which is also a constitutional reform, is much scaled down from the first iteration, focusing on cutting costs and boosting citizen participation and leaving aside the more controversial aspects of the initial reform. In a big boost for Sheinbaum, the Partido del Trabajo (PT) and Partido Verde Ecologista de México (PVEM), allies of the ruling left-wing Movimiento Regeneración Nacional (Morena), have announced their backing for the new reform after failing to support the previous proposal en masse, likely ensuring its passage through congress.
