THE GUARDIAN WEEKLY: The latest issue features ‘I, Claudia’ – How Mexico’s President Became The World’s Most Popular Leftwing Leader…

Claudia Sheinbaum must be doing something right. With a consistent approval rating of around 70% since becoming Mexico’s president in 2024, the former climate scientist – and protege of her predecessor, Andrés Manuel López Obrador – is the world’s most popular leftwing leader. She is also the first female leader of one of Latin America’s most macho countries.

Yet despite her soaring popularity, driven in part by major universal healthcare reforms, there is a curious tension between Sheinbaum’s disciplined, scientific approach to governing and the messy, often violent politics of modern Mexico. Her handling of the country’s ongoing crisis of disappearances, the continuing influence of organised crime and the rising presence of the army in national life are all issues she has faced criticism over.
