Claudia Sheinbaum won a landslide victory to become Mexico's first female president, inheriting the project of her mentor and outgoing leader Andres Manuel Lopez Obrador whose popularity among the poor helped drive her triumph.

Sheinbaum, a climate scientist and former mayor of Mexico City, won the presidency with between 58.3 percent and 60.7 percent of the vote, according to a rapid sample count by Mexico's electoral authority. That is set to be the highest vote percentage in Mexico's democratic history.

The ruling coalition was also on track for a possible two-thirds super majority in both houses of Congress.
