Cuauhtémoc Cárdenas, loser of a fraud-marred 1988 election, died at 92.

His defeat began what President Sheinbaum called Mexico’s democratic transformation.

Son of Lázaro Cárdenas, the president who nationalised oil, he became Mexico City’s first elected mayor in 1997.

He quit the party he founded in 2014 after 43 students disappeared in Guerrero.

Mexico’s presidency has not said what caused his death.
