Cuauhtémoc Cárdenas, a three-time presidential candidate seen as central to Mexico's transition to democracy, has died in Mexico City at the age of 92, Mexico News Daily reports. The cause of death was not immediately clear.
The son of former president Lázaro Cárdenas, he spent more than 30 years in the Institutional Revolutionary Party before leaving in 1987. He ran for president in 1988 for a left-wing coalition and is widely believed to have won, although the PRI's Carlos Salinas de Gortari was declared the victor. He later co-founded the Party of the Democratic Revolution and stood again in 1994 and 2000.
President Claudia Sheinbaum described him as a man of firm principles who transformed the country's politics, and former president Andrés Manuel López Obrador called him a forerunner of Mexico's democratic movement.
