Isidro Leyva Leyva

Isidro Leyva Leyva (born 1952/1953) is a Mexican trade unionist and politician. He served in the LI Legislature of the Congress of Sonora from 1985 to 1988 as a member of the now-defunct Workers' Revolutionary Party (PRT). He was later the director of the National Cattle Producers' Union from 2005 to 2021.

Career A native of Huásabas, Sonora, Leyva studied law at the Universidad de Sonora (Unison) and began his political activism as a student protester in the 1970s. He joined the Workers' Revolutionary Party (PRT) – a Trotskyist party with origins in the 1968 student protests – and got heavily involved in Sonoran farmers' and peasants' movements. He earned his law degree from Unison in 1982.

Leyva went on a ten-day tour of the Southwestern United States in the weeks leading up to the 1982 Mexican general election, which was the first national election contested by the PRT. The PRT contested its final national election in 1991, after which it lost its registration as a national party. In 2006, Leyva was a pre-candidate to the Chamber of Deputies as a member of the Coalition for the Good of All, which was created by the Party of the Democratic Revolution (PRD), Convergence, and the Labor Party (PT).

A longtime supporter of workers' rights, Leyva was at the forefront of organizations such as the Frente Campesino Independiente Revolucionario and the Unión General Obrero, Campesina y Popular.
