Manuel Bartlett Díaz (born 23 February 1936) is a Mexican politician, former director of the public energy company CFE, and former Secretary of the Interior.

Madrazo and the national leader of the PRI, Mariano Palacios, both condemned these declarations, and announced the possible expulsion of Bartlett from the party.

In 2012 he reentered national politics, being elected a senator for the left-wing Labor Party, in coalition with López Obrador's PRD.

[4][2] In a 3-part article series, investigative journalist Charles Bowden offers eyewitness accounts of Bartlett's involvement (along with other senior Mexican political, law enforcement, security and military officials) in the decision to order the kidnap, torture and murder of American DEA officer Enrique S. "Kiki" Camarena in 1985 in order to shut down his successful campaign against the Guadalajara Cartel.

In these accounts, cartel figures repeatedly mention they expect Bartlett Díaz to one day become President of Mexico, with the implication that they will prosper as a result.
