Carlos Alberto Duque Jaén (March 12, 1930 – October 31, 2014) was a Panamanian businessman and politician who was President-for-Life of Panama's Partido Revolucionario Democrático (PRD).
[5] Duque's primary rival for the presidency, Guillermo Endara, ran atop the ticket of the Democratic Alliance of Civic Opposition (ADOC), a coalition of parties opposed to Noriega.
After the voting concluded, international observers reported that Endara's coalition was leading by a 3-to-1 margin, but the results were annulled by the Noriega government before counting was complete.
[6] The next day, Endara and one of his running mates, Guillermo Ford, were badly beaten by a detachment of Dignity Battalions, a paramilitary group supporting Noriega.
[12] Several months after the invasion, US federal prosecutors accused Duque's company, Transit S.A., of funneling millions of dollars in kickbacks to the former ruler from a coffee-smuggling operation.
