Leaders of the political opposition have also been implicated in CICIG investigations: several legislators and members of Libertad Democrática Renovada party (LIDER) were formally accused of bribery-related issues, prompting a large decline in the electoral prospects of its presidential candidate, Manuel Baldizón, who until April had been almost certain to become the next Guatemalan president in the 6 September 2015 presidential elections. Baldizón's popularity steeply declined and he filed accusations with the Organization of American States against CICIG leader Iván Velásquez of international obstruction in Guatemalan internal affairs.
