BOGOTA, Colombia (AP) — Colombia’s outgoing President Gustavo Petro on Monday reiterated claims of fraud in the nation’s June election, which his party lost narrowly to conservative leader Abelardo de la Espriella. De la Espriella will begin a four-year term on Friday after he is sworn into office in a joint session of Congress. Petro, a longtime critic of Colombia’s political establishment, has refused to acknowledge the results of the June presidential election. However, analysts say that Petro’s claims of electoral fraud could undermine de la Espriella’s legitimacy among some voters and further polarize the nation’s politics. Petro said Monday he feared being “extracted” from Colombia after he steps down from office to become an opposition leader and continues to make claims that Colombia’s election was rigged.
