A European Union mission that observed Colombia’s presidential election has affirmed the transparency and efficiency of the country’s vote counting process. The mission’s statement comes amid repeated challenges to the results by President Gustavo Petro, whose preferred successor did not win the runoff election.

The independent mission, which deployed approximately 150 observers for Sunday’s runoff, stated that it had “not observed any irregularities” and that Colombian legislation appeared to have been followed. The final results show conservative outsider Abelardo de la Espriella leading by a margin of nearly 251,000 votes, with only a small fraction of ballots remaining uncounted. The EU mission also observed the first round of voting in May.

President Petro and his protégé, progressive candidate Iván Cepeda, are contesting the election results. Petro had previously claimed fraud after Cepeda failed to win the first-round election outright. Cepeda announced that his campaign would challenge the results from over 30,000 voting stations and would not recognize the outcome until a recount is completed. Electoral authorities are expected to finalize the recount this week.

More than 26 million people participated in the runoff election, setting a historic record for voter turnout. A significant number of voters, over 426,000, opted for a third, unnamed choice on the ballot to express dissatisfaction with both candidates. Approximately 29,000 ballots were cast blank.

The election was marked by deep divisions and public anxieties concerning a potential resurgence of the nation's internal conflict. Both candidates presented distinct strategies to mitigate the persistent violence, including car bombs, kidnappings, disappearances, and forced displacements, which have plagued Colombia in past decades.

The winner of Sunday's election is scheduled to begin a four-year term on August 7. The period leading up to the runoff saw heightened verbal exchanges between the candidates, alongside accusations of fraud, vote-buying, and intimidation. President Petro also raised concerns about the software used for vote tabulation.

Esteban González Pons, the chief of the EU observation mission, remarked that it was surprising that the president, who was not a candidate, was denouncing irregularities that the candidates themselves had not reported. The mission is also observing the ongoing recount and plans to release a comprehensive final report in September.
