International observers certify Colombia’s first-round vote as transparent and credible

Two major international electoral observation missions have rejected claims of fraud in Colombia’s May 31 presidential first round, as outgoing President Gustavo Petro continued to press unsubstantiated allegations of irregularities in the days following the vote. The country heads to a June 21 runoff between right-wing candidate Abelardo de la Espriella and leftist senator Iván Cepeda.

The European Union Election Observation Mission (EU EOM) issued a preliminary statement Tuesday, June 2, describing the vote count as having been carried out in a “transparent, orderly and fluid” manner. Esteban González Pons, Vice President of the European Parliament and chief observer of the EU mission, told reporters in Bogotá that none of the 12 candidates who competed in the first round had brought claims of irregularities to his mission.

“We can discard any manipulation of data in the quick count and in the final count,” González Pons said. The mission selected a random sample of tally sheets from around the country and compared them to physical ballots cast, finding no inconsistencies.

The EU EOM deployed 143 observers from 24 EU member states plus Norway, Switzerland, and Canada, covering 591 voting tables. The mission will also observe the June 21 runoff and issue a final report two months after the process concludes.

The Organization of American States (OAS) mission, headed by former Dominican Republic President Leonel Fernández, similarly described the May 31 election day as “civic, calm and participatory,” with high citizen turnout compared to previous electoral cycles. The OAS mission comprised 96 observers and specialists from 24 countries, covering 412 polling stations and 1,340 voting tables across 26 departments, the Capital District, and five cities abroad.

Official results from the National Civil Registry (Registraduría Nacional del Estado Civil) showed de la Espriella receiving 43.74% of the vote, a margin of more than 673,000 votes over Cepeda, who received 40.90%. More than 23 million voters participated. By Monday night, the Registry said it had completed its review of 99.98% of voting tables and found a variation of only 0.06% from the quick count issued on election night.

Petro, who is constitutionally barred from seeking re-election, alleged on Sunday that 800,000 voters had been illegally added to voter rolls. He doubled down Tuesday in a post on X, claiming without evidence that 885,000 voters had been registered after a March 31 deadline, and pointing to alleged irregularities in the software used for vote counting and tabulation. The president said he could present his evidence to the relevant authorities.

Cepeda, who represents Petro’s Pacto Histórico, initially declined to acknowledge the quick count results on Sunday, saying he would wait for the official tally overseen by judges and notaries. By Monday, however, he softened his position, stating that monitors deployed by his party had not found “irregularities of a sufficient dimension to speak of fraud.” Cepeda also challenged de la Espriella to a debate ahead of the runoff.

Under Colombian law, election results are certified by judges, not the executive branch, typically within two weeks of the vote. González Pons noted that Colombia “has very strong democratic institutions, rooted in the people,” adding that the country “will find in democracy its principal ally, because of all the things that fail Colombia, democracy is one that has never failed it.”

Political analysts and observers have cautioned that Petro’s fraud allegations, made without supporting evidence, risk inflaming political tensions and contributing to a polarized climate in the lead-up to the June 21 runoff.

A June 21 presidential runoff will decide Colombia’s next president

Far-right candidate Abelardo de la Espriella and leftist Iván Cepeda advanced to the runoff round of Colombia’s presidential election after emerging as the top vote-getters in the May 31, 2026, first-round vote, in a result that reflects the deep political polarization shaping the country.

With 99.99% of polling stations counted, the Registraduría Nacional del Estado Civil reported that De la Espriella won more than 10.3 million votes (43.7%), while Cepeda secured 9.6 million votes (40.9%). The two candidates will face each other in a runoff election scheduled for June 21, 2026.

Voter turnout reached 23.7 million people, equivalent to 57.8% of eligible voters. Together, the two candidates captured nearly 85% of valid ballots, leaving the remaining contenders far behind and setting up a contest between two sharply contrasting political visions.

De la Espriella’s unexpected rise

De la Espriella’s first-round victory represents one of the biggest surprises of the election and marks the first time in Colombia’s modern political history that a far-right party has emerged with a realistic chance of winning the presidency.

A lawyer by profession with no previous elected office experience, De la Espriella built his campaign around a populist message focused on political confrontation, public security, a hard-liner approach to crime and opposition to negotiations with illegal armed groups. His political style has drawn comparisons to Argentine President Javier Milei, Salvadoran President Nayib Bukele and US President Donald Trump.

Most pre-election polls placed him in second or third position, with support ranging between 15% and 25%, well below his final result.

His platform emphasizes stronger security policies, tougher penalties for criminal and narcotraffic organizations, and the construction of large-scale prisons similar to those in El Salvador. He has also rejected peace negotiations with armed groups.

His opposition to diversity and inclusion policies, as well as controversies involving remarks toward female journalists for which he later apologized, also became defining features of his campaign.

Cepeda achieves the strongest result ever for Colombia’s left party

Although he finished second, Cepeda achieved the highest vote total ever received by a left-wing presidential candidate in Colombia, surpassing the 8.5 million votes won by President Gustavo Petro in a previous presidential election.

The candidate of the ruling Pacto Histórico party based his campaign on grassroots mobilization, public rallies and the consolidation of a unified left-wing movement. His message focused on expanding social programs, inclusion and reducing inequality.

However, his candidacy has also been weighed down by criticism of the current administration, particularly regarding security concerns, problems within Colombia’s healthcare system and the limited results of the government’s “Total Peace” policy, which Petro promoted and Cepeda supported during his years in Congress.

Cepeda’s political career has been built in Congress, where he became known for defending the rights of victims of paramilitary violence and for his role in legal cases involving former President Álvaro Uribe.

After preliminary results were released, both Cepeda and Petro publicly questioned the preliminary vote count while stating they would recognize the official results certified by electoral commissions, judges and notaries.

“As president, I do not accept the preliminary count results,” Petro wrote on X, arguing that Colombia’s pre-count system has no legal validity and that only the official scrutiny process produces binding results. He later added that “the binding results the president will recognize are those issued by the electoral scrutiny commissions.”

Cepeda has also sought to distance himself from some of Petro’s proposals, including the idea of convening a constituent assembly to revise Colombia’s constitutional framework.

Historic defeat for Uribe’s political movement

Another major statement of the election was the poor performance of Paloma Valencia, candidate of the Centro Democrático party and backed by former President Uribe, who campaigned alongside her throughout the country despite defections by several prominent supporters.

Valencia finished third with 1.6 million votes (6.9%), far below polling projections that had placed her above 20%.

The result is widely attributed to voter fatigue with Uribe’s political movement and the migration of conservative voters toward De la Espriella, who was endorsed during the campaign by several prominent right-wing figures, including senators Paola Holguín and María Fernanda Cabal, as well as leader and businessman José Félix Lafaurie.

Strategic decisions within Valencia’s campaign may also have contributed to the result, including the selection of former Bogotá councilman Juan Daniel Oviedo as her vice-presidential running mate and her reluctance to directly confront De la Espriella during the campaign.

This marks the second consecutive presidential election in which Uribe reaches the runoff without a candidate from his own party. Nevertheless, he quickly endorsed De la Espriella after the results became known.

That endorsement could prove crucial. If elected, De la Espriella would face a Congress in which his movement holds only limited representation, making support from Centro Democrático, the second-largest congressional bloc, essential for advancing legislation and reforms.

Centrist voters may decide the runoff

Former Medellín Mayor Sergio Fajardo, who campaigned as a centrist alternative, finished fourth with more than 1 million votes (4.2%), while none of the remaining candidates surpassed 1% of the vote.

As the runoff approaches, the votes won by both Valencia and Fajardo are expected to be closely watched by the two campaigns, as they could prove decisive in an election that is shaping up to be highly competitive, deeply polarized and politically fragmented.

While Valencia has already endorsed De la Espriella, Fajardo has yet to take a public position. In previous elections, the former Medellín mayor has preferred to leave his supporters free to decide rather than formally endorse either finalist.

In Valencia’s case, despite her endorsement of De la Espriella, it remains unclear whether her support came primarily from voters aligned with former President Álvaro Uribe or whether a significant share was driven by the candidacy of Juan Daniel Oviedo, who won more than 1.2 million votes in the coalition primaries held in March.

The June 21 presidential runoff will therefore pit two sharply different visions for Colombia’s future against one another, in a political environment marked by polarization, social tensions, and persistent challenges related to security and governance that the next administration will have to address.
