Former Colombian Foreign Minister Álvaro Leyva Durán launched a blistering attack against President Gustavo Petro just days before Colombia heads to the polls on May 31, warning of what he described as looming threats to the country’s democratic institutions and accusing the government of preparing to reject an unfavorable electoral outcome.

In a lengthy manifesto published Tuesday on the social media platform X under the title “Propuesta de Álvaro Leyva Durán al País para las Elecciones,” the veteran Conservative politician claimed Petro fears both political defeat and possible legal consequences should right-wing presidential candidate Abelardo De la Espriella emerge victorious.

“Petro knows that his future depends on his successor protecting him from justice,” Leyva wrote, adding that De la Espriella “could win the elections in the first round.”

According to Leyva, the former member of the M-19 guerrilla and senator understands that with De la Espriella in office, “he himself could end up in prison. And that is why he has sought to derail the candidate and will refuse to recognize his victory.”

The explosive accusations mark the latest escalation in the increasingly bitter campaign season ahead of what analysts are calling one of Colombia’s most polarized elections in decades. Leyva, once one of Petro’s closest political allies and his first foreign minister, has in recent months become one of the president’s fiercest critics.

In the manifesto, Leyva intertwined personal memories of Colombia’s turbulent political history with warnings about what he believes is unfolding behind the scenes of the current administration.

“At my age, I know these kinds of stories well,” he wrote, before recalling his close relationship with slain Conservative leader Álvaro Gómez Hurtado.

“My father, Jorge Leyva, gave me at birth the name of his friend Álvaro Gómez Hurtado. When I was 12 years old, Álvaro would speak to me about politics and explain the world to me with a globe.”

Leyva recounted how Gómez and his own father were exiled after the 1953 military coup, and how decades later he worked alongside Gómez politically, even helping negotiate his release after he was kidnapped by the M-19 guerrilla movement in 1988.

“In 1995, after leaving a lecture at Sergio Arboleda University, Álvaro Gómez and I shook hands for the last time,” Leyva wrote. “Because minutes later, I watched in horror as he was assassinated in his car. It was a national tragedy.”

The former minister used Gómez’s legacy as a contrast to his eventual disillusionment with Petro.

“Because of that, I believed I could work with Gustavo Petro,” he said. “When he invited me to become his minister, I accepted because I believed him to be an honorable man. But I was wrong.”

Leyva then delivered some of his harshest remarks yet against the president.

“I came to know the monster from within: his vileness and degradation,” he wrote. “At enormous personal and family cost, I dared to denounce his baseness and his disrespect for the office.”

He added: “Because character demands that one not remain silent in the face of ignominy. And because of everything I witnessed, because of the rotten environment in which he (Petro) moves, I know what the government is plotting.”

Leyva also alleged that Petro’s radicalised supporters to intimidate opponents and manipulate the electoral process. “Today, while Abelardo wages a major democratic battle, Petro incites his followers to commit all kinds of outrages,” he wrote. “There has even been talk of snipers during the campaign.”

Without providing evidence, Leyva claimed that attempts had been made to invalidate De la Espriella’s candidacy, suppress favorable polling data and mobilize state-backed political machinery to influence the vote.

“On election day, rivers of money will flow in an attempt to stop De la Espriella,” he warned.

The former foreign minister also accused Petro of laying the groundwork to dispute the legitimacy of the election itself.

“The president has also spent months constructing a narrative of electoral manipulation,” Leyva wrote. In this way, according to the author, he is “weaving an argument to reject an adverse electoral outcome” that he already senses is inevitable. “That is the false ace up Petro’s sleeve,” he continued. “And like any gambler fueled by hatred, he will use it.”

Leyva also referenced U.S. Republican lawmakers from Florida, María Elvira Salazar and Rick Scott, claiming both were aware of the risks facing Colombia’s democratic process. “Scott is an ally of Colombian democracy and correctly sensed what the national government is planning,” he wrote.

In one of the most dramatic sections of the manifesto, Leyva proposed that Petro temporarily step aside if he alleges fraud after either the first or second round of voting.

“I make a proposal: if in the first or second round Petro claims there was fraud, he should step down from office under the terms of Article 193 of the Constitution,” Leyva wrote.

He suggested that the vice president temporarily assume office while an international commission made up of U.S. lawmakers, European parliamentarians, the Vatican and the United Nations review the vote count and oversee the transition of power before August 7.

“Think about it, Gustavo. Think about it carefully,” Leyva concluded. “Because the alternative will not end well for you. Abelardo De la Espriella will be the next president. And you will have to accept that reality, whether you like it or not.”

Colombia entered the final week of campaigning on Monday ahead of a presidential election that has exposed deep political divisions, sharpened ideological tensions and raised concerns over the country’s security and economic future.

The three leading candidates in the 2026 race wrapped up major public appearances over the weekend with rallies across Bogotá, where supporters waving flags, chanting slogans and wearing campaign colors filled arenas, public plazas and avenues in a final push before Sunday’s first-round vote.

The election has increasingly become a referendum on the legacy of President Gustavo Petro and the future direction of the South American nation after four years marked by failed social reforms, diplomatic friction, fiscal pressures and a deteriorating security conditions ahead of the May 31 election.

Senator Iván Cepeda, the candidate aligned with Petro’s governing Historic Pact coalition, entered the final stretch of the campaign presenting himself as the defender of progressive reforms and social justice policies aimed at reducing inequality and expanding access to education, pensions and healthcare.

Speaking before supporters in Bogotá’s historic Plaza de Bolívar, Cepeda urged Colombians to “defend hope” and reject what he described as a return to the political establishment that governed Colombia before Petro’s historic 2022 victory.

“Our project is one of dignity, peace and social transformation,” the hard-left senator told supporters. “We cannot allow fear and hatred to reverse the changes that millions of Colombians demanded.”

Cepeda has pledged to continue the government’s controversial “Total Peace” strategy, which seeks negotiated settlements with armed guerrilla groups and criminal organizations. The policy, however, has failed to curb violence and has instead allowed illegal armed factions to strengthen territorial control in rural areas.

Security has emerged as one of the defining issues of the campaign following a rise in massacres, attacks against security forces and extortion in regions including Catatumbo, Cauca and parts of the Pacific coast. Several recent bomb attacks and clashes involving dissident rebel groups have intensified public anxiety and become central talking points for opposition candidates.

Conservative lawyer and political outsider Abelardo de la Espriella has capitalized on growing frustration over insecurity, presenting himself as the candidate of “authority and order.”

During rallies attended by thousands in Bogotá, Barranquilla and Medellín, de la Espriella has promised a sweeping security crackdown against illegal armed groups, tougher prison sentences and expanded support for the military and police.

“Colombia cannot continue surrendering territory to criminals and terrorists,” he told cheering supporters. “The state must recover authority in every corner of the country.”

De la Espriella has also sought to attract business leaders and middle-class voters concerned about inflation, unemployment and slowing investment. His campaign platform includes proposals for tax reductions, deregulation and incentives aimed at restoring investor confidence after several years of economic uncertainty.

Meanwhile, senator Paloma Valencia closed her campaign with a massive event at Bogotá’s Movistar Arena, in which she framed the election as a battle to prevent Colombia from drifting toward authoritarianism and economic collapse. Throughout the campaign, she has repeatedly warned voters against what she calls “the Venezuelanization of Colombia,” a message that has resonated strongly among conservative sectors and business elites.

“We are voting for democracy, liberty and the survival of our institutions,” Valencia said during her closing rally. “Colombia cannot continue down the path of division and improvisation.”

Political analysts say the election reflects a country increasingly polarized between those who support Petro’s promise of structural change and those who believe the administration’s policies have weakened institutions, damaged investor confidence and emboldened armed groups.

Recent polling suggests Cepeda maintains a narrow lead heading into Sunday’s vote, though few observers expect any candidate to secure the more than 50 percent needed to avoid a runoff election scheduled for June 21.

The latest surveys indicate a highly competitive contest for second place between Valencia and de la Espriella, setting the stage for what could become one of the most polarized second-round races in Colombia’s modern political history.

Beyond ideology, many voters say they remain concerned about rising living costs, access to employment, corruption and public safety.

In downtown Bogotá, where campaign caravans and political posters have become a daily feature of city life, voters have expressed exhaustion after months of aggressive rhetoric and constant political confrontation.

With just days remaining before Colombians head to the polls, authorities across the country have increased security measures amid concerns over possible unrest and isolated acts of political violence.

Sunday’s election is widely viewed as one of the most consequential in decades, with the outcome expected to shape Colombia’s political and economic direction long after the campaign slogans and rallies fade from the streets of Bogotá.
