Argentine President Javier Milei Targets Brazilian Leader Luiz Inácio Lula da Silva Ahead of Runoff Election
Argentine President Javier Milei launched a fresh verbal attack on his Brazilian counterpart, Luiz Inácio Lula da Silva, casting doubt on the transparency of Brazil’s upcoming presidential runoff election. With the second-round vote scheduled for October 25, Milei used social media to label the Brazilian president a “thieving lefty” and suggested the election could be manipulated. Without any mediating bilateral issues or reasons of state, Javier Milei called Luiz Inacio Lula Da Silva a “thieving lefty” while seeking to sow suspicions about the transparency of the neighboring country’s runoff.
The bilateral friction intensified as Milei threw his political backing behind candidate Flávio Bolsonaro, the right-wing candidate and son of convicted former president Jair Bolsonaro, whom the libertarian supports to end Lula da Silva’s reelection bid. The Argentine leader posted a series of attacks on the platform X, formerly Twitter, targeting Lula days before voters return to the polls.
Social Media Attacks and Allegations of Election Fraud
Javier Milei accused Luiz Inácio Lula da Silva of running a dirty campaign and insinuated that the incumbent administration might attempt to rig the vote, echoing an accusation that Jair Bolsonaro made against Lula in 2022. I hope his latest dirty campaign trick doesn’t include stealing the election,” Milei posted, adding the insult “thieving lefty.

The Argentine president based part of his online tirade on a distorted interpretation of an interview Lula gave to SBT News. During the broadcast, Lula discussed the division of household labor, noting that working women cannot work six days a week and rest one because that day they have to clean their homes, as an example that women are mostly in charge of care tasks, shortly after Parliament sanctioned the reduction of the workweek from 48 to 40 hours. Milei seized on the comments to brand Lula a “machinist progressive” while accusing him of hypocrisy regarding misogyny. During his address, the Argentine President also referred to Lula with various qualifiers such as “Don Lula”, “The lefty”, “Thief”, and “The prisoner”, and questioned the Brazilian government over the detention of Jair Bolsonaro, stating that “socialist garbage” had to be stopped.
Escalating Diplomatic Tensions and Electoral Stakes in Brazil
The diplomatic rupture between Buenos Aires and Brasília has deepened significantly since Milei took office, with bilateral ties currently reduced to the level of chargés d’affaires and ambassadors awaiting instructions to return to their posts. The tensions stem partly from a visit by Milei to São Paulo on July 25, where he participated in a campaign event for Flávio Bolsonaro at the Pacaembú stadium alongside São Paulo Governor Tarcísio de Freitas, prompting Brazil to recall its ambassador to consultations after Milei called Lula a “thief” and “corrupt” in a television interview.

In the first round of voting on October 4, Flávio Bolsonaro secured 47.15 percent of the vote, while Lula reached 45.02 percent. Because neither candidate cleared the 50 percent threshold, they advanced to the October 25 runoff. Milei congratulated Flávio Bolsonaro, the son of former president Jair Bolsonaro, hailing him as a dear friend and describing Lula as a communist. On October 7, the Argentine leader had already published an Instagram story with the phrase “LULA THIEF” over an image of the Brazilian head of state featuring a statement from Cato Institute Vice President for International Studies Ian Vásquez attributing opposition to Lula to corruption. Meanwhile, Lula’s campaign team used Milei’s chainsaw policy to urge voters not to support Bolsonaro, publishing posts claiming nearly half of Argentines are in misery.
