Brazil's presidential election will be decided in a second-round run-off on 25 October after right-wing candidate Flávio Bolsonaro won the first round but fell short of the outright majority needed to claim victory. With 98.81% of ballots counted, the 45-year-old senator secured 47.24% of the vote, while incumbent left-wing President Luiz Inácio Lula da Silva trailed with 44.91%. Because neither candidate crossed the 50% threshold, the contest now moves to a decisive head-to-head vote later this month.
The result represents a significant upset. Lula had maintained a narrow but consistent lead throughout the campaign, and most pre-election polling suggested the veteran leftist would enter the run-off with momentum. Instead, Flávio Bolsonaro confounded expectations, consolidating right-wing support more effectively than analysts had anticipated. His stronger-than-expected showing has shifted the political dynamic, with the second round now widely viewed as his to lose.
Flávio Bolsonaro is the eldest son of former president Jair Bolsonaro, who is currently serving a 27-year prison sentence for masterminding a failed coup attempt following his defeat in the previous election. Barred from seeking re-election even before his conviction, the elder Bolsonaro endorsed his son to carry the family's political banner. The family's influence remains potent: Jair Bolsonaro's wife, Michelle, was elected to the Senate on the same day, underscoring the enduring grip of the Bolsonaro brand on Brazil's conservative movement.
The political rivalry between Lula and the Bolsonaro family has once again polarised the world's fourth-largest democracy. The two camps represent fundamentally opposing visions for Brazil, and the campaign has been fought over issues of national sovereignty, public security, economic management and corruption. For many voters, the choice is not merely between two candidates but between two starkly different directions for the country.
Lula, now 80, is seeking an unprecedented fourth term in office. First elected in 2002 and re-elected in 2006, he returned to power in 2022 after a non-consecutive term, defeating Jair Bolsonaro by less than two percentage points — the narrowest presidential result in Brazil's history. After that contest, Bolsonaro's supporters stormed and vandalised government buildings on 8 January 2023 in an attempt to overturn the result, an event that continues to shadow Brazilian politics.
Speaking after casting his ballot, Lula framed the election as a referendum on democracy itself, warning that voters faced a choice between democratic governance and "barbarism." Flávio Bolsonaro, meanwhile, struck a liberating tone, stating that he wanted to "free the Brazilian people" from what he characterises as excessive state control and political persecution.
The candidates draw support from sharply different segments of Brazilian society. Lula performs best in the poorer northeast, among low-income voters, Catholics and women. Flávio Bolsonaro's base lies in the wealthier south, among evangelical Christians and higher-income voters. These regional and demographic divides have defined Brazilian elections for years, and the run-off will test whether either candidate can broaden their coalition.
One of the most consequential promises of Flávio Bolsonaro's campaign is a pledge to grant amnesty to his imprisoned father and to supporters convicted for their role in the 8 January riots. Such a move would be deeply controversial, potentially triggering legal challenges and mass protests. Critics argue it would undermine the rule of law, while supporters view it as a necessary act of national reconciliation.
The election has also been shaped by questions of foreign influence. During the campaign, Lula made "sovereignty" a central theme, at times accusing the United States of attempting to interfere in Brazil's electoral process. He has promised to increase defence spending as part of a broader push to assert Brazilian autonomy on the world stage. On Sunday, the president of Brazil's supreme electoral court stated that no evidence of international interference had been detected.
Tensions with Washington have been a recurring subplot. Earlier this year, Flávio Bolsonaro successfully lobbied the United States to designate Brazil's two largest criminal gangs as terrorist organisations. In July, Brazil refused visas for two US State Department officials whom it accused of trying to cast doubt on the integrity of Brazil's electoral system — allegations Washington dismissed as "baseless." The dispute followed reports that Flávio Bolsonaro had told foreign diplomats that Brazil's voting machines share the same origin as Venezuela's, a claim that is false.
Last year, US President Donald Trump cited the coup trial of Jair Bolsonaro as justification for imposing tariffs on Brazil and sanctioning senior Brazilian officials and judges. A victory for Flávio Bolsonaro would likely see Brazil align more closely with Washington, including joining the US-led "Shield of Americas" coalition against narco-trafficking. However, he has also pledged to maintain an "economically pragmatic" relationship with China, which has overtaken the United States as Brazil's largest trading partner and remains a vital buyer of Brazilian soy and beef.
Corruption emerged as a dominant campaign issue following a scandal involving jailed banker Daniel Vorcaro, who orchestrated one of Brazil's largest financial frauds and became entangled with senior figures across the political spectrum. Flávio Bolsonaro acknowledged asking Vorcaro to bankroll a biopic about his father after audio recordings emerged in which he could be heard requesting 134 million reais — approximately $25.9 million or £19.5 million. Lula was also indirectly affected, after police suggested Vorcaro had contacted Supreme Court judge Alexandre de Moraes to seek help avoiding arrest. Moraes has denied any wrongdoing.
The outcome of the run-off carries significance far beyond Brazil's borders. Much of Latin America has shifted to the right in recent years, with newly elected presidents aligned with the Trump administration. Brazil, as the region's largest country and economy, is seen as a pivotal prize. A Bolsonaro victory would cement that rightward realignment; a Lula win would preserve a major left-wing counterweight in the hemisphere.
With three weeks remaining until the decisive vote, both campaigns will now focus on courting supporters of the candidates eliminated in the first round. The majority of those knocked out were right-wing alternatives, a factor that appears to favour Flávio Bolsonaro. Lula, by contrast, must mobilise his base and persuade centrist voters that he remains the safer choice. The 25 October ballot will determine not only who governs Brazil but also the country's democratic trajectory and its place in a rapidly changing global order.
