Brazil Heads to Runoff: Bolsonaro Jr. Edges Out Lula in First Round
Brazil's presidential election will be decided in a runoff on October 25 after right-wing Senator Flávio Bolsonaro narrowly finished ahead of incumbent President Luiz Inácio Lula da Silva in the first round of voting on October 4. Neither candidate secured the majority required for an outright victory, setting the stage for a decisive contest between two deeply polarised political camps.
According to Brazil's Superior Electoral Court (TSE), Flávio Bolsonaro, the son of former President Jair Bolsonaro, won 47.03 per cent of the valid vote, while Lula secured 45.16 per cent. With 99.99 per cent of ballots counted, Bolsonaro received 56,104,268 votes against Lula's 53,876,617. The TSE recorded 125,272,513 valid votes, along with 2,300,781 blank votes (1.84 per cent) and 3,674,149 null votes (2.93 per cent).
The result has drawn global attention, not only because Brazil is Latin America's largest economy, but because it places the country's political future at the centre of a broader ideological contest between left and right. For Lula, 80, the outcome is a setback to his hopes of avoiding a second round. For Flávio Bolsonaro, 45, it is a strong first-round performance that gives the Bolsonaro movement a chance to return to the presidency.
How Brazil's presidential election system works
Brazil uses a two-round system for presidential elections. A candidate must secure more than 50 per cent of valid votes to win outright. Blank and null votes are excluded from this calculation. If no candidate reaches the threshold, the two leading candidates advance to a second round, which becomes a direct two-way contest.
The first round on October 4 also involved elections for governors, senators, and federal and state legislators. Voters cast ballots for six positions: federal deputy, state or district deputy, two senators, governor and vice-governor, and president and vice-president. This means the election determines both the executive leadership and a significant portion of the legislative balance in the National Congress.
The ability of either candidate to govern effectively after January will depend heavily on the composition of Congress and their capacity to build legislative alliances. Winning the presidency does not guarantee full control of the legislature.
Why Flávio Bolsonaro finished ahead of Lula
Flávio Bolsonaro's first-round performance exceeded expectations. Polling had underestimated the strength of his support, and his campaign benefited from voter dissatisfaction over the cost of living, corruption and public security, according to Reuters.
The result also reflects the resilience of the political movement associated with Jair Bolsonaro, who is serving a prison sentence after being convicted in connection with an attempted coup. The former president remains a polarising figure, but his influence over the national electorate has not diminished.
Flávio's campaign has been both a personal presidential bid and an effort to sustain the broader Bolsonaro coalition. A victory on October 25 would transform that political legacy into a new presidency.
Key issues in the runoff campaign
Economy and cost of living
Brazil has made progress on unemployment and inequality under Lula, but concerns remain about public debt, fiscal policy and economic growth. Brazil's public debt was reported at 82.9 per cent of GDP in August. Lula has defended the existing fiscal framework while arguing for continued social spending. Flávio Bolsonaro has positioned himself as the candidate for a more business-friendly economic direction with tighter fiscal discipline.
Public security
Brazil has long struggled with organised crime, drug trafficking and violent crime. The Bolsonaro camp is likely to advocate a tougher approach to law enforcement, while Lula's camp is expected to stress government programmes and institutional approaches to public security.
Corruption
Both political camps face vulnerabilities on corruption. Lula's career has been shaped by allegations involving the Workers' Party, although his convictions were annulled by Brazil's Supreme Court in 2021 on jurisdictional grounds. The Bolsonaro family has also faced allegations and investigations.
The Amazon and environmental policy
Brazil's environmental policy has global repercussions. Lula has targeted zero net deforestation by 2030, while Flávio Bolsonaro has pledged to end 'illegal' deforestation by 2029. The issue affects Brazil's relations with the United States, European countries and trading partners, as well as international climate negotiations. The Amazon also carries enormous economic importance as Brazil seeks to expand agriculture and infrastructure while facing pressure to protect its forests.
What role could the United States play?
Flávio Bolsonaro is politically aligned with US President Donald Trump. A Bolsonaro victory would likely strengthen ties between Brazil's conservative right and the Trump administration, extending a wider regional trend of right-wing victories among Trump-aligned leaders.
Lula's foreign policy has been different. His government has sought strategic autonomy and maintained relationships with China, the United States, Europe and the wider Global South.
How does Brazil vote?
Brazil is known for its electronic voting system. Voting takes place through electronic voting machines, and the TSE oversees the national electoral process. Results are transmitted and totalled rapidly after polling stations close. Voting ended at 5 pm Brasília time on October 4.
The TSE provides mechanisms for citizens to inspect individual polling-station results. Voters can use the Results system to examine totals and access polling-station Boletins de Urna, or voting bulletins. The Boletim na Mão feature allows voters to scan the QR code printed on a polling-station bulletin and compare recorded results with the totals published by the electoral authority.
What happens between now and October 25?
Brazil now enters the most important phase of the election. Eliminated candidates are no longer competing, but their voters become crucial. Both Flávio Bolsonaro and Lula will seek to attract those voters through new alliances, endorsements and policy promises.
Flávio has already secured support from political allies in several states, while Lula has governors and gubernatorial candidates aligned with his campaign. The second round could therefore become as much about coalition-building as about the two candidates themselves.
What is at stake for Brazil?
Brazil is Latin America's largest economy and one of the world's most important agricultural and commodities producers. Its president has enormous influence over environmental policy, trade, foreign affairs and relations with major powers. Brazil is also a major player in the Brics grouping and an influential voice among developing countries.
A Bolsonaro victory would represent a major ideological shift after Lula's return to power. A Lula victory would give the veteran left-wing leader another term and extend the Workers' Party's influence over the national government. The new presidential term is scheduled to begin in January 2027.
How many people were eligible to vote?
Brazil had 158,745,463 registered voters eligible to participate in the 2026 election, according to the TSE. That represents an increase of 2,291,452 eligible voters, or 1.46 per cent, compared with the 2022 election. Brazilian citizens living abroad could vote for president and vice-president, while voters inside Brazil participated in the wider set of contests.
The scale of the electorate makes Brazil's presidential election one of the largest democratic exercises in the world this year.
