Brazil’s presidential candidates Luiz Inácio Lula da Silva and Flávio Bolsonaro have completed their final campaign appearances before voters go to the polls in a closely contested election. The first-round vote will determine whether either candidate can secure the presidency outright or whether Brazil heads to a run-off later in October.
The election has wider regional significance because it could shape Brazil’s approach to organised crime, public finances, relations with the United States and its role in Latin America. While Lula is defending his record as the incumbent, Flávio Bolsonaro is seeking to return his family’s political movement to the presidency.
Final rallies held in São Paulo and Rio de Janeiro
Lula held his closing rally in São Paulo, Brazil’s largest city, where supporters used slogans focused on national sovereignty and his return to office. The veteran left-wing politician is seeking a fourth and final presidential term.
Flávio Bolsonaro, a senator and the son of former president Jair Bolsonaro, concluded his campaign with events linked to São Paulo and Rio de Janeiro. His campaign has focused heavily on public security, tougher action against organised crime and fiscal austerity.
The two candidates have presented sharply different visions for Brazil:
- Lula: a left-wing platform centred on sovereignty, social policy and opposition to perceived external interference.
- Flávio Bolsonaro: a right-wing programme focused on security, spending restraint and criticism of the incumbent government’s economic record.
A divided contest with international implications
The campaign has unfolded against a backdrop of strained relations between Brazil and the United States. Lula has criticised US tariffs imposed on Brazilian goods and has repeatedly warned against outside interference in Brazil’s electoral process.
The dispute has added an international dimension to the vote. Washington has also taken steps involving major Brazilian drug-trafficking organisations, while the Trump administration’s relationship with Jair Bolsonaro has become a recurring issue in the campaign.
Flávio Bolsonaro has used imagery associated with Donald Trump at some rallies, including large US flags and inflatable figures. Trump has not formally endorsed the senator, but has said he is following the Brazilian election closely.
Scandals and personal attacks dominate the campaign
Policy debates have often been overshadowed by allegations, investigations and highly personal exchanges. Flávio Bolsonaro has faced scrutiny over an investigation connected to financing for a film about his father. The matter is linked to jailed banker Daniel Vorcaro, who is also being investigated in a major financial case involving figures connected to Brazil’s political and judicial establishment.
The allegations remain part of an ongoing investigation and do not amount to a final judicial finding. Both campaigns have used the controversy, along with opponents’ public statements and perceived mistakes, in online political advertising.
Social media has played a central role in the contest. Supporters of both candidates have circulated rapidly produced videos, manipulated material and AI-generated images, making it increasingly difficult for voters to distinguish campaign messaging from unverified claims.
What happens after the first round?
Twelve candidates are standing in the presidential race, but polling cited in the report indicates that Lula and Flávio Bolsonaro are the only contenders viewed as having a realistic chance of reaching the presidency. Neither is expected to win more than half of the vote in the first round.
If no candidate secures an outright majority, the leading two candidates will proceed to a second round scheduled for 25 October. The final result could therefore depend on how supporters of the other candidates realign after Sunday’s vote.
Voters will also elect members of Brazil’s legislature, governors and some senators. Those contests will influence the next president’s ability to pass legislation and implement promises on security, taxation, public spending and social policy.
Key points for voters and observers
- The first-round presidential election is scheduled for 4 October.
- Lula and Flávio Bolsonaro are the leading candidates in the reported polling.
- A second round is expected if neither candidate wins outright.
- The run-off is scheduled for 25 October.
- Legislative and gubernatorial elections will take place alongside the presidential vote.
Why the result matters beyond Brazil
Brazil is Latin America’s largest country and one of the region’s most influential economies. A change in government could affect its diplomatic posture, trade relations, security policy and approach to cooperation with other countries in the region.
A Flávio Bolsonaro victory would place Brazil alongside several Latin American countries that have recently elected right-leaning governments. A Lula victory would preserve the current administration’s emphasis on sovereignty and resistance to pressure from Washington.
The election may also affect debates over the cost of living, public security and the balance between fiscal restraint and government spending. However, the president’s ability to act will depend partly on the composition of Congress and the results of state-level elections.
What to watch next
The immediate focus will be the official first-round count and whether either candidate reaches the threshold required to avoid a run-off. If the contest proceeds to a second round, both campaigns are likely to seek support from voters who backed the remaining candidates.
For international observers, the key issues will include the conduct of the vote, the response of the candidates to the result and the direction of Brazil’s foreign and economic policy after the final outcome is confirmed.
The central takeaway from this election is that Brazil’s choice extends beyond a contest between two political families. It will determine the country’s domestic priorities and its position in a region facing competing pressures from the United States, economic uncertainty and political polarisation.
