Brazil Votes in High-Stakes Election as Lula Faces Flávio Bolsonaro in Battle Shaped by His Father's Legacy

Brazilians cast their ballots on Sunday in a general election whose presidential contest is dominated by two figures whose names carry enormous political weight in the country. Voting concluded at 5pm local time (8pm GMT), and the country's electronic voting system was expected to produce results within hours.

The incumbent, Luíz Inácio Lula da Silva, is seeking to extend his hold on power, while his most serious challenger is Flávio Bolsonaro, a right-wing senator carrying forward the movement founded by his father, former president Jair Bolsonaro. Eleven other candidates are also on the presidential ballot, but they have struggled to break into double digits in the polls.

The election is taking place against an extraordinary backdrop. The last presidential race, four years ago, ended with Lula narrowly defeating Jair Bolsonaro. Rather than conceding, the former president's allies and supporters mounted a campaign that culminated in thousands of them storming Brazil's Congress, and Jair Bolsonaro was subsequently convicted of plotting a coup. That conviction and its consequences continue to overshadow the nation's politics.

Jair Bolsonaro, the right-wing former army captain who governed from 2019 to 2023, is not on the ballot this time. The 71-year-old is barred from holding public office and is serving a 27-year sentence for his role in the coup plot that followed his 2022 defeat. Health problems have kept him under house arrest rather than in prison, but restrictions bar him from posting on social media or making public statements.

Even in confinement, his presence is felt throughout the campaign. At the event where Flávio Bolsonaro officially launched his candidacy, supporters were shown an AI-generated avatar in which Jair Bolsonaro appeared to endorse his son. When the Supreme Court questioned the use of the deepfake, lawyers for the elder Bolsonaro suggested he had not authorised it, but few observers doubt that Flávio enjoys his father's genuine backing.

The polls indicate a tight contest. BBC Brasil's tracker shows both Lula and Flávio Bolsonaro hovering around the 40% mark, with the incumbent holding a slight advantage. None of the other eleven candidates has exceeded 4% support. To win outright, a candidate must secure more than half of all valid votes, and failure to do so would send the top two finishers into a run-off scheduled for 25 October.

Most analysts expect a second round, given the even split between the front-runners. However, a relatively large pool of undecided voters means an outright first-round victory cannot be completely discounted. At the end of September, BBC Brasil's poll aggregator found that 9% of voters were still undecided, intended to spoil their ballots, planned to cast blank ballots, or did not intend to vote at all.

Voting is compulsory in Brazil for literate citizens aged between 18 and 70, and 16 and 17-year-olds are entitled to take part. Those who fail to cast a ballot without justification face a fine. Nearly 160 million people are eligible to vote in this election, a vast electorate that makes accuracy in polling difficult. Surveys typically sample only a few thousand people, which helps explain why results can diverge significantly from the final tallies.

Lula, now 80, is running for the left-wing Workers' Party and has already served as president three times. He held office for two consecutive terms between January 2003 and December 2010, a period in which he earned widespread praise for lifting millions of Brazilians out of poverty through a cash-transfer scheme known as Bolsa Família. The former metalworker left office with approval ratings above 80%, a level of popularity rarely seen in Brazilian politics.

His later years were clouded by corruption scandals that engulfed his party. Lula himself was imprisoned for more than 18 months between 2018 and 2019 after being convicted of corruption and money laundering, charges he has consistently rejected as politically motivated. Those convictions were later annulled, clearing the way for his return to the presidency.

Flávio Bolsonaro, by contrast, is running to preserve and extend his family's political project in his father's enforced absence. The campaign has leaned heavily on nostalgia for the elder Bolsonaro's presidency and on the loyalty of a committed conservative base. Yet the younger Bolsonaro must also contend with the legal cloud hanging over his family name and with voters who may credit the coup plot conviction as proof that the movement he represents poses a danger to democratic institutions.

The result will carry consequences well beyond Brazil's borders. Lula has positioned himself as a defender of national sovereignty and a voice for developing countries on the world stage, a theme he emphasised in his recent address to the United Nations General Assembly. A Flávio Bolsonaro victory would mark a sharp pivot back toward the combative, right-wing posture that defined his father's time in office and strained Brazil's relations with major partners.

Whatever the outcome, the 2026 election will test the resilience of Brazil's democratic system just four years after it came under violent assault. The swift delivery of results by the country's electronic voting system will be watched closely, and any dispute over the count could reopen wounds that have not yet healed. For now, the nation waits for the tally that will determine who leads Latin America's largest democracy for the years ahead.
