Brazilian President Luiz Inácio Lula da Silva has won re-election to an unprecedented fourth term after defeating right-wing Senator Flávio Bolsonaro in a closely fought presidential runoff marked by a last-minute extension of voting, allegations of electoral interference and the prospect of a legal challenge to the result.

Brazil’s Superior Electoral Court declared Lula the winner after he secured 51.75 per cent of the vote with 98.76 per cent of ballots counted, while Bolsonaro had 48.25 per cent.
The result completed a dramatic political comeback for the Workers’ Party candidate, who had finished behind Bolsonaro in the first round of voting earlier in October.
In the October 4 first round, Bolsonaro received about 47 per cent of the vote, while Lula secured about 45 per cent, leaving the two men to face each other in the runoff. No candidate in Brazil’s modern democratic history had previously finished second in the first round and gone on to win the second round.
Lula’s victory means he will remain in office for another four years, having previously served two terms beginning in 2003 before returning to the presidency in 2023.
Brazilian law permits a president to serve two consecutive four-year terms but does not impose a lifetime limit on the number of non-consecutive terms a person may serve. The 2026 contest was Lula’s seventh presidential election.
However, the election result immediately faced the possibility of a legal and political battle after Bolsonaro said he would seek the annulment of the election.
Bolsonaro cited a controversial decision by Brazil’s Supreme Court to extend voting nationwide by two hours after the original closing time.
The extension followed complaints about public transport disruptions in several parts of the country and severe weather that affected polling locations.
Both Lula’s and Bolsonaro’s campaigns had requested additional voting time, although they relied on different grounds.
Lula’s campaign complained that interruptions to free public transport in some areas could prevent voters from reaching polling stations, while Bolsonaro’s campaign cited heavy rain, flooding and power outages that affected several voting centres.
Supreme Court Justice Cristiano Zanin subsequently ordered polling to continue nationwide for another two hours, until 7 p.m. Brasília time.
The decision created confusion because it came shortly after the original closing time, when some polling stations had already shut down and begun transmitting results from Brazil’s electronic voting machines.
Brazil’s electronic voting system makes reopening a machine difficult once it has been closed and its results transmitted.
Some voters were consequently unable to cast ballots despite the extension.
At one polling station, five voters who were waiting to vote were told that the electronic machines had already been closed and could not be reopened.
Officials attributed the confusion to conflicting directions from the Electoral Tribunal and the Supreme Court.
The controversy prompted warnings even before the final result that litigation could follow the election.
Brazil analyst Mario Sergio Lima said the extension itself was not necessarily problematic because both campaigns had sought additional time, but said the timing of the decision after some polling stations had already closed complicated the situation.
Bolsonaro’s campaign coordinator, Rogério Marinho, strongly criticised the intervention by the Supreme Court.
“It’s astonishing how much some Supreme Federal Court justices are intervening,” Marinho said.
He described the development as “shameful” and said he hoped that “no judicial coup or procedural trickery succeeds, for the sake of democracy.”
He also expressed fears of what he described as a possible “dictatorship.”
Lula’s campaign, however, argued that the intervention became necessary after alleged disruptions to public transport threatened voters’ ability to reach polling stations.
Campaign coordinator Edinho Silva accused local officials of violating electoral rules by suspending free public transportation.
“Suspending free transportation goes against the law and means direct interference in the electoral process,” Silva said.
Brazil’s Federal Police subsequently began investigating possible electoral crimes connected to disruptions in public transportation.
The investigation covered Bahia, São Paulo, Piauí, Sergipe and Alagoas states, although a formal inquiry had initially been opened only in Sergipe.
Investigators were also interviewing persons involved in providing transport services.
Weather also played a major role in the election-day disruption.
Heavy storms left 163 polling locations without power in Minas Gerais state, with winds reaching speeds of up to 150 kilometres per hour in parts of the state.
About 110,000 customers were said to have remained without electricity in Belo Horizonte as voting continued.
The combination of transport disruptions, heavy rain and the late voting extension made the runoff one of Brazil’s most contentious recent presidential elections.
Despite the controversy, the Superior Electoral Court proceeded with the vote count and eventually declared Lula the winner.
Bolsonaro and his campaign initially remained silent after the declaration and had not conceded defeat when Lula’s victory was announced.
His camp had already criticised the voting extension, and Bolsonaro later indicated that he would seek to have the result annulled because of the Supreme Court’s decision to extend polling by two hours.
The dispute means Lula’s electoral victory could now be followed by legal challenges and negotiations in a political environment already characterised by deep divisions.
Bolsonaro’s political allies also made gains in Congress, while conservative governors retained control of several important states, leaving Lula to govern alongside a legislature containing a strong right-wing bloc.
Speaking to supporters in São Paulo after his victory, Lula said his re-election had safeguarded Brazilian democracy and promised to seek common ground.
He pledged to work with the conservative Congress elected by Brazilians and said he would govern for all of the country’s approximately 215 million people.
Lula said his campaign had convinced voters that participation in the election was essential to protecting democracy.
He also called for greater regulation of digital platforms, arguing that Brazil had resisted foreign interference conducted through online platforms.
“Brazil is no one’s back yard,” Lula told supporters.
His campaign coordinator, Edinho Silva, described the outcome as a “historic victory for democracy” as members of the campaign celebrated the result.
The election was particularly remarkable because Lula had trailed Bolsonaro in the first round and was at several stages behind during the runoff count before eventually taking the lead.
With just over half of the ballots counted, the two candidates were separated by a narrow margin, reflecting the deeply divided nature of the electorate.
Lula later pulled ahead as votes from areas where he enjoyed stronger support were counted.
The 2026 contest also came four years after Lula narrowly defeated Flávio Bolsonaro’s father, Jair Bolsonaro, in the 2022 presidential runoff.
In that election, Lula received 50.9 per cent of the vote against Jair Bolsonaro’s 49.1 per cent, a difference of about 2.1 million votes.
Jair Bolsonaro did not immediately concede defeat after that election.
The latest election took place amid debates over the cost of living, public security, economic policy, environmental protection and the future direction of Latin America’s largest country.
During the final days of campaigning, Lula highlighted congressional approval of a constitutional amendment he backed to reduce Brazil’s working week from six days to five without cutting wages.
He also proposed free public transportation on weekends and debt relief measures for small businesses.
Bolsonaro, on the other hand, campaigned on substantial tax cuts, including proposals to restore pandemic-era tax relief for the events and tourism industries that had been phased out under Lula’s government.
Questions were raised during the campaign over how Bolsonaro would reconcile his proposed tax reductions with his pledge to reduce government spending.
Environmental policy and the rights of Indigenous communities were also major issues.
Under Lula’s administration, deforestation had declined and protections for Indigenous lands had expanded, while Bolsonaro advocated opening some protected areas to mining and farming.
The debate was particularly important in Amazonian regions, where communities are balancing demands for economic development with concerns about environmental protection.
International leaders began congratulating Lula following the declaration of his victory.
Mexican President Claudia Sheinbaum described the result as a victory for democracy and the Brazilian people.
Bolivian President Rodrigo Paz congratulated Lula and said Bolivia and Brazil would continue working together to strengthen relations and create opportunities for their citizens.
Paraguayan President Santiago Peña also congratulated Lula and praised Brazil’s democratic process, while pledging continued cooperation between the neighbouring countries.
United States Senator Bernie Sanders described Lula’s re-election as an “extraordinary” victory and praised his record of supporting Brazilian workers and democracy.
Guatemalan President Bernardo Arévalo congratulated Lula and the Brazilian people, saying the election strengthened democratic institutions.
Uruguayan President Yamandú Orsi said he had personally spoken with Lula to congratulate him on the victory and what he described as a celebration of democracy.
Celebrations broke out among Lula supporters in São Paulo, Rio de Janeiro, Brasília, Porto Alegre and other parts of the country after the result became clear.
Lula now faces the challenge of beginning another four-year term while managing a conservative Congress, political divisions and the possibility of legal proceedings arising from the disputed voting extension.
For Bolsonaro, the immediate focus has shifted from the campaign to challenging the process that produced the result.
The dispute over the Supreme Court’s two-hour extension, allegations of interference with public transport and reports that some polling stations were unable to reopen are therefore expected to remain central to the post-election political and legal debate.
For now, Brazil’s electoral authority has declared Lula the winner, giving the 80-year-old Workers’ Party leader another term in office and completing a comeback unprecedented in the country’s modern presidential elections.
