President Luiz Inácio Lula da Silva won re-election on Sunday after gaining ground across nearly 97 percent of Brazilian municipalities in the decisive runoff.
Official data from the Superior Electoral Court showed that the incumbent expanded his advantage or narrowed the gap against challenger Flávio Bolsonaro in 96.7 percent of cities compared to the opening round of voting on October 25.
With 100 percent of electronic voting machines counted, Lula secured 51.79 percent of the valid vote, representing 64,256,232 ballots. Bolsonaro, a federal senator representing Rio de Janeiro for the Liberal Party, took 48.21 percent, or 59,826,041 votes.
Following the final tally, Bolsonaro announced that he did not recognise the outcome and said he would petition electoral authorities to annul the vote.
Municipal vote shifts across Brazil
According to figures released by the Superior Electoral Court, known in Brazil as the TSE, Lula improved his standing in 5,389 municipalities, representing 96.7 percent of the country's local administrative districts. He lost ground in only 182 cities, or 3.3 percent.
The incumbent widened his margin in 2,630 cities where he had already finished ahead during the first round. He also cut into Bolsonaro's lead in another 2,546 municipalities where the challenger had led the opening stage of the contest.
Lula also overturned first-round defeats in 213 municipalities, including two state capitals. He reversed the result in Rio de Janeiro, the country's second largest metropolis, and in Macapá, the capital of the northern state of Amapá.
Key reversals in state capitals
In the city of Rio de Janeiro, Lula received 1,524,517 votes, or 43.91 percent, in the first round, trailing Bolsonaro, who secured 1,662,354 votes, or 47.88 percent. In Sunday's runoff, Lula surged to 1,898,391 votes, capturing 51.54 percent, while Bolsonaro recorded 1,785,198 votes, or 48.46 percent.
The turnaround in Rio de Janeiro represented a major victory for Lula, as Bolsonaro serves in the National Congress as a senator representing the state. Brazilian political terminology uses the term fluminense to denote people and politicians from Rio de Janeiro state.
A similar reversal occurred in Macapá, situated along the Amazon River in northern Brazil. Lula rose from 114,179 votes and 43.30 percent in round one to 125,479 votes and 50.99 percent in the runoff. Bolsonaro slipped from 124,378 votes and 47.16 percent to 120,593 votes and 49.01 percent.
Turnout growth between election rounds
Lula added 10.3 million votes between the first and second rounds, lifting his national tally from 53.8 million to 64.2 million. That increase was nearly three times larger than the growth achieved by Bolsonaro, who picked up 3.7 million additional votes, rising from 56.1 million to 59.8 million.
Under Brazilian electoral law, a presidential candidate must secure more than 50 percent of all valid votes in the initial vote to win outright. Because neither contender passed that threshold in early October, the two highest-polling candidates advanced to Sunday's head-to-head runoff.
Lula's victory makes him the first Brazilian president to achieve re-election since Dilma Rousseff won a second term in 2014. Rousseff, like Lula, represented the Workers' Party, the dominant left-of-centre political party in South America's largest country.
Electoral authority and legal challenges
Lula, whose full name is Luiz Inácio Lula da Silva, previously served two terms in office from 2003 through 2010 before returning to the presidency. Flávio Bolsonaro contested the race as the candidate of the conservative Liberal Party.
Brazil conducts all voting through electronic ballot boxes, known locally as urnas eletrônicas, which are monitored and tabulated by the Superior Electoral Court. The federal electoral tribunal serves as the supreme judicial authority on national balloting, responsible for certifying vote counts and resolving legal challenges.
Following the conclusion of the vote count, Bolsonaro stated that he did not recognise the result and said he would petition electoral authorities to annul the election.
