Brazil's first presidential debate of the 2026 election takes place Sunday evening, pitting incumbent President Luiz Inácio Lula da Silva of the Workers' Party (PT) against Senator Flávio Bolsonaro of the Liberal Party (PL). The two-hour event, hosted by TV Bandeirantes in São Paulo, begins at 8 p.m. local time and will be broadcast across a pool of networks including TV Gazeta, TV Cultura, Jovem Pan, and the newspaper O Estado de S. Paulo.
Speaking to journalists before the debate, Flávio Bolsonaro said the PT's campaign has been built on lies and vowed to use the confrontation to expose them. "The base of the PT campaign were lies," he said. "It will be very satisfying to rub some truths in his face." He also said he would have preferred to face Lula in the first round and called the debate an opportunity to "bring the truth to the Brazilian population."
The debate format, agreed upon by both campaigns and the broadcaster, consists of three blocks. In the first, anchors Eduardo Oinegue and Adriana Araújo put one question to each candidate, followed by 30 minutes of open exchange. The second and third blocks each feature anchor questions plus direct candidate-to-candidate questioning, with the final block closing with concluding statements from each contender. A draw determined podium positions: Flávio Bolsonaro on the left, Lula on the right.
The encounter marks the first head-to-head meeting between the two leading candidates in a race that has been framed as a referendum on Lula's third term and the legacy of the Bolsonaro era. Flávio Bolsonaro, son of former president Jair Bolsonaro, is running as the standard-bearer for the right-wing coalition after his father was barred from office until 2030 over abuse of power allegations.
Lula, 81, seeks a fourth presidential term after winning the 2022 runoff against Jair Bolsonaro by the narrowest margin in Brazil's modern democratic history. His administration has focused on social spending, environmental enforcement in the Amazon, and re-engagement with multilateral forums, while facing criticism over fiscal discipline and congressional governance.
Polls ahead of the debate show a tight race, with most surveys placing the two candidates within the margin of error. The debate is widely seen as a pivotal moment that could shift undecided voters in the final stretch before the October 25 first round.
