Lula and Bolsonaro clash in heated first debate ahead of Brazil runoff

Tense opening to a pivotal debate The first televised debate between President Luiz Inácio Lula da Silva, aged almost 81, and Senator Flávio Bolsonaro, 45, took place on Sunday, a week before Brazil’s presidential runoff scheduled for 25 October. According to the Buenos Aires Times, the exchange quickly turned personal, with both candidates repeatedly calling each other liars while raising allegations of corruption and questioning each other's ties to controversial groups.

Main issues and personal attacks The candidates addressed a range of topics that dominate Brazilian voters’ concerns, including the economy, public security, healthcare and Brazil’s relationship with the United States. Bolsonaro, who secured a surprising lead in the first round of voting, focused on the cost of living and insecurity, accusing Lula of reckless spending on social programmes aimed at securing re‑election. Lula countered by asking Bolsonaro to explain any intention to adopt the severe austerity measures implemented by Argentina’s President Javier Milei, which have been linked to higher unemployment and cuts to benefits.

Accusations of corruption and militia links During the debate, Lula described Bolsonaro as a “habitual liar” and a “thug,” refusing to be seen near a “militiaman,” a reference to alleged connections between Bolsonaro and Rio de Janeiro’s paramilitary groups. Bolsonaro, in turn, alluded to Lula’s past legal troubles, reminding viewers that Lula had previously been jailed on corruption charges that were later annulled. He also suggested that keeping a distance from Lula would protect his own finances, implying a risk of theft.

Polls and the road to the runoff Polls released earlier in the week showed Bolsonaro holding a narrow lead, with 51 % of voting intentions compared with 49 % for Lula. The debate did not appear to shift that margin dramatically, but the close figures underscore the election’s competitiveness. Both candidates used the platform to appeal directly to viewers, with Lula urging the audience to verify his statements online.

Closing moments and campaign tone The debate concluded without a clear resolution, reflecting the deep polarization that has characterised the campaign. Bolsonaro’s aggressive pacing and repeated smirks contrasted with Lula’s attempts to maintain composure while repeatedly urging the public to “look it up on Google.” The exchange highlighted the stark differences in style and policy emphasis between the two contenders as Brazil approaches a decisive electoral moment.
