Brazil's Federal Police Investigate Flavio Bolsonaro for Defamation Against Lula

Brazil's Federal Police have launched an investigation into Flavio Bolsonaro, a right-wing presidential candidate, for allegedly issuing defamatory statements against his election rival, President Luiz Inacio Lula da Silva. The probe was ordered by the Supreme Court's Justice Alexandre de Moraes and relates to posts Bolsonaro published in January.

In the posts, Bolsonaro responded to the news of Venezuelan President Nicolas Maduro's abduction by the US with insinuations linking Lula to crimes. He wrote that Lula will be exposed and predicted the collapse of the left-wing alliance known as the Sao Paulo Forum due to scandals including international drug and arms trafficking and money laundering.

Brazil's penal code considers defamation a criminal offence, with prosecutors able to seek heightened penalties for defamation against presidents or heads of state. The Federal Police have 60 days to carry out their initial investigation.

The development comes as Bolsonaro and Lula are in a neck-and-neck race for the presidency ahead of October's general election. A recent poll showed Lula slightly ahead in the first round with 37% of the vote compared to Bolsonaro's 32%, but Bolsonaro polls slightly ahead in a one-on-one contest.

Flavio Bolsonaro, a senator for Rio de Janeiro and the eldest son of former President Jair Bolsonaro, entered the 2026 presidential race with his father's endorsement. He has suggested that seeking his father's freedom would be part of his campaign.
