According to court documents released on Friday by Reuters, Brazil’s Supreme Court has launched a corruption and money laundering investigation into Senator Flávio Bolsonaro, the eldest son of former president Jair Bolsonaro and a leading challenger to incumbent President Luiz Inácio Lula da Silva in the upcoming October presidential election.
Investigation into Banco Master and Film Financing
Supreme Court Justice André Mendonça authorized the investigation on July 22 at the request of federal police, as reported by Reuters. The probe forms part of a broader inquiry into the collapse of Banco Master. The film is scheduled for release in Brazil this October.
Allegations and Political Stakes
Federal police are probing potential crimes of money laundering, illegal foreign exchange transactions, and corruption, according to court documents cited by Reuters. Daniel Vorcaro was arrested in March on similar allegations. Flávio Bolsonaro acknowledged asking the former bank director for financial backing for the Jim Caviezel film project, but he denied any wrongdoing. Meanwhile, Supreme Court President Edson Fachin ordered the release of thousands of pages of documents related to the broader Banco Master scandal on Thursday, though certain details concerning Flávio Bolsonaro remain classified.
Polling and Electoral Impact
The investigation arrives during a tense electoral cycle. Recent polling shows a tight race between President Lula and Flávio Bolsonaro ahead of the October 4 first round, where Lula holds 38 percent support against Bolsonaro’s 33 percent, followed by Augusto Cury at 8 percent and Ronaldo Caiado at 4 percent. A potential second-round runoff projects Lula at 46 percent and Bolsonaro at 44 percent, shifting slightly from an August ratio of 47 to 43 percent, per data. President Lula supports full transparency, stating, “Everything must be investigated, and everything must be made public, regardless of who it hurts,” according to the documents.
