Fabio Luis Lula da Silva, commonly referred to as Lulinha, is the eldest son of the Brazilian president, Luiz Inácio Lula da Silva, and ex-first lady Marisa Letícia. He has been a notable presence in political circles since the start of his father's first term with the Workers' Party. Lulinha is one of five children that President Lula has, and he is frequently mentioned in discussions involving the political and financial affairs of his family, particularly in light of recent controversies surrounding his financial dealings.

On the morning of Thursday, October 26th, 2023, the parliamentary inquiry into the INSS (Brazilian National Social Security Institute) approved the breach of Lulinha's bank secrecy. This action comes amid growing allegations that he may have been involved in financial transactions tied to a key figure in a corruption scandal. Opposition lawmakers have intensified their investigation efforts after accusations surfaced that Lulinha received funds from Antônio Carlos Camilo Antunes, known as "Careca do INSS," raising serious concerns about potential misconduct and corruption at high levels of government.

According to the lead investigator, Deputy Alfredo Gaspar from the Union party in Alagoas, breaking Lulinha's bank secrecy is essential to uncovering the truth from intercepted communications suggesting he acted as an "hidden partner" in a suspicious financial operation involving a R$300,000 payment linked to a company owned by Roberta Luchsinger. The outcome of this investigation could have significant implications for both Lulinha and the integrity of the current government under his father's leadership, as it draws attention to the intertwining of personal and political financial issues in Brazil.
