Overview

• President Javier Milei’s administration formally removed Miguel Blanco as head of SIGEN on July 18 and named Alejandro Fabián Díaz his successor.
• Blanco had held the post since December 2023 with support from ex–Chief of Cabinet Nicolás Posse but faced scrutiny and lost influence following Posse’s 2024 exit.
• Díaz is a certified public accountant with three decades of audit experience, currently overseeing internal controls at Nucleoeléctrica Argentina and finances for the AFA’s Commission Fiscalizadora.
• SIGEN serves as the executive branch’s internal control body, auditing government operations and flagging risks to public assets, a role that has driven investigations into previous administrations.
• The leadership change underscores shifting power alliances within the Milei administration and a move toward technocratic appointments that align with its economic priorities.
