Overview
- Javier Milei held the first meeting of his revamped team, installing Manuel Adorni as chief of cabinet and Diego Santilli as interior minister, with Pablo Quirno taking over foreign affairs and Mariano Cúneo Libarona staying on at Justice.
 - Santilli said his focus is the Presupuesto 2026, labor modernization, a tax reform and a new Penal Code, signaling an extraordinary‑session push after Dec. 10 even as a committee dictamen was scheduled for Nov. 4.
 - La Libertad Avanza is set to preside over an 87‑member bloc from Dec. 10, after five PRO deputies—Damián Arabia, Sabrina Ajmechet, Silvana Giudici, Patricia Vásquez and Laura Rodríguez Machado—defected, with two more PRO electees and Santilli’s replacement adding to the count.
 - Controlling a third of the Chamber of Deputies strengthens the government’s hand to sustain vetoes and complicate impeachment efforts, reshaping negotiations in the new Congress.
 - Provincial leaders offered a mixed response as Corrientes’ Gustavo Valdés and Chubut’s Nacho Torres congratulated Santilli, others reported no contact and some lamented Guillermo Francos’s exit, while market commentary praised the new lineup but pressed for concrete legislative wins.
