The President announced that the current Minister of the Interior will take office on Tuesday at 4 PM. Santilli arrives at the position with legislative experience, executive management, and a connection with governors
President Javier Milei confirmed this Sunday the appointment of Diego Santilli as the new Chief of Cabinet of Ministers, following the departure of Manuel Adorni. The current Minister of the Interior will take office next Tuesday at 16:00, as the president himself informed through his social media.
“Here with the new Chief of Cabinet of Ministers @diegosantilli and the Sec. Gen. of the Presidency @KarinaMileiOk outlining the foundations for an orderly transition of the position. The oath will be on Tuesday at 16:00 hs,” Milei wrote on his X account, alongside a photo of the three in the Olivos residence.
Santilli arrived at Olivos past 19:15, where he was received by the President and the Secretary General of the Presidency, Karina Milei, to advance in formalizing his new functions within the national government.
His arrival at the Chief of Cabinet comes after his time at the Ministry of the Interior, an area from which he was responsible for the political relationship with governors and the coordination with various legislative sectors.
The “Colo” had strengthened his ties with the ruling party during the alliance between PRO and La Libertad Avanza for the national legislative elections of 2025 in the province of Buenos Aires. In that campaign, Santilli ended up leading the list after the resignation of José Luis Espert, conducting a historic campaign that defeated Kirchnerism in the province of Buenos Aires.

With the ruling party's victory in the Buenos Aires territory, one of the most complex districts for any non-Peronist government, Milei confirmed Santilli as Minister of the Interior, with the aim of strengthening dialogue with provincial leaders and organizing the political relationship of the Executive with Congress.
Santilli has an extensive career in public service. He was a city legislator, Minister of Environment and Public Space of Buenos Aires City, national senator, deputy mayor of Buenos Aires City, and Minister of Justice and Security during the administration of Horacio Rodríguez Larreta. In 2021, he was elected national deputy for the province of Buenos Aires.
A public accountant from the University of Buenos Aires, he also completed training studies abroad related to public administration, marketing, and futures markets. His profile combines executive experience, legislative background, and territorial knowledge, three attributes that will be central for a Chief of Cabinet that must coordinate daily management and sustain the government's reform agenda.
