Javier Milei swore in Diego Santilli, the new Chief of Cabinet | La Derecha Diario en Inglés

President Javier Milei swears in Diego Santilli as the new Chief of Cabinet this Tuesday, after having officially announced his appointment last Sunday. Santilli, who until now served as Minister of the Interior, replaces Manuel Adorni. Santilli's arrival at the head of the ministers has a strong internal consensus, backed by the trust of Karina Milei and his good rapport with advisor Santiago Caputo.

Under the watchful eye of his wife and children, the newly appointed official sealed his commitment to the administration by swearing on “God, the Fatherland, and the Holy Gospels”. The event reflected a climate of camaraderie and continuity, sealed with a hug between Javier Milei and the outgoing official, Manuel Adorni, who led an orderly transition after leaving office.

In a gesture of clear political purging, the Government decided to exclude the most recalcitrant faces of Kirchnerism from the invitations: Axel Kicillof (Buenos Aires), Gildo Insfrán (Formosa), and Ricardo Quintela (La Rioja) were not part of the gathering.

The list of governors who chose the path of dialogue and sensibility included Jorge Macri (CABA), Martín Llaryora (Córdoba), Alfredo Cornejo (Mendoza), Rogelio Frigerio (Entre Ríos), Raúl Jalil (Catamarca), Leandro Zdero (Chaco), Juan Pablo Valdez (Corrientes), Carlos Sadir (Jujuy), Rolo Figueroa (Neuquén), Alberto Weretilneck (Río Negro), Marcelo Orrego (San Juan), Claudio Vidal (Santa Cruz), Osvaldo Jaldo (Tucumán), and Gustavo Sáenz (Salta). This federal consensus positions Santilli as a significant player in parliamentary articulation and the management of strategic agreements with the provinces.

Internally, the appointment of Diego Santilli enjoys total backing. Unlike his predecessors, he assumes with the absolute internal consensus granted by the trust of Karina Milei —Secretary General of the Presidency— and the excellent rapport with advisor Santiago Caputo, who identified him as the ideal man for the second half of the term. Caputo himself celebrated the appointment on social media, consolidating a team where political trust and operational effectiveness are the fundamental pillars.

The president, Javier Milei, and the new chief of cabinet ministers, Diego Santilli.

Santilli's background is that of a proven and meritocratic manager. Born on April 6, 1967, he is a public accountant graduated from UBA with excellent training abroad: marketing at Berkeley, specialization in futures markets in Washington, and a postgraduate degree from the Paris School of Management.

His curriculum includes a successful tenure as Deputy Head of the Buenos Aires Government, where he won in 2019 with 55.9% of the votes, and a historic electoral comeback in the province of Buenos Aires in October 2025. In that effort, the alliance La Libertad Avanza-PRO achieved 41.5% of the votes, adding 881,417 votes in just 49 days under his leadership.

For this new stage, Santilli has designed a highly efficient structure. He will be joined by Ignacio Devitt —pushed by Karina Milei— as Deputy Chief of Executive Cabinet, and Gustavo Coria as Deputy Chief of the Interior, replicating a model that seeks to maintain political and administrative control with a firm hand. With this team, the Government is preparing to deepen the second-generation reforms and the 2026 Budget, tasks in which Santilli has already demonstrated concrete results during his eight months at the head of the Interior portfolio.

Starting this Wednesday, the new Chief of Cabinet will begin an intensive agenda of media and ministerial meetings, coordinating actions with spokesperson Adrián Ravier and Press Secretary Fabián Fernández. The arrival of Diego Santilli is not just a simple change of names; it is the consolidation of a strategic leadership that, under the guidance of Javier Milei, promises to oil the state machinery so that the changes that Argentines voted for become irreversible.
