By Global Leaders Insights Team | Jun 29, 2026
Argentine President Javier Milei has named Interior Minister Diego Santilli as the country's new chief of cabinet, replacing Manuel Adorni, who resigned amid a corruption investigation. The change comes at a crucial time for Milei's government as it works to keep its economic reforms on track while facing increasing political pressure.
The appointment, announced by the president, will take effect on Tuesday. Santilli is a well-known political figure with years of experience in public office and is expected to play a key role in improving coordination within the government and building support for its legislative agenda.
Santilli has held several senior positions throughout his political career, including deputy chief of the City of Buenos Aires, security minister for the capital, national deputy, and senator. His experience in both government administration and lawmaking is expected to help the Milei administration strengthen its ties with provincial leaders and lawmakers.

After accepting the new role, Santilli said he would fully support the government's reform agenda and work to ensure its policies continue moving forward. His appointment also reflects Milei's decision to rely on experienced leaders from outside his own La Libertad Avanza party to help manage key government responsibilities.
Many political observers believe Santilli's leadership could provide greater stability at a time when the government is trying to maintain public confidence while implementing major economic changes.
Cabinet Reshuffle Follows Corruption Investigation
Santilli's appointment comes after Manuel Adorni stepped down as cabinet chief following allegations related to his personal finances. Prosecutors are investigating claims of possible illicit enrichment and examining whether his declared income matched his lifestyle and spending.
The investigation focuses on several expensive family trips, including a first-class holiday to Aruba and travel to Uruguay on a private jet. Critics questioned whether these expenses were consistent with Adorni's reported earnings while serving in government.
Adorni has strongly denied any wrongdoing. He has said that his assets were accumulated before entering public office and that all of his personal travel was paid for with private funds. He has also pledged to cooperate fully with the investigation and clear his name.
The controversy has added to the political challenges facing President Milei's administration. While the government continues to push ahead with measures to reduce public spending, encourage foreign investment, and strengthen the Argentine economy, it is also facing growing scrutiny over government transparency and accountability.
