# Christophe Mirmand sworn in as Monaco's new minister of state
On 2025-07-21, Christophe Mirmand officially took office as Monaco's minister of state in a ceremony at the Prince's Palace, according to L'Observateur de Monaco. The swearing-in marked the formal start of his mandate and confirmed the end of Isabelle Berro-Amadeï's stint as acting head of government.
The report says the ceremony began at 11:30 a.m. and was attended by Prince Albert II, Princess Charlene, the secretary of state, government members, and the prince's cabinet. Mirmand was named by sovereign ordinance on July 2, and the swearing-in was the final constitutional step before he assumed the role.
The article describes Mirmand as a senior French civil servant with a long career in central and territorial administration. It says he studied at the École nationale d'administration, holds a degree in history, a master's in international and European law and a DESS in financial management. It also notes that he served as secretary general of the French interior ministry and later as prefect in several regions, including Alpes-Maritimes, Corsica and Brittany.
The report gives a short biography that also places him in the Mediterranean policy environment that Monaco cares about. It says he became prefect of the Provence-Alpes-Côte d'Azur region in 2020 and later served as chief of staff to French overseas territories minister Manuel Valls. That experience, the article suggests, made him familiar with the administrative and regional issues that cross between France and Monaco.
The swearing-in itself was presented as solemn and formal. According to the source, the prince read the oath before Mirmand raised his right hand and said, "Je le jure." The secretary of state then read the official record. Those are procedural details, but they help show that the transition was handled through Monaco's formal institutions rather than through a political break.
The article does not describe any policy announcements from Mirmand on his first day. It also does not say how long Berro-Amadeï will remain visible in the government or what immediate priorities the new minister will face. Even so, the change matters because the minister of state is Monaco's top government official and a central bridge between the prince and the administration.
In a small state with highly structured institutions, personnel changes at the top carry more weight than they might elsewhere. This report shows Monaco completing a planned leadership transition with the usual ceremonial precision, while bringing in a figure with long experience in French state administration.
For a routine news account, the essential points are simple: Mirmand was appointed by ordinance, sworn in at the palace on July 21 and installed as the new minister of state in the presence of the princely family and government officials. That is the event the source documents, and it marks a new phase in Monaco's executive leadership.
