Arroyo, who served as Defense Minister for just 21 days, takes over as Cabinet chief following Denisse Miralles’ abrupt departure ahead of confidence vote

LIMA, Peru — March 18, 2026 — Peru’s interim President, José María Balcázar, has appointed retired Army Major General Luis Enrique Arroyo as the country’s new Prime Minister following the unexpected resignation of Denisse Miralles just three weeks into her tenure, plunging the transitional government into a fresh political crisis .

Arroyo, who had been serving as Defense Minister under Miralles since February 24, was sworn in during a ceremony at the Government Palace in Lima on Tuesday, March 17 . His appointment came just hours after Miralles submitted her resignation letter to President Balcázar, triggering the automatic resignation of all 18 other Cabinet ministers under Peruvian law .

Sudden Resignation Shakes Transitional Government

Miralles, 49, who previously served as Economy Minister under Balcázar’s predecessor José Jerí, did not specify a reason for her departure in her letter to the president. She wrote simply: “In response to the request that… you were so kind to make for me… I hereby tender my effective resignation” .

The resignation came one day before a scheduled confidence vote in Congress, where Miralles needed a majority of legislators to confirm her appointment . Local press reports indicated that Balcázar’s leftist picks were unlikely to be approved by the legislature, which is controlled by the right-wing opposition .

Peruvian law requires Cabinet leaders appointed by the president to pass a vote of confidence within their first month in office. Failure to do so results in the resignation of the entire Cabinet .

President Balcázar’s office thanked Miralles for her service in a statement published on social media, saying: “The Presidency of the Republic of Peru thanks Mrs. Denisse Miralles for the services given to the nation” .

Arroyo’s Military Background and Experience

The newly appointed Prime Minister brings extensive military and disaster management experience to the role. Arroyo, a retired major general of the Peruvian Army from the 1981 class “Heroes of Tacna and Arica,” had been serving as Defense Minister for only 21 days before his elevation to the presidency of the Council of Ministers .

Prior to his Cabinet position, Arroyo served as chief of the National Civil Defense Institute (Indeci) from November 5, 2025, to February 24, leading actions focused on disaster risk management and emergency response at the national level .

During his military career spanning several decades, Arroyo commanded the Third Army Division in Arequipa and the Fifth Division in Iquitos. He also served in the Valley of the Apurimac, Ene, and Mantaro Rivers (VRAEM), a region known for coca cultivation and remnants of Shining Path insurgent activity .

In the academic sphere, Arroyo served as director of the Peruvian Army Superior War College (ESGE), an institution dedicated to the training and professional development of senior officers. According to the Ministry of Defense, “this experience aligns with the technical profile required to lead a portfolio responsible for the formulation and implementation of policies on national security and defense” .

Cabinet Reshuffle and Transition Period

Following Arroyo’s appointment, President Balcázar moved quickly to fill other key positions. The interim president named new ministers for Defense, Interior, and Economy portfolios, though specific appointees were still being finalized as of Tuesday afternoon .

Rodolfo Acuña, a deputy in Peru’s finance ministry, was appointed as the new Economy Minister .

“The transitional government has a mission to lead a phase of stability, focused on ensuring full transparency of the electoral process,” President Balcázar’s office said in a statement following the Cabinet changes .

Political Context and Elections

Balcázar, 83, assumed the presidency in late February after his predecessor, José Jerí, was impeached on corruption allegations . He is Peru’s eighth head of state in the past 10 years, reflecting the profound political instability that has gripped the Andean nation .

The interim president will govern until July 28, when he is scheduled to hand over power to the winner of the April 12 general elections . More than two dozen candidates are participating in the presidential race. If no candidate secures more than 50 percent of the votes, a runoff will be held in June between the top two contenders .

Despite the revolving door of presidents, Peru’s economy has remained relatively stable over the past decade, with successive governments adhering to orthodox economic policies that include modest fiscal spending and encouragement of international investment in mining and infrastructure .

Miralles, in her final public appearance as Prime Minister on Monday, had emphasized the government’s commitment to stability and democratic transition. “Peru does not need more political instability; it needs results and responsibility,” she stated. “It is time to demonstrate that democracy is built on trust and joint work” .

The former prime minister had outlined four lines of work for the remaining 134 days of the transitional government, including strengthening energy security following a recent natural gas crisis, implementing citizen security plans, and ensuring clean and transparent elections .

Arroyo now assumes responsibility for advancing these objectives while managing a Cabinet that must quickly rebuild confidence with a Congress that had been poised to reject his predecessor.
