Peru’s interim President, Jose Maria Balcazar, on Tuesday (March 18, 2026) appointed General Luis Enrique Arroyo as Prime Minister, after Denisse Miralles unexpectedly resigned Tuesday (March 18, 2026) — three weeks into her tenure — plunging the newly formed government into crisis.

Mr. Arroyo served as Defence Minister under Ms. Miralles, whose departure came the day before a confidence vote by Congress, resulting in the 18 other Peruvian Cabinet members appointed by President Jose Maria Balcazar also having to step down.
