Ariadna Montiel Reyes, the former Secretary of Welfare, was elected as the national leader of Morena on May 3, 2026 [1].

This leadership transition occurs as the party seeks to eliminate internal corruption and organize its strategy for the upcoming 2027 elections [2].

Montiel assumed her role during the VIII Extraordinary National Congress [3], which took place at the World Trade Center in Mexico City [1]. During the meeting of the National Council, she said she reaffirmed her support for Claudia Sheinbaum [2].

Montiel used the platform to warn against corruption within the party ranks. She said she outlined a strategic direction for Morena that focuses on maintaining party discipline, and integrity as the organization prepares for the 2027 election cycle [2].

Her rise to leadership follows a period of collaboration with other party figures. Montiel and Clara Brugada previously trained 100 mayors on implementing governments with a humanist vision [4]. This experience in local governance and training is expected to inform her national leadership style.

The transition marks a shift from the previous leadership under Luisa Alcalde [5]. Party allies said Montiel's appointment is a step toward a historic day in 2027 [6].
