In a new shake-up for the ruling party in the Buenos Aires suburbs, Leila Gianni, councilwoman of La Matanza, announced her resignation from La Libertad Avanza (LLA) on Wednesday, September 2, 2026, with harsh accusations against the party leadership and the direction of Javier Milei's administration.
The news was shared through her official X (formerly Twitter) account, where she posted a message and a video explaining the reasons for her decision. Gianni, who served as Legal Undersecretary of the Ministry of Human Capital under Sandra Pettovello, stepped aside amid growing fractures within the libertarian space in various deliberative councils.
Reasons for the resignation
In her message, Gianni was blunt: “I do not want to be part of a project that, in practice, is leaving many Argentines out and where I feel the people are not being heard”. She also explained that she is leaving a space where she can no longer recognize what she once decided to fight for.
The former official also directly targeted the local leadership, especially national deputy and Buenos Aires party organizer Sebastián Pareja, whom she accused of being “more concerned with power, business, and the scam than with the people”. In that vein, she questioned that “politics cannot be a personal business”.
“Order, yes; forgetting about the people, no. I am not leaving the fight or my convictions. Politics cannot only show up when an election arrives.”
Who is Leila Gianni?
Leila Gianni is a councilwoman of La Matanza, one of the most populous districts in the province of Buenos Aires. Before joining the libertarian space, she had a Kirchnerist militancy, which marked her heterodox profile within LLA. Her time at the Ministry of Human Capital positioned her as one of the voices with access to vulnerable sectors, although her management also generated controversies.
What will she do now?
Gianni will continue to hold her seat as councilwoman, but outside the LLA structure. According to her statements, she plans to keep working in the territory and neighborhoods, and to expose “every injustice and every scam”. Her departure adds to a series of ruptures in LLA blocks in different deliberative councils, evidencing an increasingly tense internal situation within the ruling party.
Political context
Gianni's resignation comes at a time of reorganization for the libertarian space, which seeks to consolidate its structure in the province of Buenos Aires ahead of the next elections. The departure of a figure with a territorial profile like Gianni could be a wake-up call for LLA's leadership, which faces internal criticism for its management style.
So far, neither Sebastián Pareja nor party authorities have officially commented on the resignation. However, reactions in the Buenos Aires political sphere are expected in the coming hours.
