Overview
- Patricia Bullrich confirmed she will head La Libertad Avanza’s Senate bloc from December 10, taking charge of negotiations on the government’s priority agenda.
- The incoming Senate bloc will number about 20 members, reflecting post‑election additions and the decision by PRO senator Carmen Álvarez Rivero to join LLA.
- Deputy Belén Avico left the PRO to join LLA’s bench, adding to the ruling party’s lower‑house tally with a mandate that runs to 2027.
- Five PRO deputies aligned with Bullrich formally moved to LLA’s deputies’ bloc, including Damián Arabia, Silvana Giudici, Patricia Vázquez, Sabrina Ajmechet and Laura Rodríguez Machado.
- LLA projects 88 own deputies from December and is working to reach about 90, with talks continuing as PRO tensions rise under Cristian Ritondo and potential changes involving Silvia Lospennato and Verónica Razzini remain unsettled.
