Overview
- President Javier Milei confirmed Bullrich to head La Libertad Avanza’s Senate caucus, and she convened her first meeting with current and senator‑elect members.
- Reporting counts the future LLA Senate bloc at 20 once Carmen Álvarez Rivero joins, despite Bullrich posting that it will have 21 members.
- PRO deputy Belén Avico announced she is joining LLA in the Chamber of Deputies, with the switch to take formal effect on December 10.
- With Avico’s move, LLA projects 88 own deputies from December, a threshold leaders say helps protect presidential vetoes and steadies votes for key bills.
- The defections sharply shrink PRO’s footprint to roughly 15–16 deputies, while LLA continues recruiting to approach 90 lawmakers of its own and about 115 with allies.
