Overview
- At least five PRO deputies tied to Patricia Bullrich announced or were reported to be moving to La Libertad Avanza, led publicly by Damián Arabia’s declaration on social media.
- Reports name Silvana Giudici, Sabrina Ajmechet, Patricia Vázquez and Laura Rodríguez Machado among those shifting, with some outlets also listing Alejandro Bongiovanni and putting the total at seven.
- Ámbito projects LLA’s caucus rising toward 88 seats after the December 10 renewal, a level that would surpass one third of the Chamber and strengthen the government’s leverage.
- The PRO bench would shrink as a result, with Ámbito estimating a drop from 24 to 19 deputies, while party figures scramble to court new congressional allies.
- Although some formal block changes may be recorded after December 10, outlets say the realignment is effectively in place, reflecting a deeper rupture with Mauricio Macri that sources close to Arabia link to his 2027 positioning.
