Overview
- The PSB’s national leadership voted on Thursday to authorize its executive to open negotiations with the PDT over a federation, a step that starts formal talks but does not yet confirm membership.
- The PDT previously approved on November 6 its intention to join the federation already formed by Solidariedade, PRD and Avante, creating a five‑party proposal if the PSB signs on.
- Key PSB figures at the meeting included Vice‑President Geraldo Alckmin, party president João Campos and deputy Tabata Amaral, who backed talks to deepen cooperation with the PDT.
- If the PSB joins the bloc the five parties would total about 33 deputies and five senators, which would increase their weight in the Chamber and Senate and give them pooled access to party funds and campaign time.
- Federations under Brazilian law require member parties to act as a single entity for at least four years, so the next steps are internal ratification by each party and formal registration before the alliance can shape congressional strategy or back specific leadership reconductions.
