FE Brasil, the federation uniting the PT, PCdoB, and PV, holds a commanding position as the likely second-largest bancada in the Chamber of Deputies following the October 4 election. Early tallies and projections show the PL securing the most seats overall, consistent with strong performance by right-leaning candidates aligned with former President Jair Bolsonaro, while the FE Brasil grouping trails but maintains a clear lead over other federations and parties such as União Brasil, PP, and PSD. Partial results from most states reinforce this ordering, with seat allocations still pending final certification in remaining jurisdictions. Uncertainties around exact margins in high-delegate states or minor adjustments during final counting represent the primary scenarios that could alter the ranking, though current evidence points to limited volatility in the top two positions.
