The PDT’s national executive has approved the party’s entry into a federation with Solidariedade, PRD and Avante, while endorsing an effort to bring the PSB into the arrangement. The proposal still requires institutional steps: the parties are expected to ask the Electoral Court to expand the existing Renovação Solidária federation, with its name and statute to be updated if approved.¹

From the PDT’s perspective, the planned alliance is more than an electoral mechanism. Party president Carlos Lupi said the federation would strengthen its members — including lawmakers — in “the defense of democracy and the rights of the Brazilian people,” describing it as an extension of the party’s labour-oriented legacy.¹ The four parties together elected 18 federal deputies: six from PDT, five each from Avante and PRD, and two from Solidariedade.¹

A contrasting account places the negotiations chiefly in the context of the barrier clause, which governs access to party funding and free radio and television advertising. It notes that only the PSB among the prospective participants met the threshold independently, while PDT, Avante and the current federation did not.² The PDT received about 1.6% of valid nationwide votes for federal deputies and elected six members, below both routes to qualifying; Avante recorded 1.59% and elected five deputies in three states.²

That makes the legal and numerical outcome pivotal. The current federation has asked the TSE to count its votes alongside Avante’s, a request supported by the Electoral Prosecutor’s Office, according to the report.² If the broader grouping proceeds, its Chamber representation would rise from seven to 33 deputies and its Senate presence from none to five; its number of elected mayors would increase from 141 to 736.²

Both perspectives therefore converge on federation as the chosen route forward. They differ over emphasis: PDT presents collective political purpose, while the institutional reading underscores a strategy to secure viability under Brazil’s electoral rules.
