[13] Since the conservative wave in the 2010s, the party had shown strong support for the government of Jair Bolsonaro,[14] presenting policies from a more right-wing angle, in addition to affiliating federal deputy Daniel Silveira, known for making references to AI-5.

[15] After the 2022 Brazilian general elections, PTB failed to break through the electoral threshold, thus cutting access to party subsidies and free political advertisement.

After Vargas' suicide in 1954, PTB's main figures became Leonel Brizola and João Goulart, who was elected vice-president in 1960 — becoming president after the resignation of Jânio Quadros — until his deposition after the 1964 coup d'état.

[17] In 1979, the military dictatorship that had dismantled the historical PTB decided to revoke its legislation which enforced a two-party state.

In the 1989, a small dissident faction of moderate social democrats and populists abandoned the PTB and founded the Labour Party of Brazil (PTdoB), which was renamed to Avante in 2017.

The party, however, did not support Lula's candidate to succeed him, Dilma Rousseff (herself a former historical PTB/PDT member), as it embarked on PSDB José Serra's failed campaign for president.
