The Brazilian Labour Party (Portuguese: Partido Trabalhista Brasileiro, PTB) is a political party in Brazil founded in 1981 by Ivete Vargas, niece of President Getúlio Vargas. It claims the legacy of the historical PTB, although many historians reject this because the early version of PTB was a center-left party with wide support in the working class. Despite the name suggesting a left-leaning unionist labour party, the PTB joined a coalition led by the centrist to centre-right PSDB.
The party has recently shown strong support for the government of Jair Bolsonaro, presenting policies from a more right-wing angle, in addition to affiliating federal deputy Daniel Silveira, known for making references to AI-5.
In 1981, the military dictatorship that had dismantled the historic PTB decided to revoke its legislation which enforced a two-party state. Ivete Vargas, niece of Getúlio Vargas, became the president of the party.
Soon thereafter, a social-democratic wing of the original PTB, led by Leonel Brizola, founded the Democratic Labour Party (PDT). This all but ensured that the PTB would abandon leftist politics, ultimately embracing centrist or slightly right-leaning politics.
In the 1989, a small dissident faction of moderate social democrats and populists abandoned the PTB and founded the Labour Party of Brazil (PTdoB).
Before the 2010 presidential election, PTB participated in the coalition government of former President Luiz Inácio Lula da Silva, and did not field presidential candidates. 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.
