The Revolutionary Workers' Party Trotskyist–Posadist (Spanish: Partido Obrero Revolucionario Trotskista Posadista, POR-TP) was a small Trotskyist political party in Bolivia formed in 1963. It was established by a dissident group which broke away from the Revolutionary Workers' Party of Bolivia.[1] It was led by workers' leader Carlos Flores Bedregal.[2]
In 1978 and 1979, the POR-TP took part in an electoral coalition, the Democratic and Popular Union, backing Hernán Siles Zuazo.[3]
For the 1980 elections, the POR-TP was the component of the Democratic Revolutionary Front-New Alternative, with the OID's leader Luis Adolfo Siles Salinas as the coalition's presidential candidate.[4]
In 1985, it took part in an electoral coalition, the United Left, backing Isaac Sandóval Rodríguez.[5]
