The directors of the Brazilian Socialist Party, or PSB, Wednesday voted to name former senator and leading environmentalist Marina Silva as the party’s candidate for Brazil’s upcoming presidential elections, the party said. Silva will take the place on the ticket of former Pernambuco state governor Eduardo Campos, who was killed last week in a plane crash. Ms. Silva will be joined on the ticket by PSB congressman Beto Albuquerque as vice-presidential candidate. Upon acceptance of the nomination, Ms. Silva said she planned to continue with a party platformed outlined previously by Mr. Campos. “We have a commitment with the responsibilities already assumed, built shoulder to shoulder, night and day, under the leadership of Eduardo,” she said, and repeated his campaign slogan: “We’re not going to give up on Brazil.” Ms. Silva will face incumbent Brazilian President Dilma Rousseff of the Workers’s Party and frontrunning opposition challenger Aecio Neves of the Brazilian Social Democratic Party in the elections, scheduled for October 5. Ms. Silva ran as a presidential candidate for the Green Party in the country’s 2010 elections, taking nearly 20% of the vote. According to a recent poll by Brazil’s Datafolha opinion research institute, Ms Silva currently has backing from about 21% of Brazilian voters, compared to 36% for Ms. Rousseff and 20% for Mr. Neves. As part of a pact to bring Ms. Silva onto the PSB ticket, the party agreed to allow the candidate to avoid state-level alliances previously made by Mr. Campos with some of the party members of Mr. Neves’ PSDB party, including São Paulo and Rio Grande do Sul state government candidates Geraldo Alckmin and Beto Richa. Regarding economic policy, Ms. Silva said she was in agreement with an economic stability program supported by Mr. Campos. “Since 2010 I have defended inflation targets, a floating exchange rate and fiscal responsibility,” she said. On the more controversial matter of central bank autonomy, Ms. Silva said the subject was under discussion with the parties in her campaign coalition, but believed it could get support. “Central bank autonomy has never been a problem for us,” she said.
