BRASILIA (Reuters) - The political party that launched environmentalist Marina Silva's unsuccessful Brazilian presidential bid will back pro-business candidate Aecio Neves in the Oct. 26 runoff vote against leftist incumbent President Dilma Rousseff, a party spokeswoman said on Wednesday.
The decision by the Brazilian Socialist Party increases the likelihood that the bulk of Silva's 22 million votes would go to Neves and increase his chances of defeating Rousseff.
The party's executive board voted overwhelmingly to support Neves, with 21 in favor. Only one board member voted to support Rousseff and seven voted to remain neutral.
Silva, who came third in Sunday's first-round vote, is expected to endorse Neves on Thursday after meeting with the parties that backed her bid.
