Silva, until now a vice-presidential candidate for the Brazilian Socialist Party, accepted its nomination to top the ticket after candidate Eduardo Campos, a former governor and rising political star, was killed in a plane crash last week.

Silva pledged to build a more prosperous Brazil and slammed the performance of incumbent President Dilma Rousseff, who has overseen four years of lackluster growth and high inflation in a previously booming economy.

"We know that our country needs investments and they will come when there is a new government that has credibility among investors," she said at a news conference.

Silva reaffirmed her commitment to fiscal responsibility, inflation targeting and a floating exchange rate, the so-called "tripod" of economic policies that gave Brazil stability after a period of rampant inflation and erratic growth in the 1990s.

Viewed as an outsider with no links to traditional elites, Silva is a former environment minister whose ironclad environmental and religious beliefs prompt critics to call her inflexible but supporters to praise her as Brazil's most principled politician.
