Dilma Rouseff has become the first woman to be elected as president of Brazil. A former Marxist guerrilla who was imprisoned and tortured during Brazil’s long dictatorship, Rousseff said her first priority would be the eradication of poverty in the country. Her election is seen as a major victor for Brazil’s popular incumbent president, Lula Da Silva. Rousseff served as da Silva’s chief of staff. She has never before held elected office.
