Since Rousseff was sworn in January as the country's first woman president, seven of her 38 ministers have quit, including six who were embroiled in allegations of graft and embezzlement. But analysts say South America's largest economy and a key emerging power remains stable. "There is no sense of crisis as the ministers lose their jobs, but their parties retain the ministries. Rousseff has been able to deal with the scandals without destroying her coalition," said Carlos Lopes, head of Analisis, a political think tank. Since June, she has lost one minister per month, but it does not appear to have affected her popularity as the economy is going well and each resignation is seen as part of her housecleaning efforts, several analysts told AFP. The general perception is "the president acts more quickly against corrupt politicians than her predecessors, that she is less tolerant of irregularities," said Rafael Cortes, an analyst at the Tendencias think tank. The latest minister to go was Carlos Lupi, who after months of what he called "political and personal persecution by the media," resigned as labor minister on Sunday. Rousseff's office announced that Lupi, who has been dogged by corruption charges in the media since early November, would be temporarily replaced by Paulo Roberto dos Santos Pinto, a senior ministry official. "The biggest political armor protecting the president is the economy and as long as Brazilians do not feel the impact of the crisis, all will be under control. In addition, Rousseff is governing with a very weak opposition that does not provide an alternative for now," noted Andre Pereira, a political scientist and sociologist at the CAC research center in Brasilia. In July, Rousseff was compelled to launch an anti-corruption drive after several key members of her government were accused of graft including her chief of staff Antonio Palocci, who resigned a month earlier. Agriculture minister Wagner Rossi, transport minister Alfredo Nascimento and tourism minister Pedro Novais were all forced to step down amid allegations of graft and embezzlement. Communist lawmaker Aldo Rebelo was named Brazil's new sports minister in October, tasked with organizing the 2014 World Cup after his predecessor Orlando Silva resigned amid corruption allegations. And Nelson Jobim resigned as defense minister in August, not over corruption charges, but after he criticized the government to reporters. Brazil, Latin America's leading economy, has taken steps to ensure that the eurozone debt risis and economic woes in the United States do not hinder its growth, capitalizing on its strong domestic market and booming exports of commodities mainly to China. The departure of seven of Rousseff's 38 ministers effectively brought forward a cabinet reshuffle she had planned to make next month to mark her first year in office after taking over from popular president Luiz Inacio Lula da Silva, also a member of the leftist Worker's Party (PT). "The resignations are unlikely to break the (ruling) coalition or to lead to paralysis in Congress. Dilma will continue to maintain political stability and will be able to focus on the economy," Cortes said. Corruption has only recently begun to be seen as an issue in Brazil's political culture, the expert noted. "It's an issue that is currently barely on the radar of the voters, who for many years did not make a distinction between the government's good and bad practices," Cortes said.
