"In every country of Latin America the actions of the [US] intelligence are different, but in all of them they seek to create instability," Siba Machado of the Workers’ Party (PT) said.
Machado pointed out the alleged links between the CIA, movements calling for a motion of no-confidence against President Dilma Rousseff and the Brazilian Social Democracy Party (PSDB), the main opposition party in the country.
"I am convinced that the CIA has long been acting in secret in Brazil. Above all opposition movements, of the PSDB or Aecio Neves [PSDB head] are CIA operations," Machado said.
Rousseff assumed office for a second term on January 1. Local media reported in the summer that Neves was seeking to impeach the president over her alleged involvement in the corruption scandal involving Brazil’s giant Petrobras oil company.
Senior Petrobras officials allegedly took bribes from major construction and engineering companies in Brazil in exchange for inflated contracts. Some opposition figures believe that Rousseff, who headed Petrobras for seven years from 2003-2010, was aware of such practices.
Earlier this month, Rousseff accused the country's political opposition of seeking to oust her government by plotting coups.
The US Central Intelligence Agency is against Brazil developing its nuclear program, and is responsible for the failure of the project that would have enabled the country to obtain a nuclear submarine by 2025, a Brazilian lawmaker said.
In 2008, Brazil and France agreed to a defense technology transfer to assist the South American country in building its first ever nuclear submarine by 2025, under the Program of Submarine Development (PROSUB). Federal police in Brazil have launched an investigation into some of the subcontracts of this submarine project in connection to an ongoing corruption probe of Brazil’s Petrobras energy company.
"I have no doubt that the CIA has no interest in allowing Brazil to develop its own nuclear program. This is why PROSUB would find many problems in advancing," Siba Machado of the Workers’ Party (PT) said.
According to local media reports, citing the Brazilian Navy, the country’s nuclear submarines are currently being designed, with the plans expected to be finished by the end of 2015.
Top Petrobras officials are accused of conspiring with construction companies to inflate contracts, as well as of bribing politicians.
The engineering company Odebrecht has been implicated in this inflated contracts scheme and has also worked as a subcontractor on PROSUB submarine project.
The corruption scandal, dubbed the largest in Brazilian history, has seen charges pressed against the country’s speaker of the lower house and a former president.
