Switzerland has given Brazil access to the bank accounts of Brazilian politicians and executives at Petrobras that could shed light on allegations of corruption at the state oil group, the Swiss Office of the Attorney General (OAG) said.
Switzerland's highest court, the Swiss Federal Court, rejected a last appeal by some of the people involved after a lower court had allowed the transfer of documents.
A Brazilian investigation into Petrobras has uncovered systemic corruption at multiple companies and at the highest levels of government. Allegations of bribes and political kickbacks in the case have triggered protests across Brazil.
Last year, the OAG widened the Swiss part of the investigation to include Latin America's largest engineering company, Odebrecht SA, and its subsidiaries.
