Brazil Petrobras scandal: Workers' Party treasurer Vaccari steps down

Mr Vaccari is charged over an alleged scheme in which the party received dirty money from inflated deals between oil executives and construction firms.Party president Rui Falcao said he still had confidence in Mr Vaccari.He is the closest ally of President Dilma Rousseff to have been arrested in the broadening scandal.The arrest places further pressure on the president, who has faced street protests, impeachment calls and plummeting opinion ratings since her re-election four months ago.Ms Rousseff served as the head of Petrobras for much of the period when the corruption took place, but she has not been implicated in the scandal.More than 40 politicians, including the heads of both houses of congress, are being investigated over the affair.
