The Brazilian Socialist Party's campaign manager quit on Thursday hours after environmentalist Marina Silva became its presidential candidate, causing a rift in her team just 45 days before the election, Reuters reported. Carlos Siqueira, a close aide to the party's late leader Eduardo Campos, who was killed in a plane crash last week, said he could not work with the new candidate and someone else should be chosen. Silva, a popular anti-establishment figure whose candidacy has shaken up Brazil's Oct. 5 presidential election, said Siqueira's departure was a "misunderstanding." Party officials said another campaign manager would be named by the end of the day. Silva joined the PSB less than a year ago after failing to register her own party in time for this year's general election. The lesser-known Campos picked her as his running mate to draw her large number of supporters. His death on Aug. 13 thrust Silva into a presidential race that she could win, according to an opinion poll published on Monday that showed her just ahead of President Dilma Rousseff in a second-round runoff between the two. -- SPA 22:58 LOCAL TIME 19:58 GMT تغريد
