Petrobras picks new chief exec

Petrobras plans to name engineer Maria das Graças Foster as chief executive, promoting a respected technocrat from the Brazilian oil giant's ranks to turn around its lacklustre performance in recent years. Foster, the firm’s natural gas and power director, would be the first woman to run Petrobras if the board approves her promotion on 9 February. A native of a poor Rio de Janeiro suburb, Foster started at the company as an intern in 1978.
