Volkswagen sees positive Q2 results : CFO

"The chances of a positive decision have declined objectively because of the negative vote by KfW, but of course we continue to look at every application seriously," Guttenberg said in an advance copy of an interview to be published on Sunday by the Bild am Sonntag newspaper.

Focus magazine reported that the Qatar Investment Authority could buy more shares in Porsche than previously thought.

Qatar has been discussing the possible size of a stake with Porsche and is expected to reveal the outcome in two to three weeks, according to media reports.

However, Poetsch declined to comment on whether VW was involved in negotiations between Porsche and Qatar. Likewise he refused to comment on another magazine report that Daimler (DAIGn.DE) was interested in taking a stake in Porsche.
