SANTIAGO DE COMPOSTELA German Finance Minister Christian Lindner said at the informal EU finance ministers meeting on Friday that a decision is not expected this week on who will become European Investment Bank (EIB) president.

"There are several well-qualified candidates, for example our host today, Nadia Calvino," Lindner said before the meeting of euro zone finance ministers.

Lindner said the German government hasn't made a decision yet on which candidate to back, "but we have a clear picture of how the EIB should develop."

Lindner said the bank should keep its AAA rating: "Sound banking is essential for us."

But he also noted that the bank has some room for improvements. "The EIB can be more agile," Lindner said.

"For us today and the next weeks, it is essential to have an exchange on the use of the EIB, and after that, we will make decisions about the person," Lindner said.
