BERLIN, Aug 27 (Reuters) - German Economy Minister Karl-Theodor zu Guttenberg said on Thursday in a newspaper interview it was "hardly realistic" for General Motors to hold onto its European unit Opel.
Guttenberg also told the Frankfurter Allgemeine Zeitung that Opel bidder Magna still needed to clarify certain aspects of its offer for Opel. (Writing by Sarah Marsh)
