Senior members of German Chancellor Angela Merkel's cabinet sent conflicting signals at the weekend over whether the government should provide aid to Opel, suggesting divisions within her government on the issue, Reuters reported. Economy Minister Rainer Bruederle said in an interview with the Bild am Sonntag newspaper that he expected Opel's U.S. parent General Motors to shoulder the full burden of a restructuring of Opel.

On cancelling the sale last week, GM said it would still seek state aid.
