BERLIN (Reuters) - IG Metall union said on Sunday there is no reason to undermine Volkswagen (>> Volkswagen AG) Chairman Ferdinand Piech after the row over the carmaker's leadership.

Berthold Huber, prominent member of the union and also deputy chairman of VW's supervisory board, said it's important to have two strong personalities at the top of Europe's largest automotive group.

"We are determined with (Chairman) Piech and (Chief Executive Martin) Winterkorn to continue the successful path of VW also in future," Huber said in a statement.

Senior supervisory board members were ready to demand Piech's resignation at a meeting on April 16 had he not agreed to a statement backing Winterkorn, Frankfurter Allgemeine Sonntagszeitung reported on Saturday.
