WOLFSBURG, Germany, Jan 23 (Reuters) - Volkswagen will have a difficult time selling the 600,000 new Golf cars the German carmaker aims to build this year, the head of the group's works council said on Friday.
"It's very ambitious. It will not be easy to reach," Klaus Volkert, who sits on the supervisory board at Europe's biggest carmaker, told Reuters in an interview.
VW stock fell two percent to 40.86 euros by 1326 GMT, underperforming peers on the DJ European autos index and the German blue-chip DAX index .
The Golf is VW's best-selling model and is key to its aim of lifting profits this year, but investors have been concerned in recent weeks that the new model -- which went on sale late last year -- is not selling as quickly as hoped.
Analysts at Merrill Lynch cut their rating on VW to "sell" earlier this week, saying that many German dealers were reportedly complaining of weak demand for the new car.
Volkert also said he did not expect the so-called "VW law" -- a controversial rule that caps shareholder voting rights at 20 percent -- to remain in place forever, but that it was nonetheless worth fighting for.
"I'm not so pigheaded as to believe the law will stay for a hundred years," Volkert said, but added that it had value in protecting VW from hostile takeover bids.
The European Commission, which has already warned that the law breaches EU rules, has said it will decide next week on whether to take further legal action against Germany.
