Oct.7 (GMM) Mercedes on Monday denied reports Ross Brawn has decided to leave the team at the end of the season.
"I don't know where this story is coming from," Mercedes team chairman Niki Lauda told SID news agency.
"Nothing has changed."
Lauda did, however, admit that negotiations are currently taking place, but a decision will "definitely not" be made within the current season.
He said Mercedes wants to keep Brawn on board, "but of course it's his decision".
