SUZUKA, Japan - Ross Brawn on Wednesday added his own denial to reports that he has decided to leave Mercedes at the end of the 2013 season.Chairman Niki Lauda has already played down the reports, saying he is in negotiations with 58-year-old team boss Brawn, whom he would like to keep at Brackley, but the big rumour is that Brawn has decided to leave because his obvious successor at Mercedes is Paddy Lowe.Brawn is being linked with a move to 2015 McLaren engine supplier Honda but the Japanese automaker's motor racing boss Yasuhisa Arai denied that on Wednesday.'IT'S A SURPRISE'Arai told British broadcaster Sky: "I've never heard of that and it is a surprise. I don't think it will happen."Brawn added his own denial on Wednesday when he told Germany's Auto Motor und Sport: "The situation is the same as it has been for the last few weeks. I am still talking to Niki about my role in the team."He was even more strident when asked about McLaren and Honda."I have not spoken a word with Honda or McLaren," said Brawn. "My decision can wait until the end of the season. I'm not somebody who makes a decision overnight. Should I look elsewhere, I would think about it very hard and consider the options carefully. It takes time."Auto Motor und Sport said Brawn, a keen salmon and trout fisherman, had not even ruled out taking a sabbatical. "It would not be the first time," said Brawn.
