Ross Brawn is expected to sever his ties with the Mercedes F1 team at the end of the current season, several months later than originally expected.
The Briton, whose eponymous team morphed into the Brackley-based works outfit following a buy-in inspired by Jenson Button's 2009 world championship campaign, had been thought likely to leave as soon as Paddy Lowe joined from McLaren, but a change of heart by Mercedes allowed for a 'soft transition' and gave Brawn the opportunity to discuss future roles within the organisation.
Even as recently as last weekend's Indian Grand Prix, the former Benetton and Ferrari head man was insisting that talks were continuing, but the BBC
now believes that negotiations over the level of authority he would hold have reached an impasse
, with Brawn expected to hand over the reins to Lowe after next month's Brazilian finale.
“There is a transition going on,” Brawn conceded on Friday, “We're just determining what will be the best timing for that. I want the team to be in the best possible place for next year, so I think when the time is right we'll let everyone know what we're doing. But, at the present time, that's all I want to say on the matter.”
The 58-year old's exit is set leave Lowe and fellow executive director Toto Wolff in joint charge ahead of the 2014 campaign, with the former managing technical and sporting matters, and the latter business aspects.
Where Brawn goes from here, should he indeed leave Brackley, remain uncertain, despite rumours linking him to both Williams and, thanks to its impending Honda connection, McLaren. Brawn, of course, inherited the former Honda F1 operation, transforming it spectacularly into the title-winning team bearing his own name.
Mercedes, which currently occupies second place in the constructors' championship with three races remaining, refused to comment on the speculation, saying that it would 'make a statement when there was something to announce'.
