Ross Brawn will leave his position as Mercedes team principal at the end of the Formula 1 season.
Brawn and Mercedes have failed to reach an agreement on a role in which he would have been happy to stay at the team, sources close to Mercedes said.
Mercedes will now be run in tandem by their two executive directors, Toto Wolff and Paddy Lowe, along with non-executive chairman Niki Lauda.
Both Mercedes and Brawn refused to comment on the development.
Brawn’s impending departure follows months of talks between Mercedes bosses and the man who masterminded Michael Schumacher’s seven world titles at Benetton and Ferrari.
Brawn also headed Jenson Button’s title-winning 2009 season, entering privately as Brawn GP following Honda’s withdrawal from the sport. Mercedes eventually took over the team for 2010.
