Monisha Kaltenborn has reportedly left Sauber with immediate effect, however, official confirmation has yet to come from the team.
When BMW parted ways with Sauber, Peter Sauber regained control of the team and, in 2010, put Kaltenborn in as CEO and team boss.
Her reign, though, has been anything but a success.
The team’s results have deteriorated leading to a point-less 2014 campaign and just two points scored last season.
As such Sauber have now reportedly parted ways with Kaltenborn.
Seeing news about Monisha and Sauber parting company is starting to break. Expecting confirmation from the team later today.

Next season Sauber, who last year found new owners in Longbow Finance, will swap to Honda power.
Meanwhile, F1 journalist Joe Saward is reporting that Kaltenborn has been “unhappy with the way that Sauber is being overseen by investment manager Pascal Picci, the chairman of the holding company. He is the front man for investors but it is not clear if they have played any significant role in the story.”
