Word in the paddock suggests that long time team principle Monisha Kaltenborn has resigned from her position within the Sauber Formula One team. Kaltenborn, 46, was the Sauber team CEO and the first female team principal in F1 following her promotion through the ranks on the back of the departure of BMW factory support in 2010. She is widely regarded as a respected and sensible member of the Formula One fraternity and is seen by many as one of the key players in securing the teams future following financial struggles in recent years. With many wondering what the future holds for the team following the recent takeover by Swiss investment group Longbow Finance at the end of last season, Kaltenborn was retained in her previous role to head up the team as it looks to regroup and fight its way back into a midfield position within the Formula One grid. However after a disastrous start to the current campaign that has seen the Swiss team fail to register a regular assault on a points paying position, it is understood that Sauber and Kaltenborn have agreed to part ways from each other with immediate effect. Although yet to be officially confirmed by the squad, Sky Sports understand that the termination of the relationship between the two comes in the wake of a clash of opinions on the way forward for Sauber in Formula One. "There is significant speculation that what caused her to leave the team is that she wanted equal treatment between the two drivers Pascal Wehrlein and Marcus Ericsson," Sky Sports Craig Slater reported from Baku. "Whereby the team's owners wanted to give preferential treatment to Ericsson, the Swede, who is closely linked to the group that bought the team." Sauber are expected to head into the upcoming Azerbaijan Grand Prix this weekend without an official Team Principle following the departure of Kaltenborn and team namesake Peter Sauber, who left the outfit as part of the purchase deal by Longbow last year.
