Sauber have confirmed they have parted company with team principal Monisha Kaltenborn with immediate effect. Here is their statement in full.
"Longbow Finance SA regrets to announce that, by mutual consent and due to diverging views of the future of the company, Monisha Kaltenborn will leave her positions with the Sauber Group effective immediately.
"We thank her for many years of strong leadership, great passion for the Sauber F1 Team and wish her the very best for the future.
"Her successor will be announced shortly; in the meantime we wish the team the best of luck in Azerbaijan."
Sauber later released a second statement denying suggestions that their drivers, Marcus Ericsson and Pascal Wehrlein, were not being treated equally at the team.
"The owners and board of Sauber Motorsport AG take strong exception to speculative and widespread media reports today that our race drivers have not been, and are not being, treated equally.
"This is not only patently untrue, it would be contrary to the team's absolute and longstanding commitment to fair competition.
"These reports, attributed to anonymous "sources", are highly detrimental to both Marcus Ericsson and Pascal Wehrlein as well as to the management and all staff of the Sauber F1 Team."
