Williams has confirmed that Toto Wolff has left the team in order to take up a role with Mercedes.
Wolff will leave the company’s Board of Directors but will retain his shareholding.
A Williams statement confirms that 'Sir Frank Williams will continue to oversee the running of the Company with Toto’s responsibilities being shared between members of the Board’s Executive Committee.'
"I would like to thank Toto for his hard work, dedication and commitment to the team during his time as a Director of the Company. He was a key support to me as Executive Director last season, deputising at a number of races when I was unable to attend," said team principal Sir Frank Williams.
"However, positions such as the one offered to him by Mercedes do not come around often. Toto has a long history with them and I certainly was not going to stand in the way of him accepting this once in a lifetime opportunity".
"Toto will retain his shareholding in Williams and will always have a place at Grove but make no mistake; we will fight him hard on the racetrack! I am sure he will be a strong asset for Mercedes and on behalf of the whole team I would like to wish him the best of luck in his new role. I’m lucky to have a very professional group of people around me and the Company’s Executive Committee will continue the work they have been doing to ensure a successful future for the business."
