Williams has announced Simon Roberts as its new acting team principal after Claire Williams stood down as deputy team principal on Monday.
The Williams family sold its team to investment firm Dorilton Capital last month and opted to stand down from the running of the company following last weekend's Italian Grand Prix.
Founder Frank Williams had held the position of team principal, but his daughter, Claire, was involved in the day-to-day running of the team as deputy team principal.
Roberts will now take over as acting team principal during a transitional period after joining the team as its sporting director in May.
