Mercedes motorsport boss Toto Wolff has sold a further stake in the Williams Formula One team to American healthcare executive Brad Hollinger.
Vibra Healthcare owner Hollinger had already purchased a five percent stake from Wolff in June last year.
Wolff has now sold a further five percent stake after Hollinger exercised an option, leaving the F1 team boss with another five percent of the Grove-based squad.
Team founder Frank Williams remains the majority stake holder with 52 percent, while Patrick Head is now level with Hollinger on 10 percent.
Wolff, a former executive director at Williams, said he intends to keep the remaining shares.
