Toto Wolff is still working on offloading his stake in the Williams team.
Ever since the Austrian bought into Mercedes and began working as the German marque's F1 and motor racing chief, his more than 15 per cent stake in Williams has been quietly on the market.
In June, it emerged that 5 per cent of Wolff's stake was bought by US private healthcare businessman Brad Hollinger.
And now, the Daily Telegraph reports that Hollinger in fact has an additional 2 per cent option on the Grove based team worth about $5.7 million.
F1 business journalists Christian Sylt and Caroline Reid quoted Wolff as confirming: "I am now on slightly more than 10 per cent and Brad has an option to buy another 2pc. So if I find somebody who is suitable, maybe I will sell a little bit more."
