The 23-times Grand Slam winner, and seven-time F1 world champion, have come to an agreement that will see them invest in Chelsea should the bid be accepted.
According to Sky Sports, both Williams and Hamilton have pledged millions to the bid.
Talks regarding joining the bid have been ongoing for weeks, with the two being thought highly of because of their ‘experience building global sports brands’.
Sky sources state that, should the bid be approved and the takeover completed, Hamilton in particular is said to play a role in Chelsea’s efforts to ‘promote diversity, equity and inclusion’.
The final bidders have been told to provide evidence that would guarantee a minimum investment of £1bn to invest across the club’s infrastructure, its academy and women’s team.
