Serena Williams and Lewis Hamilton have joined Martin Broughton’s bid to buy Chelsea. Their offer is one of three being considered by Roman Abramovich, club executives and the US bank Raine, which is overseeing the sale.
Williams, the winner of 23 tennis grand slam singles titles, and Hamilton, a seven-times Formula One world champion, have pledged what are understood to be small sums of money relative to a bid of more than £200m.
