Brexit Cost Serena Williams Almost $400K Low British pound affects Wimbledon prize By Arden Dier, Newser Staff Posted Jul 12, 2016 8:29 AM CDT 16 comments Comments Serena Williams falls after winning the women's singles final at Wimbledon. (Adam Davy/Pool Photo via AP) (Newser) – Serena Williams may be celebrating her 22nd Grand Slam title win at Wimbledon on Saturday, but she's probably cursing Brexit. Had last month's Brexit vote not sent the British pound into a nose dive, Williams' £2 million prize money would have been worth close to $3 million, rather than $2.6 million based on Sunday's conversion rate, reports MarketWatch. Her prize money as winner of the women's doubles title with sister Venus was also cut by about $33,000. As a Brit, men's Wimbledon champ Andy Murray probably isn't troubled by conversion rates.
