The world's richest sportswoman announced Monday that she had tested positive for Meldonium, a drug she said she had been taking since 2006 but was only added to the banned list this year.

Her sponsors were quick to react with US sportswear giant Nike, German luxury car maker Porsche and Swiss watchmaker TAG Heuer all halting their relationship with the former world number one.

The 28-year-old, whose rags-to-riches story was the stuff of Hollywood dreams, now risks a ban which could see her carefully constructed marketing strategy collapse.

The holder of five Grand Slams and 35 WTA titles, the Russian who arrived penniless with her family in the United States, is as much a businesswoman as a sportswoman.

Despite winning just two WTA titles in 2015 she was the highest paid sportswoman that year, earning USD 30 million mostly from advertising, according to American magazine Forbes. Her fortunes is estimated at USD 200 million.
In a sign of what the affair could mean to Sharapova's mass of money-spinning endorsements, Nike said it was 'saddened and surprised' by the news.
"We have decided to suspend our relationship with Maria while the investigation continues," the US sportswear giant said. Swiss watchmaker TAG Heuer followed by confirming they would not be renewing their marketing contract with Sharapova.
