Maria Sharapova has been suspended as a Goodwill Ambassador by the United Nations as a result of her failed drugs test.
The Russian tested positive for meldonium in January, and still faces a potentially lengthy ban from competition.
The United Nations Development Programme said it had suspended Sharapova from “any planned activities while the investigation continues.”
It added that it “remains grateful for her support of our work”.
Sharapova has held the position with the UNDP since 2007, assisting the organisation’s fight to eradicate poverty and inequality across the globe.
The 28-year-old has also lost several sponsorships in the wake of her positive test, including Nike, Tag Heuer and Porsche.
