Maria Sharapova has been suspended as a goodwill ambassador by the United Nations after the former world No.1 admitted she had tested positive for the banned substance meldonium at this year's Australian Open.
The UN Development Programme (UNDP), for which the five-times grand slam winner became a goodwill ambassador in February 2007, suspended the Russian until the outcome of the investigation into her case is known.
"In light of Ms Sharapova's recent announcement, we last week suspended her role as a Goodwill Ambassador and any planned activities while the investigation continues. We wish Ms Sharapova the best," the UNDP told Reuters in an emailed statement.
Sharapova's work with the UN focused mainly on helping survivors of the 1986 Chernobyl disaster, but links to her profile on the UN's official website were not working on Tuesday.
"The United Nations Development Programme remains grateful to Maria Sharapova for her support of our work, especially around the Chernobyl nuclear disaster recovery," the statement added.
