Maria Sharapova will face an anti-doping panel in London on Wednesday after taking the banned drug Meldonium.

The 29-year-old Russian failed a doping test after the Australian Open in January.

Meldonium, which the Russian said she was using to treat a heart condition, was added to the World Anti-Doping Agency’s banned list on January 1 this year, but Sharapova continued taking the drug past that date as she said she did not know it had been added to the banned substance list.
