Two-time Grand Slam champion Simona Halep has questioned the "big difference" in how tennis doping cases are handled after world number two Iga Swiatek received a one-month ban.
The International Tennis Integrity Agency (ITIA) announced on Thursday that Swiatek had accepted a one-month suspension after testing positive for banned substance trimetazidine (TMZ).
Halep, who was out of action for more than 18 months following two separate anti-doping violations, has criticised the ITIA for having "completely different approaches".
"I stand and ask myself, why is there such a big difference in treatment and judgment?
