Woman who accused Senegal's opposition leader of rape urges justice
"If Ousmane Sonko has never slept with me, let him swear on the Koran," said the young woman, in the interview carried by several private television channels in the West African state.
Sarr added that she had fallen pregnant by Sonko.
Usually seen as a haven of stability of a volatile region, Senegal was rocked by the worst unrest it had seen in years after Sonko was arrested on March 3.
He had been due to appear before a judge in relation to Sarr's separate rape charge, which she had filed in February.
At least five people died in the clashes between opposition supporters and security forces that followed Sonko's arrest.
The unrest died down only after a judge freed the 46-year-old from detention on March 8.
But the judge also formally charged him with rape, paving the way for an investigation.
To many opposition supporters, Sonko's legal troubles fit a perceived pattern of politically motivated court cases against rivals of President Macky Sall.
Sarr said Wednesday she had never met the president.
"Let the Senegalese know that there is no conspiracy and that President Macky Sall is not involved in this case," Sarr said.
While she was surprised at the scale of the reaction to the affair, she said she was keen for the legal case to proceed.
"The judiciary needs to do its work," she said. "I am in a hurry for it to do so because I am not free".
