The Oxford Union has been urged to uphold "rigorous debate" and free speech in posing a series of questions to the Olympic boxer Imane Khelif when she appears at the university on Sunday.
Khelif was the winner of a hugely controversial gold medal in the women's welterweight competition in Paris after the International Boxing Association said that she had been disqualified from last year's world championships for failing gender eligibility criteria.
The IBA says that its results showed XY chromosomes. Following reports of unverified leaked medical documents that also claim she has XY chromosomes, the International Olympic Committee said that Khelif was taking "legal action against individuals who commented on her situation during the Olympic Games Paris 2024, and is also preparing a lawsuit in response to the latest reporting".
Khelif, 25, maintains she is a woman, and her father produced her birth certificate which states that she was born female.
Mara Yamauchi, a former Olympic marathon runner and student at the University of Oxford, has written directly to the Oxford Union to suggest a series of questions. She has also asked the Union to invite the boxers who lost to Khelif in Paris.
"The Oxford Union, as a bastion of free speech, is of course free to invite anyone it wishes," says Yamauchi's letter. "[It] is an excellent opportunity to hear directly from Khelif. The Union's slogan is 'Celebrating 200 years of Free Speech', so I hope you will give sufficient time for these and similar questions and allow for robust scrutiny."
The suggested questions include why Khelif withdrew an appeal to the Court of Arbitration for Sport when she was first banned by the IBA, whether she would provide evidence of a sex test, and whether she supported Caster Semenya's inclusion in previous Olympic Games.
Semenya, who was a gold medallist in the 800m in 2012 and 2016, is now ineligible after World Athletics ruled that athletes with differences in sexual development must reduce their testosterone level to below 2.5 nanomoles per litre.
The IBA was stripped of recognition by the IOC last year over governance failures. That meant it was the IOC which ran - and set the entry criteria for - the Olympic boxing tournament in Paris.
The IOC based its gender eligibility for the boxing tournament on the passport details of athletes.
