Kellie Maloney, the transgender former boxing promoter, has clarified her belief that any athlete who has gone through male puberty should be banned from women’s sport.

The 71-year-old, who transitioned in 2014 after being known as Frank, also says, after talking to her daughters, that female-only toilets need improved protections.

Maloney had previously waded into the febrile Olympic boxing row, expressing concern for the welfare of Imane Khelif and Lin Yu-ting as they were engulfed in controversy. Algeria’s Khelif and Taiwan’s Lin are not trans, but a frenzied debate raged over the International Olympic Committee clearing the duo to compete in the women’s boxing in Paris. The pair had been disqualified from last year’s Women’s World Championships for failing to meet eligibility criteria on sex.

Maloney says the situation, however, is clear cut for trans athletes, writing in The Sunday Times ‘Life in a Day’ column that she is “against trans women who’ve gone through male puberty taking part in women’s sport”.

Maloney enjoyed a successful career as a boxing promoter, managing David Haye and Lennox Lewis, and writes in the column “if there were a pill that would have made me happy as a man, I’d have taken it”.

She detailed in The Sunday Times how she has listened to the opinion of her three daughters in the Algarve in Portugal before drawing conclusions about women’s sport and female toilets.

“I listen to my daughters and my friends here in Portugal — the girls are adamant that if someone wants to keep their penis they shouldn’t use women’s changing rooms,” Maloney writes. “That doesn’t always go down well with the trans community, but I think they’re right. I’m also against trans women who’ve gone through male puberty taking part in women’s sport. We have to accept that although our brains are female, we weren’t female from birth and our bodies are stronger.”
