Davies said: “FINA are about to bring out some very promising new rules and the World Swimming Coaches Association are also highlighting that they want fairness for biological females.

“So, hopefully we won’t need to go to the courts. But, yes, absolutely that has to be an option.

“Sadly, I said at the start of this years ago, it might take a few high-level famous female Olympians being beaten by average trans athletes before the general public say enough is enough.

“I was trying to avoid weeks like this last one in the USA by stating the obvious outcome.

“It’s ridiculous young female swimmers have been used this way.”

Denouncing the International Olympic Committee’s decision to allow individual sports to determine their own transgender policies, she added: “This is firmly at the feet of the IOC’s lack of good governance to look after the rights of female athletes. They have discriminated against biological women and girls.”
