Sebastian Coe promised to be ‘guided by science’ when it comes to sport’s most divisive issue. But World Athletics’ solution is clearly designed to protect it from legal action too

During a star-spangled athletics career, Sebastian Coe rarely snatched defeat from the jaws of victory. The most famous exception came at the Olympic 800m final in Moscow where he made so many tactical missteps that his father and coach, Peter, used a coarse four-letter word to describe his run. However this weekend Lord Coe became reacquainted with similar levels of opprobrium after World Athletics’ proposed solution to sport’s most divisive issue became public.

For months, as the World Athletics president Coe has strongly hinted that trans women and athletes with differences of sexual development (DSD), who are 46 XY with male testes but were reported female at birth, should only compete in female sport if the science shows it is fair. “Biology trumps identity,” he said in the summer. “If we ever get pushed into a corner to that point where we’re making a judgment about fairness or inclusion, I will always fall down on the side of fairness.” Just in case there was any doubt, Coe also promised to “be guided by the science”, before adding: “Fairness is non-negotiable.”
