The broadcaster wrote: “BREAKING: A biological male just won an Olympic gold medal in a women’s boxing competition.
“Congrats to everyone who supported this travesty.”
By declaring Khelif a “biological male”, Piers sparked backlash from furious fans.
Taking to the comments, @_muhammadzain1 hit back: “She’s a woman, if she was trans she’d be in prison as it is against the law in her country.”
@marfani1987 slammed: “Shame on you. Instead of supporting and congratulating, you are taunting Imane Khelif.”
Morgan responded to the criticism and posted: ”Imane was banned from the World Championships after testing positive for male XY chromosomes. She didn’t appeal it.
“If she’s a biological woman, she should take another test now and prove it. Spoiler alert: she won’t.”
Khelif’s victory comes nine days after she won her first-round bout over Italy’s Angela Carini in just 46 seconds, sparking a global outcry.
Following her victory, Khelif shut down naysayers and declared: “I am fully qualified. I am a woman like any other woman. I was born a woman, I lived as a woman, I competed as woman – there is no doubt.
“There are enemies of success of course. That gives my success a special taste.”
