The 43-year-old former sprinter, who has triplegia, a form of cerebal palsy, said she "cried all the way home" after being challenged to prove her disability by ground staff in an incident she described as "beyond devastating".

In a post on Twitter, she wrote: "I’ve not complained on Twitter before.

"The order to publicly prove my disability incident by EasyJet yesterday was beyond devastating."

In a separate post, Warner added: "I was told 'you look completely normal. Why do you need help?'

"I cried all the way home.

"I don’t even know where to begin with a complaint."

EasyJet responded to Warner's complaint on social media, saying that the matter was being investigated.

According to inews, a company spokesperson later said: "We’re sorry to hear of Ms Warner’s experience.

"The agent involved is employed by Airport Handling and both he and they have assured us that he was trying to ascertain what assistance was required to help Ms Warner.

"However, this was clearly not handled as sensitively as we would have liked.

"We will investigate this with Airport Handling to ensure any lessons can be learned and changes are made to how they train their staff."

In a post on social media, two-time World Championship medallist Warner has since said: "Thanks everyone for all the kind words of support!

“EasyJet have been great so far and are on the case."
