Former Olympian Caitlyn Jenner has said she was “blown away” by a frank and honest segment on trans rights by comedian John Oliver.

The English presenter, who has made his name across the pond, gave an overview of how to be polite to trans people for uninitiated.

He said: “If you’re still wondering, ‘What do I call a transgender person? It’s so confusing.’ Actually, it’s pretty simple: Call them whatever they want to be called.”

On trans people’s medical history, he said: “Some transgender people do go undergo hormone therapy or sex-reassignment surgery as part of their hormone therapy. Some do not.

“And, interestingly, their decision on this matter is, medically speaking, none of your f***ing business.”

Tweeting this weekend, Jenner, who is currently releasing a mini-series about her transition, commended the segment on the Last Week Tonight show.

She wrote: “Blown away by @iamjohnoliver and @LastWeekTonight’s show highlighting transgender rights. Bravo!”
