When is Caitlyn Jenner addressing the House of Commons about diversity and what is she expected to say in her speech?
FORMER Olympic gold medallist and US reality TV star Caitlyn Jenner will deliver a lecture on diversity in the House of Commons today.
Here's the lowdown on the woman dubbed "one of the most high profile transgender people in the world" - and what she's expected to say in her speech.
Who is Caitlyn Jenner?
Caitlyn, 68, is a transgender activist who made a documentary, I Am Cait, about her transition.
In a 2015 interview with Diane Sawyer on ABC's 20/20, she told how she was transitioning from Bruce to Caitlyn.
She revealed that she had been dealing with gender dysphoria since she was a child.
A few months after the televised interview, Caitlyn told Vanity Fair that her transition was authentic and not a means for attention.
Jenner has two daughters from her marriage to Kris Kardashian - Kendall and Kylie - and is also the step-parent to Kim, Kourtney, Khloe and Rob Kardashian.
Why is Caitlyn giving a speech in the House of Commons?
The transgender activist will be giving Channel 4s diversity talk on Wednesday (May 9) in the Churchill Room at the House of Commons.
The lecture has been previously given by The Wire star Idris Elba and The Night Of star Riz Ahmed.
Previous versions of the speech have been screened live on YouTube.
Caitlyn's speech will come as Channel 4 kicks off its Genderquake season, which is designed to raise awareness and open up the debate on gender issues.
A Channel 4 spokesman said: "The aim of the Channel 4 diversity lecture is to raise awareness and stimulate public debate about diversity issues.
"Caitlyn Jenner is one of the most high profile transgender people in the world and her transition brought transgender issues into the mainstream, helping to stimulate debate and increase awareness."

What are Caitlyn's political views?
Caitlyn has not been shy of voicing her political views in the past, admitting that she voted for Donald Trump and hoped his administration would change its tune on LGBTQ issues.
But the Republican recently admitted that she regretted the decision,telling Newsweek that Trump and his administration have "set our community back 20 years".
She said: "As far as trans issues, this administration has been the worst ever,' Jenner told Newsweek at the Champions of Jewish Values International Awards Gala.
"They've set our community back 20 years, easily. It's going to be hard to change, but we've been through these types of things before and we'll continue to fight it."
