TV host Ellen DeGeneres has apologised to staff following recent allegations that her show has a toxic workplace environment.
Following an investigation by WarnerMedia, several staff members are expected to be replaced on The Ellen DeGeneres Show after "deficiencies" in "the show's day-to-day management" were uncovered.
An inquiry was prompted after an article was published on Buzzfeed in which employees of the daytime show said it was a "toxic" place to work and that the environment was "dominated by fear". Several employees also shared their experiences of racism and intimidation.
In an email to staff, published by The Hollywood Reporter, DeGeneres apologised and said she was "committed to ensuring this does not happen again".
She wrote: "On day one of our show, I told everyone in our first meeting that The Ellen DeGeneres Show would be a place of happiness — no one would ever raise their voice, and everyone would be treated with respect.
"Obviously, something changed, and I am disappointed to learn that this has not been the case. And for that, I am sorry."
She also said that as her name "is on the show" she takes responsibility for everything that they do.
"My name is on the show and everything we do and I take responsibility for that. Alongside Warner Bros, we immediately began an internal investigation and we are taking steps, together, to correct the issues.
"As we've grown exponentially, I've not been able to stay on top of everything and relied on others to do their jobs as they knew I'd want them done. Clearly some didn't. That will now change and I'm committed to ensuring this does not happen again."
In a statement production company WarnerMedia said "several staffing changes" would take place as a result of its investigation.
