Ellen DeGeneres’ chat show is to end after 19 years on air.

The host broke the news in an interview with the Hollywood Reporter and said she had made the decision because the programme was “just not a challenge any more”.

However, the production faced accusations of a toxic work environment, prompting an internal review by Warner Bros.
