Meghan, the Duchess of Sussex, has announced her first post-royal role – narrating a documentary for Disney.

The film, called Elephant, will be available on streaming service Disney+ from 3 April.

The news was announced by the studio in a tweet on Thursday and later confirmed in a short statement from Buckingham Palace.

The documentary is being released just three days after Meghan and Prince Harry quit as senior royals.

The duchess was a successful actress, best known for her role as Rachel Zane in Suits, before joining the Royal Family.

A trailer for Elephant revealed that it “follows one family’s extraordinary 1,000 mile journey across Africa on an adventure that will change their lives”.

In July last year, Harry was filmed revealing his wife’s interest in being involved in a Disney project at the London premiere of the Lion King.

The footage showed the duke and duchess talking to the film’s director Jon Favreau as well as one of its stars Beyonce and her rapper husband Jay-Z.

Harry told them: “Next time, if anyone needs any extra voiceover work, we can make ourselves available.

Meghan added: “That’s really why we’re here – to pitch.”

In another clip, Harry tells Robert Iger, executive chairman of the Walt Disney Company: “You do know she does voiceovers?”

The Disney boss replied: “I did not know that,” and the duke went on to say: “You seem surprised. She’s really interested.”

The Times previously reported that Meghan had agreed a voiceover deal with Disney, which will make a donation to Elephants Without Borders, a wildlife charity supported by Harry.

Meghan and Harry will walk away from the monarchy for a life of personal and financial freedom next Tuesday and will no longer be able to use their HRH styles or use Sussex Royal as their brand.
