Senior entertainment reporter Bronte Coy, who broke the story on news.com.au, reported that Meghan being offered a part in a "top secret" UK production had played a "significant" role in the family's return.

"This is such a key part of the puzzle," she told BBC Radio 4's Today programme on Friday.

"I think when we all heard that news that Harry and Meghan were moving here, and within a matter of days, and the kids were enrolled in school, everyone was asking, what is Meghan going to be doing?"

"I'm told it's significant, and she's very excited about it," Coy said about Meghan's latest project.

Coy also suggested she thinks "we will find out relatively soon".

As an actress, Meghan was best known for her part in the US legal drama, Suits, in which she played lawyer, Rachel Zane, for seven seasons. Her last episode of Suits aired in 2018.

The duchess put her acting career on hold after her marriage to Prince Harry. At the time, she told the BBC that she did not view quitting acting as giving anything up, but rather as "a new chapter".

She recently returned to acting for the first time in nearly a decade, with a cameo as herself in the upcoming comedy Close Personal Friends, which stars Lily Collins and Brie Larson.

A return to acting could be lucrative for Meghan. The BBC understands that while based in the UK she also hopes to expand the global reach of her US-based lifestyle and cooking brand, As Ever.
