The 44-year-old, along with her husband, Prince Harry, 41, and their two children, Archie, seven, and Lilibet, five, are set to return to the UK between July 6 and July 10 after living in the United States for four years.
The family will be embarking on the transatlantic trip to attend the One Year To Go Invictus events in Birmingham.

The Games, founded by Prince Harry in 2014, are held biennially at locations across the globe and feature multiple sporting events for wounded, injured and sick military service personnel.
While the Duchess of Sussex’s schedule for the trip has not been confirmed, she is expected to show face alongside her husband at London’s Royal Hospital Chelsea and an Invictus event at Birmingham’s National Exhibition Centre.
Now, a PR expert has issued a three-word warning to the former Suits actress, telling the Daily Express that she should keep in mind that the visit “is about Harry”.
“Unlike some of their previous appearances, this trip isn’t at all about Meghan. It’s about Harry, Invictus, and the work he’s spent years building,” Renae Smith, founder of PR and branding agency The Atticism, told the publication.

She added that one of the smartest thing Meghan could do from a PR perspective is “let him shine”.
“The only thing I would caution against is forgetting whose stage this is. Invictus belongs to Harry. The veterans belong to Harry.”
Smith insisted that this wasn’t the time “for lifestyle branding, personal messaging or creating viral moments”, but rather an opportunity to be “a supportive partner”.
“If she does that, I’d consider the trip a PR success.”
News.com.au first reported the news of the Sussexes’ UK return last month, with a source close to Harry revealing he felt “great sadness” that safety concerns had stopped his wife and children from travelling to the United Kingdom with him in the past.
“It’s been a real point of great sadness – for Harry especially – that he’s been unable to bring his wife and kids back to the UK safely to reconnect with friends and family, but anyone would understand his desire to put their safety first,” the source said.
“He would love to introduce the children to his wider family, to show them the UK, where he grew up – his homeland. That would be a natural thing for any parent.”
