Prince Harry and Meghan Markle were criticised over their actions after they put their Sussex brand "in its death throes", according to a royal commentator.

The Duke and Duchess of Sussex have embarked on their own projects this year, with Harry making solo appearances involving his life's passions and promoting his charity work.

Meghan has been working on her new lifestyle brand, American Riviera Orchard, and a new cookery show that was meant to coincide with it.

Now a series of royal experts have commented on how their efforts to promote their global brand as a "power couple" have not worked out for them.

Columnist Angela Mollard told Sky News Australia: "They went over to America, they were going to be a power couple, who were going to be the next Michelle and Barack Obama or the next George and Amal Clooney and that hasn't worked out for them.

"So they're very much looking into separate professional lives. They're sort of managing instead of being [seen as] a team, now being seen as two individuals, pursuing very different careers."

Sky News contributor Louise Roberts added: "Brand Sussex as a going concern together clearly is in its death throes.

"I think they both need to play to their strengths. Another mistake they've made is pinning their great romance and love story, the big story of redemption and freedom from the 'evil' Royal Family to their professional footprint."
