The Duke and Duchess of Sussex have tried their hand at several business ventures but author Mark Borkowski told The Sun’s Royal ExThe Duke and Duchess of Sussex have tried their hand at several business ventures but author Mark Borkowski told The Sun’s Royal Exclusive show it’s “like trying to brand snow in a hail storm”.

The couple raised eyebrows when they ‘reinvented’ themselves and controversially changed the Archewell website using their royal titles.

Their personal projects have since swirled in drama, from Megan’s promise of a cooking show about love and friendship – to Harry’s series on the elite sport polo.

Talking to The Sun’s royal editor, Matt Wilkinson, Mr Borkowski said: “They stuck together and didn’t take advice, and it became a catalogue of these things, they over-promised a lot of their products they were going to bring.

“It started off being this brand that was going to set up a well-meaning foundation, they’re going to do this great work.

clusive show it’s “like trying to brand snow in a hail storm”.

“It was over-hyped and over-promised, and when you over-promise, then under-deliver, then you become the story.

“There’s a feeding frenzy around the negativity, there was never any positivity.”

He added: “They cannot carry on doing the same thing, what’s happened to this new jam brand that she’s bringing out? I mean how ridiculous is that, who does she want to be? The next Martha Stewart?

“I think you see desperation slipping in now and that should be an indication to say ‘let’s start again and learn from the royal family, post Diana’, bring people in who know their stuff.

“Build a team out of that, instead of ‘yes people’ to do what you want, backed up by some Rottweiler of a lawyer who’s going to send out letters to every last person.

“The way they’re going about it is akin to trying to brand snow in a hail storm.”

Mr Borkowski previously claimed on the Royal Exclusive show he believed Meghan thought married life with Prince Harry would be that of a Disney Princess – rather than dutiful royal.

He said the Duchess of Sussex didn’t get the “tiaras and ballrooms” she’d bargained for.

“It’s a job and I think that was the first thing that came apart,” said the expert.

It comes after Meghan’s lifestyle brand American Riviera Orchard suffered a fresh blow earlier this month.

Since announcing the company, the former Suits actress is yet to roll out anything other than jams and dog biscuits – products that have only been gifted to her A-lister pals so far.

Meghan has also faced multiple hurdles in her launch, including ‘struggling’ to secure a CEO, her team filling in the official forms incorrectly, and failing to send enough cash.

These issues came in addition to a bitter dispute over exclusive rights to the name American Riviera Orchard.

Her team, led by top US attorney Marjorie Witter Norman under Meghan’s fledgling Mama Knows Best LLC firm, applied to the Patent and Trademark Office in the States for legal protection to exclusively trade using the name ‘American Riviera Orchard’.

But the application, filed in March, has been rejected and now she has three months to amend the request – or it will be removed from the register.

She has been told she can’t have exclusive rights to ‘American Riviera’ because it is a commonly used place name to describe the California coast.

Correspondence from the US trade arm, seen by The Sun, states: “The following wording in the identification of goods is indefinite and must be amended to further specify they goods: Garden tool gift set, comprised of hand tools for gardening International….Stationery sets; Embossers for paper stationery; Blank journals …. Kits comprised of edible oils, fats, preserves, spreads, and butters; Kits comprised of ingredients for making baked goods.”

Other goods deemed ‘too broad’ are: “cocktail napkins, pans, cooking utensils, namely, strainers, spoons, forks, spatulas, tongs, spreaders, whisks, soap dispensers.”

The document also points out errors with applications for “gift wrap of fabric or textile” and “meditation blankets; yoga blankets”.

The couple also faced backlash last month in amid their Colombia tour – after moaning about security fears while travelling in the UK.

During their visit they discussed their new project, The Parents Network, which aims to support families who have lost their children to online harm.

On their final engagement of the tour, the Sussexes also toured the Centro de Rehabilitación Inclusiva for a training session with the Invictus Games’ Team Colombia.

The priceless work the duke’s Invictus Games achieves has always been highly praised, and he is set to return to the UK in 2027 for the next official ceremony.

Harry is currently in New York and was pictured during a high-level dinner organised by the World Health Organization (WHO) on Sunday.

The event was to honour survivors of childhood violence and discuss its impact on mental health.

He is due to appear with an African conservation group, a young people’s charity named after his mum Diana and the Halo Trust, a landmine charity which was close to Di’s heart.

A spokesperson for the Sussexes was approached for comment.
