The Sussexes' most recent embarrassment could have been avoided, according to a PR expert. Another company has been using the name of Meghan Markle's new lifestyle brand, American Riviera Orchard, to sell adult colouring books online.

The Duchess of Sussex announced the new venture in March, revealing she would be creating a collection of preserves, jams and nut butters to sell, as well as homeware, home fragrance, pet products and cookware.

The company has yet to be fully launched. Instead, a Shopify page started by a mystery seller in America has been selling colouring books and financial planners under the name.

Jane Owen, celebrity PR expert, told The Mirror: “I think this is an embarrassment to the people running her company for sure. They should have been more careful to tie up all uses of the name legally so this could have been avoided.

“It shows a glaring lack of overall brand strategy which should have encompassed everything and predicted this kind of thing happening and prevented it. What I recommend they do is make every legal action to get this person to cease and desist. Then they buy up everything remotely connected to the name and put their marketing and advertising in to overdrive to compensate for this and do damage control on the brand name.”
