Meghan Markle's 'petty rivalry' with King Charles is 'beneath the monarch'

The monarch already sells organic jams via The Highgrove Shop and through his Duchy Originals line at Waitrose supermarkets.

Bond - who is a veteran palace insider - has profusely denied the claims.

"I absolutely refuse to buy into suggestions of a petty rivalry between Meghan's products and the release of new products from the Highgrove estate," she told OK! Magazine.

"Highgrove has been coming up with new products for years now.

"The marketing might have become more sophisticated over time.

"But there has always been publicity about the organic produce from the farm and gardens."

LATEST DEVELOPMENTS:

• Meghan and Harry’s inner circle ‘falling apart’ as Sussexes prepare for last roll of the dice
• Prince Harry 'petrified of losing Meghan Markle' as 'angry' duke tipped for UK return
• King urged to reconsider his plan after Anne's absence exposed major flaw

The commentator added that the "jam wars" are a "load of old nonsense".

"I really don't think that Charles or his marketing people would sink so low as to try to deliberately compete with or scupper Meghan and her team," Bond said.

"Why would Charles want to make things worse than they already are?

"So I think it's a load of old nonsense and would be beneath him."

It comes as sales of Charles's jams have reportedly spiked since Meghan's American Riviera Orchard announced the release of their product.

Meghan has teased more jams in the future from her lifestyle brand.

She has also suggested that a line of dog food could be launched.

However, no details have been confirmed on whether any new products will be released.
