Meghan Markle has been heavily criticised by a royal author over her efforts to rebrand her image towards the public.

Princess Diana's biographer and ex-Vanity Fair editor Tina Brown, who's known for being critical about the Duke and Duchess of Sussex, gave out a scathing comment regarding Meghan's future if her husband, Prince Harry, were to make any progress in reconciling with the Royal Family.

The author claimed that a royal return could pose a "great face-saver" for the duchess, who is still yet to fully launch her lifestyle brand American Riviera Orchard - despite it being announced several months ago.She also has a cooking show on Netflix in the near future.

Harry and Meghan have been estranged from the royals for a number of years now.

However, Ms Brown stated that King Charles's Private Secretary, Sir Clive Alderton, is eyeing up retirement which could in turn create a fresh path back into the royal fold for the duke.

The duke did not speak fondly of Sir Clive in his memoir, Spare, branding him "weedy" and "arrogant".

Harry wrote: "The Wasp [Sir Clive] was lanky, charming, arrogant, a ball of jazzy energy. He was great at pretending to be polite, even servile.

"Because he seemed so weedy, so self-effacing, you might be tempted to push back, insist on your point, and that was when he'd put you on his list.

"A short time later, without warning, he'd give you such a stab with his outsized stinger that you'd cry out in confusion. Where the f*** did that come from?

Ms Brown wrote on her Fresh Hell Substack blog: "If Alderton goes, it could create a new, friendlier path for negotiations with Harry to be given the security protection he seeks and to resume some curtailed version of his royal duties.

"It could also represent a great face-saver for Meghan who must realise by now that the dull demands of second-division royalty are less onerous than grinding out serial rebranding flops."
