Reports of a feud between Meghan and Kate stem from differing approaches to royal life, and specific incidents surrounding the 2018 royal wedding, including disputes over bridesmaid dresses.

TalkTV presenter Kevin O'Sullivan has since suggested Princess Kate bombshell move could devastate the Sussexes. Speaking on his show on Thursday, the broadcaster claimed there is "another saga haunting Harry".

He commented: "But there's another sorry saga haunting hapless Harry. And that's her ladyship's long running 'feud' with the Princess of Wales. Fought on the trans-atlantic battlefield of publicity, it's a war that 'confident Kate' is barely bothered by."

When the Princess of Wales returned to royal duties with an appearance at the Trooping the Colour ceremony following her cancer treatment, Kevin suggested Meghan attempted to "knock Kate off the front pages" with the launch of her dog biscuits.

Kate announced this week she is embarking on a rare solo overseas trip, but Kevin claimed in "eerily comparable circumstances", Meghan posted a photo of their son Archie as a baby with Prince Harry, to mark their child's seventh birthday.

"The image unleashed as a weapon of media mass destruction amid his mother's ongoing conflict [with the future Queen]," Kevin claimed.

The TalkTV host predicts Kate could potentially urge William to strip Harry and Meghan of their Sussex titles.

"And when she wears the crown," he went on, "insiders predict that Kate will have no hesitation urging William to strip his estranged brother Harry and Meghan of their titles they continue to commericialise."

However, other royal insiders have claimed William has no intention of removing Harry and Meghan's titles.
