MEGHAN Markle is scheming the launch of her ultimate "weapon" to hurt Princess Kate and King Charles, claimed royal expert Tom Bower.
The royal biographer, who is known for making particularly stinging comments about the Sussexes, claimed the duchess, 42, is waiting to "drop another bomb" on the Royal Family.
Mr Bower, famous for his harsh opinions of the couple, sat down with Sun Royal Editor Matt Wilkinson on the
In particularly stinging comments, even for a long-standing critic of the couple, he said: "The future for the Sussexes is pretty grim, I think they're on a permanent decline.
"But whenever they need money, whenever they need publicity to stoke their reputation, they will drop another bomb.
"We're still waiting for Meghan's own autobiography, which I'm sure she's penning, she's a good writer, and it will be filled with vitriol and filled with lies.

"She will not tell the truth because she wants a sensational headline.
"That is the ultimate weapon she can deploy."
A spokesman for the couple denied the claims.
It comes as Mr Bower made more shocking claims that Meghan is an "agent of poison" and "doesn't seem to care" about her father Thomas Markle.

Despite drama propelled by Harry and Meghan's vile attacks in Spare, their Netflix documentary, and various bombshell interviews, the couple have stayed quiet for some time.
But when asked if the Sussexes have deliberately "reigned in" their attacks, Mr Bower claimed Meghan seems to be plotting for something bigger.
"I think she's allowed Harry to make the running, she's reserving herself for her autobiography, that's much better for her to be seen as the silent duchess, the silent weapon in reserve," he alleged.
"Harry has said some rather unfortunate stuff."
'DAMAGING TO THE ROYAL FAMILY'
Mr Bower spoke of the Sussexes trip to Nigeria, in what was later dubbed a 'faux royal tour'.
The couple touched down in Africa for their visit in May earlier this year and danced with schoolchildren while meeting locals and officials alike.
It came as part of in their efforts to get the country to host the Invictus Games in 2029.
After the couple's success, talks of more 'fake royal tours' were supposedly on the cards.

Mr Bower claimed: "The visit to Nigeria said it all. It said we are the Royal Family in a Commonwealth country, the most important probably in Africa," he alleged.
"That said it all, it was a brilliant coup. It put our Royal Family in a very difficult position, intentionally so.
"The presence of Harry and Meghan in Commonwealth countries will be absolutely damaging to the Royal Family, and of course that's a serious problem."
Archewell was contacted for comment.
It comes after shock cancer diagnoses rocked the Royal Family this year.
In February His Majesty bravely revealed he was diagnosed with the disease after going into the London Clinic for prostate surgery - the Palace previously confirmed it was not prostate cancer.
He has since returned to royal public duties with his usual energy and famous "workaholic approach".
On Wednesday, he presented the King's Speech and last month was in high spirits at his official birthday parade Trooping the Colour.
Meanwhile, Princess Kate has been largely out of the public eye since she went into the same hospital for major abdominal surgery in January.
The courageous royal later shared she was undergoing preventative chemotherapy in March.

'DETERMINED KATE'
By Summer Raemason
Royal expert Ingrid Seward told The Sun: "It was a long held promise that Kate would take Charlotte to the finals as a special treat.
"Kate felt guilty she hadn’t been able to spend as much time as she would have liked to be with the kids because of her exhaustion after her treatment.
"Charlotte has always loved tennis and mum Kate took her to Hurlingham when she was quite young to play tennis there.
"Kate was taught by her dad Michael. William was taught by his mum
Diana and tennis is a big family thing on both sides.
"So it is a super special day for Kate to be able to share it with Charlotte and much more fun for her to have Charlotte there and explain to her the details of what is going on.
"It’s also a distraction so she does not feel she is full and centre of everyone’s attention. Charlotte is there to deflect things away from her too.
"Kate was determined to be at Wimbledon on finals day if she possibly could.
"She knew she probably wouldn’t make both days. But I feel certain we might well see George in Germany tonight with his dad."
