More explosive claims have surfaced, shining a light on the royal rift between Prince William and Kate Middleton and Prince Harry and Meghan Markle.
According to new book Royals At War, the Duchess of Cambridge warned Harry not to wed the Hollywood actress amid a wild spending spree.

After beginning to date Meghan in 2016, concerns immediately arose for Prince William, who reportedly asked Harry: “Is she the right one?”
Meanwhile, Duchess Kate urged Harry to take things slow in his newfound whirlwind romance.
The novel claims Harry took the question as a deliberate slight.
Driven by a desire to protect Meghan, one insider sighted in the book tells: “Harry feels he couldn’t protect his mother, so he’s going all out to protect his wife. He is so sensitive he often sees criticism or negativity where there isn’t any.”

But it was the Duke of Sussex’s lavish spending after meeting Meghan that really drove the divide between the brothers.
“Harry’s [spending] transformation is revealed as one of the fundamental factors behind the deep fissure that opened between him and his brother, Prince William,” authors Dylan Howard and Andy Tillett write.
Harry reportedly spent over £6,000 on acupuncture “as part of a health drive”, with Meghan pushing the Duke to spend on other wellness therapies, including massages and aromatherapy.
Meanwhile, Meghan is said to have spent over £478,920 on maternity clothes after falling pregnant with their son, Archie. Not to mention a £33,000 three-night babymoon at a luxury spa in Hampshire.

When the couple moved into Frogmore Cottage on the grounds of Windsor Castle, the cost of refurbishment caused controversy, with the Queen said to be “privately unhappy” over the expenditure. The couple are now expected to pay back the cost of works as part of their Megxit deal.
“The fact that Meghan splashed so much cash rang alarm bells with the traditionally conservative Queen Elizabeth,” said the authors.
“Growing up in the war left the monarch with a built-in sense of frugality and economy, despite being one of the richest women in the world.”

It’s the opinion of the authors that the entire fallout could have been avoided completely if Harry had been able to see that many of the royal officials were actually fans of Meghan.
“The rifts that eventually opened up in the royal family after Meghan arrived could have been avoided if Harry was able to empathise and take his brother’s concerns in the spirit they were intended.”
