Prince Harry is back in his home country, and drama has seemingly followed the Duke of Sussex.

The younger son of King Charles III arrived in London without wife Meghan Markle by his side. The prince joined a panel on Tuesday for the 10th anniversary of the Invictus Games. The discussion, “The IGF Conversation: Realizing a Global Community,” aimed to highlight service personnel and their families.

While the event celebrated the 39-year-old’s cause, royal watchers told Fox News Digital Harry’s visit to the U.K. won’t spark a reconciliation with his family as the House of Windsor is rocked by health woes.

“Harry would love to reconnect with Kate [Middleton],” Christopher Andersen, author of “The King,” claimed to Fox News Digital.

“They were once extremely close, and Harry was hit hard by the news of her cancer diagnosis, which he learned about just the way the rest of us did, via Kate’s shocking video,” Andersen claimed. “Unfortunately, it doesn’t appear [Prince] William is willing to let his brother anywhere near his ailing wife.

“There was just too much drama between the brothers and their wives, and there is lingering bitterness on everyone’s part,” Andersen continued. “So, the chances of even a meeting between Harry and the rest of the royal family, much less some sort of reconciliation, seem extremely slim.”

In a video shared in March, the Princess of Wales, 42, revealed she’s battling a form of cancer. Her stunning announcement followed weeks of speculation about her health and whereabouts.

Middleton asked for “time, space and privacy” while she is treated for an unspecified type of cancer that was discovered after what she described as “major” surgery.

In February, Buckingham Palace announced the king had also been diagnosed with a form of cancer and is undergoing treatment. A “separate issue of concern” was identified during the monarch’s “benign prostate enlargement” procedure at the London Clinic.

“Subsequent diagnostic tests have identified a form of cancer,” the palace said in a statement at the time.

A spokesperson for the Duke of Sussex confirmed to Fox News Digital that the prince, 39, wouldn’t be meeting with his father.

“In response to the many inquiries and continued speculation on whether or not The Duke will meet with his father while in the UK this week, it, unfortunately, will not be possible due to His Majesty’s full programme,” the statement said.

“The Duke, of course, is understanding of his father’s diary of commitments and various other priorities and hopes to see him soon.”

While the Princess of Wales has been keeping a low profile during her recovery, the king has returned to public-facing duties as he continues his treatment.

“The king has softened a bit toward his younger son but hasn’t forgotten how Harry attacked [his wife] Queen Camilla in his memoir ‘Spare,’” Andersen claimed. “In his book, Harry branded her a ‘villain’ and described how both he and William begged their father not to marry her. For Charles, that is an unforgivable sin.”

Harry has had a troubled relationship with the royal family since he quit royal duties. According to the Duke and Duchess of Sussex, the unbearable intrusions and racist attitudes of the British media prompted the move to California in 2020.
