However, the special occasion was marred by reports that Prince Harry and Markle have delayed the reunion. “Yes, of course they were delayed an hour, it was because his father, now King Charles, told Prince William to extend the invitation because they found out that Meghan Markle had asked the US PR company to book an ‘alternative’ ride . So it was a last-minute call to stop it, it broke protocol (once again),” royal watcher Hilary Fordwich told Fox News Digital.

The Duke of Sussex is currently locked in a legal battle with the UK government as he battles for security following his decision to step down from his senior role as king. “If we see more of Harry and Meghan in the coming days, other than Monday’s function, we won’t get word of the appearance until the last minute,” royal expert Kinsey Schofield told Fox News Digital. “This is how they operate while in the UK Prince Harry is in a legal battle with the government over his security and I understand that the ‘negotiations’ that took place before Saturday’s joint appearance were related to security. he still fears for his family’s safety, but I think we’ll see more of that.” Kate Middleton, Prince William, Prince Harry and Meghan Markle came together to honor Queen Elizabeth II after her death.

But if the Sussexes felt overshadowed by the Cambridges, one can only imagine how they feel now. “ Andersen stressed the royal family was “on their best behavior” in an effort not to embarrass the family name following the death of Queen Elizabeth II. “William and Harry used to laugh and joke almost every time they met. That playful brotherly shell that was the hallmark of their relationship is not much in evidence now,” she told Fox News Digital. “They’re nice enough to each other, but that’s about it. They’re all on their best behavior right now, careful not to do anything that would embarrass or upset their grandmother.” King Charles III appeared to extend his own olive branch to Prince Harry by mentioning his son and Markle in his first speech after taking the throne. However, it is unclear whether any further steps will be taken to mend the father-son relationship. “Charles has extended an olive branch to Harry and Meghan by mentioning them in his accession speech, but it’s hard to imagine much will come of it,” Andersen said. “The palace is holding its collective breath, waiting to see what new bombshells are contained in Harry’s forthcoming memoir.” CLICK HERE TO GET THE FOX NEWS APP The outing marks the first time the Prince and Princess of Wales and the Duke and Duchess of Sussex have been photographed together since March 2020.

I’ve worn many hats over the years, literally and figuratively, and I hope that in telling my story—the highs and the lows, the mistakes, the lessons— I can help show that no matter where we come from, we have more in common than we think,” he said in a press release at the time. “I am deeply grateful for the opportunity to share what I have learned throughout my life so far and excited for people to read a first-hand account of my life that is accurate and completely true.” Lauryn Overhultz is an entertainment writer for Fox News Digital.
