Prince Harry and Meghan Markle extended an “olive branch” to Prince William and Kate Middleton. However, the two latter British Royals were reportedly “forced to reject” it.

Express UK said that the so-called “olive branch” was the invitation the former working royals gave the Duke and Duchess of Cambridge for their daughter’s first birthday. But, due to their duties and responsibilities during the Platinum Jubilee celebrations, they were not able to make it to the Sussexes’ private event.

As reported, the future King and Queen Consort went to Wales earlier that day, along with two of their children. They made an appearance at Cardiff Castle before attending the Platinum Party at the Palace.

Some sources believe Prince William and Kate Middleton’s children did not see their cousins from Prince Harry and Meghan Markle during the historic celebrations. The publication noted that the assertions emerged in a previous report from Page Six.

It all reportedly comes as the alleged rift between the Duke of Cambridge and Duke of Sussex remains ongoing.

A royal insider consequently told the column that “things are still fraught” for the royal siblings. It was also claimed that the oldest Wales prince remains “wary of spending any time alone” with his brother “as you never quite know what may be reported back afterwards.”

Despite not being able to attend the Sussexes’ private event at Frogmore Cottage, Prince William and Kate Middleton shared their birthday greeting for Prince Harry and Meghan Markle’s youngest child on social media.

On Twitter, the royal couple wished the youngest member of the Sussex household a “a very happy birthday.” The post also included a red balloon emoji.

Several members of the British Royal Family followed suit and shared their respective greetings on their social media accounts. Page Six said that these include Queen Elizabeth II, Prince Charles, and Camilla Parker Bowles.

Prince Harry and Meghan Markle celebrated their youngest child’s first birthday on Saturday. They did not attend the Platinum Jubilee events set for the day to mark the special occasion.

The Sussexes have yet to share the details of how they spent the day at Frogmore Cottage. But, sources told The Sun that the Duke and Duchess of Sussex held an “informal garden party” at the Windsor estate.

As reported, the private event “was a lovely do, and had everything you’d expect from a child’s birthday party.” It was also added that “there was no formal entertainment” as the “idea was for it to be very relaxed and casual.”

While Prince William and Kate Middleton, along with their children, were not in attendance, some other members of the British Royal Family were reportedly there to celebrate the young Sussex’s special day.
