Prince Harry not invited to cousin's wedding because of Prince William?

Prince Harry wasn’t invited to cousin Peter Phillips’ wedding because of Prince William.

Insiders tell Naughty But Nice that William would not attend the wedding ceremony if his brother was there.

“There was never going to be a scenario where William and Harry spent the day together,” one royal insider says. “That ship has sailed.”

As per the tipsters, once that reality was accepted, the decision became easier.

“Nobody sat around debating this,” says an insider. “William is the heir. William is the priority. Every single time.”

“One brother is the future of the institution,” the source adds. “The other walked away from it.”

Sources further say that the royal family's priority was to ensure that the Prince of Wales felt comfortable attending his cousin's wedding day.

“The calculation was straightforward,” the insider says. “Keep William happy and the event goes ahead without a problem.”

The confidant adds that the brothers' relationship remains so fractured, and even relatives have given up trying to force interactions.

“People still talk about reconciliation,” says an insider. “William isn’t interested in sharing a room, a table, or a photo opportunity with Harry.”

For those unversed, Peter Phillips will tie the knot with Harriet Sperling on June 6 in a private ceremony in England.
