Amid reports suggesting Prince William and Prince Harry’s relationship is suffering from an ongoing rift, the Duke of Cambridge seemingly fueled feud rumors while attending a charity polo match earlier this week.

Following Prince Harry and Meghan Markle’s royal wedding, the Duchess of Sussex was rumored to be responsible for starting a royal feud with Prince William and Kate Middleton. However, royal experts believe the feud is between the brothers, and that there is still some tension between them.

According to the Express UK, William appeared to snub Harry after their team won a charity polo match on Wednesday. Harry reportedly patted his brother on the back following their victory, but William failed to show his brother the same enthusiasm.

When the two came together to pose for cameras, Prince Harry placed his hand on his brother’s back, but, William made no attempts to reach out to his sibling.

Prior to the snub, William and Harry’s relationship appeared to be on rocks at Archie Harrison Mountbatten-Windsor’s christening. Several royal experts noticed the Duke of Cambridge looked “grumpy” while posing for a photo at the event.

During an appearance on ITV’s “Lorraine,” Daily Mirror’s Royal editor, Russell Myers claimed William didn’t look happy in the christening photo. “What a lovely touch from Kate Middleton, that she wore the same earrings that Diana had worn to Harry’s christening,” he noted.

“They all look fantastic, apart from William, he looks a bit grumpy. He has been criticized a little bit,” he added.

Nonetheless, Myers suggested the brothers would be on better terms once they met up at the polo match. “They are knocking back during the week together, they are going to be at a polo match - maybe that will squash the beef,” he explained.

However, it seems there was still some tension between the brothers during the event. Prince Harry and Meghan have already split charities with Prince William and Kate Middleton, and it appears the couples are continuing to distance themselves from one another.

The palace has not commented on the state of the siblings’ relationship.
