Royal writer Emily Andrews shared more photos of the interactions on Twitter, with the comment: “Prince Harry, who was also at the private lunch, noticeably hung back. He walked in with Ivanka (was he supposed to show her round the exhibition?? or maybe they sat next to each other at lunch) and then drifted off to talk to the Lord Chamberlain (the Earl Peel).”

Commentator Ingrid Seward blasted the prince’s allegedly poor manners, per The Sun. “He appears to be behaving in a rather immature way and letting his personal animosity take over from his natural good manners,” she said.

“Whatever his personal feelings, it’s his duty to support the Queen regardless and take a tip from his grandmother who has never allowed her personal feelings to interfere with her duty,” she continued. “It’s bad manners and rude.”
