A royal expert is speaking out this week to claim that Prince Harry snubbed advice from his wife Meghan Markle to honor his late mother Princess Diana at the unveiling of a statue dedicated to her at Kensington Palace last week.

The Express reported that royal expert Richard Eden claimed that Harry ditched his grey suit, which he has constantly worn ever since he met Meghan Markle, to wear navy in support of his family.

“One thing that no one’s really picked up on is the level of co-ordination between the brothers,” Eden explained. “You might have noticed they were both wearing navy suits and Harry has been stuck to his grey suit ever since he met Meghan.”

“I think she suggested, ‘you look good in grey’ and he’s always worn it but on this occasion he wore navy,” he added. “That was Diana’s favorite suit for a man, it was navy. If you look at Prince Charles at her funeral, he didn’t wear black, he wore a navy suit and that’s because Diana liked him best in navy. There was definitely significance in that I think.”

The royal author went on to say that Harry and his older brother Prince William put on a “very good show” despite their rift. Royal expert Penny Junor agreed, saying it was “stunning” to see them together again.

“My guess is there’s quite a way to go, but it’s encouraging to see the two of them together, and with smiles on their faces. I think that is progress,” said Junor. “The dukes unveiled the bronze monument to their late mother in the palace’s Sunken Garden on what would have been her 60th birthday. I think the brothers put on a very, very good show.”

“I was expecting to see some sort of tight lips and some jaw muscles which we saw at the Commonwealth service in Westminster Abbey before Harry and Meghan left,” she continued. “They seemed to be reasonably relaxed with one another. They weren’t arms around each other, it wasn’t very touchy and there wasn’t, perhaps, the usual banter of times gone by. But had you not known there was a serious problem between the two of them, you wouldn’t necessarily have picked it up.”
