Prince Harry was eager to get to the stage of “marriage and kids” like Prince William, claims one royal expert.

The Duke and Duchess of Sussex are celebrating their sixth wedding anniversary today, but one expert has suggested that he “rushed” into their marriage.

The couple had only been together for a little over a year when they go engaged at the end of 2017, with their royal wedding taking place on May 19, 2018.

Speaking to the Times Radio, royal expert Dickie Arbier said: “My own personal opinion is that he rushed into the marriage.”

Dicussing Harry’s previous relationships, he said that many of the girls he dated didn’t want to be “in a goldfish bowl” and that he wanted to be like his brother.

He added that Harry was keen to have “marriage and kids” like William, who married Princess Kate back in 2011.

As reported by the Mirror, Mr Arbiter also adds that if Princess Diana were still alive at the time of Harry and Meghan’s wedding, Harry wouldn’t be where he is now. Speaking to the Radio Times two months ago, Mr Arbiter said: “If Diana had been alive, I’m going to stick my neck out here, and I doubt Harry would have married Meghan.”

He added: “Diana was very careful about her boys, they were her boys. She protected them, and she would have protected them against anybody she felt wasn’t the right person.”

The couple are likely to be celebrating their anniversary in private in the US, according to former royal butler Grant Harrold. Speaking to Fruity Slots, he explained: “Celebrations will probably be behind closed doors, maybe a dinner party with some friends or maybe with some friends or maybe just the two of them.”

Harry and Meghan have since welcomed two children together – Prince Archie, five, and Princess Lilibet, who will turn three next month.
