Prince Harry may return to the United Kingdom in September for another ceremony for his late mother, Princess Diana, and he may bring his wife, Meghan Markle. If it happens, it will be the first time the Duchess of Sussex will set her foot on British soil after the couple's explosive interview with Oprah Winfrey.

However, as there are rumors her revelations do not sit well with the royal family, she may not have a warm welcome from some Firm members. Markle herself made a number of allegations against Harry's family.

With that, royal expert Daniela Elser claims it is improbable that any royal family member will give her a gesture of conciliation.

According to Express.co.uk, Elser told News.com.au there might only be a "polite iciness" between Markle and Kate Middleton if they needed to reunite for the September Princess Diana event.

To recall, the former actor told Oprah Middleton made her cry during Princess Charlotte's bridesmaid dress fitting, though other reports said differently.

If the Sussexes and Cambridges indeed have a reunion, there may be a lot of interpretations coming from both sides. Of course, the media will surely make a number of stories from it.

When the two families were pictured together at the Commonwealth Day Service in March 2000, the iciness between them could be evidently felt. Even Middleton herself, who is known for being a pro when it comes to the royal game, cut Harry and Markle by not giving them attention despite being watched all over the world.

NZ Herald reported Harry planned to visit the U.K. in 10 weeks time to witness another memorial event for his mom. Several insiders claimed Markle would join him, though Lilibet would only be three months old at that time.

Several outlets said Harry and Prince William did not have any "heart-to-heart" talk when the Duke of Sussex last visited their home country. The alleged feud between them remains, though they have evidently put it aside during the unveiling of their mother's statue in the Sunken Garden of Kensington Palace July 2.

"Despite William and Harry coming together this week for the sole cause of commemorating their mother's legacy, Harry is very much on the outside," a source told The Daily Mirror. "They put on a show, did what they had to do to make sure the day went without a hitch and said goodbye."

Harry has now returned to the United States to be with his family.
