Prince Philip accepted Princess Diana into the royal fold while she was married to Prince Charles. But royal fans are wondering if the two managed to maintain a relationship even after the Prince and Princess of Wales divorced.

On the online forum site Quora, one royal fan said that she thinks Prince Philip continued to have a relationship with his former daughter-in-law. Laura Warwick Martin, a former fundraiser, that the two royals even kept their correspondence going.

“Apparently, he was very concerned about her, maybe he felt a little guilty that he had pushed the marriage between her and Charles, probably he was aware that she had no father figure in her life and her nearest male relative was as useful as chocolate teapot,” she said.

Regardless of Prince Philip’s reasoning, Warwick is convinced that he encouraged Princess Diana to reach out to him if she needed someone to be there for her.

But Selene Daws, a former teacher, thinks otherwise. She said that Prince Philip must have burned the bridges with Princess Diana after she gave a controversial interview for Panorama in 1995. Following the incident, the Queen encouraged the divorce and lent Prince Charles the money to pay for the settlement.

Janet Devers, a retired Ford employee, echoed Daws’ sentiments. She said that Prince Philip cut ties with Princess Diana for good after her interview with Panorama was released.

“After the TV thing, Prince Philip was the one that demanded she not keep Royal Highness after divorce. Instead of being Her Royal Highness Diana, Princess of Wales, she became Diana, Princess of Wales,” she said.

Prince Charles and Princess Diana tied the knot in 1981 after the former thought that Prince Philip was forcing him to settle down. But what Prince Philip simply wanted was for Prince Charles to not string Princess Diana along if he had no plans of marrying her.
