Prince Charles got into a "massive fight" with Princess Diana's brother after her death, according to royal commentators. The Prince of Wales' rocky relationship with the Spencer family grew even more tense during planning for the funeral. The List narrator Christine-Marie Liwag Dixon explained what happened between the future king and Earl Charles Spencer.

       She told viewers: "Maintaining a good relationship with the in-laws can be pretty tough.

       "But add a divorce and things can get even worse.

       "Factor in a tragic death, and you've got the perfect storm.

       "According to Page Six, things went downhill for Prince Charles after his divorce from Princess Diana and her untimely death, when it came to his interactions with her family members."

       Ms Liwag Dixon continued: "It was just days after Diana's death when her ex-husband and her brother got into a massive fight over the phone.

       "In his book, 'Battle of Brothers', royal historian Robert Lacey wrote that Diana's brother was in opposition to the idea of Prince William and Prince Harry walking behind their mother's casket at her funeral.

       "Things with the heir to the throne went south quickly.

       "Lacey wrote, 'Spencer felt quite sure that Diana would have been horrified at the idea of her sons having to endure such an ordeal."

       The commentator added: "'He had already told Charles as much'.

       "Apparently, in a conversation with Diana's brother, Charles made 'a particularly offensive comment' about his ex-wife.

       "That all but sealed the ill-fated label on his relationship with the Spencers."

       Her funeral then took place in September that year in London.

       William and Harry did end up walking in the procession behind her coffin.

       Reportedly they were encouraged to do so by Prince Philip who said he would walk with him.
