Princess Diana’s death was one of the saddest times in recent history. The Princess of Wales, who was dubbed as the ‘People’s Princess,’ was so loved around the globe that everyone mourned on her death.

Robert Lacey, a famous royal history, recounts a time when Prince Charles made some offensive comment days after Diana’s death that led Diana’s brother to slam the phone on the Prince.

According to his explosive new memoir of the royal family, Prince Charles was said to have phoned Diana’s younger brother, Earl Charles Spencer, after the royal family had already been in a heated discussion on Prince William and Prince Harry’s role in Diana’s funeral.

There was a point when Prince Charles was said to have commented on Princess Diana’s death that truly enraged and offended Earl Spencer.

From then on, the Mountbatten-Windsor family and Diana’s own aristocratic family had bitter relations with each other.

The particular event of Diana’s procession, which happened six days after her passing, was something the Spencer family did not want to become a royal occasion.

The family who wanted it to be intimate between the two families was turned by the royal firm into a media frenzy.

Added to the fact that both Prince William and Prince Harry were forced to walk behind their dead mother's casket for over a mile.

The royal princes were joined by their father, Prince Charles, who urged them to walk behind and their grandfather, Prince Philip, The Duke of Edinburgh.

20 years after the death of their mother, Prince Harry reveals his opinion on the occasion.

Prince Harry shared his thoughts on how he never wanted to walk behind his mother's casket during the procession and that it affected him negatively for the rest of his life.

He then continued on saying that no one should ever do that, pointing out that it would not have been allowed nowadays in the royal family.

Prince Charles's bitter marriage to Princess Diana was already a major problem for the royal family as well as the Spencer family.

Earl Charles Spencer, during his eulogy to the late Princess Diana, made sure to take a subtle swipe at the royal firm.

In his speech, he said, we, your blood family, will do all we can to continue the imaginative, loving way in which you were steering these two exceptional young men so that their souls are not simply immersed by duty and tradition but can sing openly as you planned.”
