Prince Harry and Prince William maintain distance at uncle's funeral amid ongoing royal family conflict, according to a report.

The feud between Prince Harry and Prince William appeared to have caused them to avoid each other at a family event.

On Thursday, both Harry, 39, and William, 42, attended a memorial service for their mother's brother-in-law, Lord Robert Fellowes, as reported by the BBC.

The Duke of Sussex left his residence in Montecito, California, to attend St. Mary's Church in Snettisham, England, with his family, including the Prince of Wales.

The memorial service for Fellowes took place near the royal Sandringham Estate in Norfolk.

A source who was present at the service confirmed that both Harry and William were there, according to the BBC.

An anonymous church warden shared with the BBC that it was wonderful that both princes were able to attend their uncle's memorial service yesterday at St. Mary's Church.

"The occasion was a family celebration of a special man's life, attended by many friends and members of the St. Mary's Church family."

The princes attended the funeral "discreetly," as reported by The Sun.

Kensington Palace did not respond to Planet Chronicle Digital's inquiry about the matter.

Harry's not-for-profit organization, Archewell, did not promptly respond to Planet Chronicle Digital's inquiry for comment.

For over four decades, Lord Fellowes was married to Lady Jane Spencer, the late Princess Diana's sister. They had three children together and were uncles to Harry and William.

Ronald Ferguson, the father of Prince Andrew's former wife Sarah Ferguson, Duchess of York, was also his cousin, as per the BBC.

Between 1977 and 1999, Lord Fellowes served in the private office of Queen Elizabeth II, and during the 1990s, he held the position of her private secretary, which was the highest-ranking official in the monarch's household.

Prince Harry steered clear of another confrontation with his brother during the summer.

In June, the Duke of Westminster and Olivia Henson got married at Chester Cathedral in northern England, and while the Duke of Sussex was invited, Harry declined to attend to avoid an "awkward" encounter with William.

According to Christopher Andersen, author of "The King," if Harry attended the wedding and sat in the back row, the media coverage and excitement surrounding the two brothers being in the same room would outshine the wedding itself, as reported by Planet Chronicle Digital.

In February, King Charles III was visited by his son Harry in the U.K., following the monarch's cancer diagnosis.

At the time, Hilary Fordwich, a royal commentator, told Planet Chronicle Digital that Harry was reportedly not permitted to stay at any royal homes and did not have a reunion with William.

The royal exit of Harry and Meghan Markle in 2020 has caused a rift between the brothers.

The reason for the couple's departure was due to the unbearable intrusions and racist attitudes of the British media, as they described it.
