Harry & Meghan’s UK Return Faces a New Complication as Earl Spencer Prepares to Revisit Diana’s Final Days

Prince Harry and Meghan Markle’s planned return to Britain could be overshadowed by a deeply personal new chapter in the story of Princess Diana — one written by Harry’s uncle, Earl Spencer.

The Duke and Duchess of Sussex are expected to return to the UK later this month with their children, Prince Archie, seven, and Princess Lilibet, five. The family is understood to be planning to live in a private, non-royal residence rather than returning to royal life.

But as Harry prepares to rebuild a life in Britain, his uncle Charles Spencer is preparing to publish Swan Song: Diana, My Sister, a personal account of his sister’s life and the events surrounding her death.

The book is scheduled for publication on September 22, 2026 — only weeks after the Sussexes’ return. Spencer has described the project as his own perspective on Diana’s life and the tragic period surrounding her death.

A difficult coincidence for Harry’s return

The timing could prove particularly sensitive.

Harry and Meghan spent time at Althorp, the Spencer family estate in Northamptonshire where Diana is buried, during their UK visit in July. The estate has long held a special significance for Harry because of his connection to his late mother.

There has also been speculation that Althorp could provide temporary accommodation for the Sussexes while they wait to move into their permanent UK home.

Royal biographer Ingrid Seward has argued that such an arrangement would make sense, pointing to the longstanding relationship between Harry and his mother’s family.

Charles Spencer and his sisters have remained part of Harry’s wider family network, with Spencer appearing alongside his nephew at significant occasions in recent years.

The planned book, however, introduces another layer to that relationship.

Spencer’s account of Diana is expected to revisit painful royal history

Swan Song: Diana, My Sister will offer Charles Spencer’s perspective on Diana’s life, including the traumatic final period before and after her death in Paris in August 1997.

Spencer was famously outspoken at Diana’s funeral at Westminster Abbey on September 6, 1997.

His eulogy contained pointed criticism of the royal establishment and the way Diana had been treated following her divorce from the then Prince Charles.

One of the most controversial issues surrounding the funeral was the decision for the young Prince William and Prince Harry to walk behind their mother’s coffin.

Spencer has previously spoken about how deeply disturbing that experience was for him.

In 2017, he described walking behind Diana’s coffin with the two grieving boys as the worst part of the day. He also said he continued to have nightmares about the experience.

Harry himself has since questioned the decision.

In his 2023 memoir Spare, he recalled feeling numb during the procession, while previously saying he did not believe any child should have been expected to take part in such a moment.

A royal family already dealing with Harry’s return

The publication comes at a particularly sensitive time for the Windsors.

Harry and Meghan left their roles as working royals in 2020 and moved to California. Their departure was followed by years of public disputes, including Harry’s interviews, the couple’s Netflix documentary and Harry’s memoir.

Now, six years later, the Sussexes are preparing to spend an extended period back in Britain.

There are currently no public plans for Harry or Meghan to resume royal duties. Their children are expected to attend school in the UK from September, while the couple will continue their private business interests.

The return has nevertheless created the possibility of greater contact between Harry and his family.

Harry and Meghan met King Charles and Queen Camilla privately at Highgrove in July, a reunion that marked an important moment after years of strained relations.

Whether that progress can continue remains uncertain.

Why Althorp matters so much

For Harry, Althorp represents something very different from the royal residences associated with his childhood.

It is the ancestral home of the Spencer family and the place where Diana is buried.

Seward has described the estate as a sanctuary connected directly to Harry’s memories of his mother.

The relationship between the Spencers and the Windsors also stretches back generations.

Diana’s family has long been closely connected to the Royal Family. Spencer’s father, Johnnie Spencer, served as an equerry to both King George VI and Queen Elizabeth II, while other members of the family also maintained links to the monarchy.

But the Spencers have historically been less reluctant than the Windsors to confront uncomfortable subjects publicly.

That difference is particularly relevant now.

The Royal Family has traditionally been associated with the principle of “never complain, never explain”. Spencer, by contrast, has previously spoken openly about matters he believed required an answer.

His disputes with the BBC over Martin Bashir and his earlier memoir about his own childhood are examples of his willingness to confront difficult subjects.

What Spencer says about the new book

Spencer has explained that repeated requests for interviews surrounding the anniversary of Diana’s death persuaded him to finally record his own memories.

Rather than allowing others to tell Diana’s story, he said he wanted to put down his own recollections and correct what he considers inaccuracies.

The book is not being presented as a royal family exposé. Publisher information describes it as an intimate account of Diana’s life told from the perspective of her brother, including the circumstances surrounding the final week of her life.

The publication is also arriving as the world approaches the 30th anniversary of Diana’s death on August 31.

That timing guarantees renewed attention on one of the most painful chapters in the history of the modern Royal Family.

Harry’s connection to Diana remains central

Diana’s memory has remained an important part of Harry’s public life.

He has repeatedly spoken about his mother and the impact of losing her at such a young age. His own memoir also revisited the events surrounding her death and his childhood.

A documentary project involving Harry and connected to the anniversary of Diana’s death has also reportedly been in development, potentially bringing further attention to the Spencer family’s role in preserving Diana’s legacy.

That makes the publication of Spencer’s book especially significant.

Harry may be returning to Britain at a moment when his family relationships are beginning to show signs of movement — but the story of his mother is about to be placed under an intensely personal spotlight once again.

And if Harry and Meghan do spend time at Althorp, they could find themselves at the centre of that conversation just as Spencer’s version of Diana’s story reaches the public.

For now, the Sussexes’ return is being presented as a move back to Britain for family and practical reasons, rather than a return to royal duties.

But with Swan Song: Diana, My Sister arriving on September 22, the timing could make Harry’s homecoming far more emotionally complicated than a simple return to the country he left six years ago.
