Penny Knatchbull’s Love Affair With Prince Philip Was Much Nastier Than You Thought

Penny Knatchbull's Love Affair With Prince Philip Was Much Nastier Than You Thought

LONDON — The most consequential guest at Prince Philip’s funeral was not a Windsor, not a sovereign, and not a blood relative of the man in the coffin. She was a 67-year-old countess whose husband — the grandson of the mentor Philip loved most in the world — was not invited at all.

When COVID restrictions cut the mourners at St. George’s Chapel to just 30 seats in April 2021, every chair became a public statement. The Queen sat alone.

Philip’s German relatives flew in under quarantine exemptions. And near the back of that carefully calibrated arithmetic sat Penelope, Countess Mountbatten of Burma — the only person in the chapel who was not blood, not spouse, and not sovereign.

Buckingham Palace described her as “a close friend of the Duke” and left it there. Fleet Street did the rest. For three decades, the tabloids had a name for her: the Duke’s mistress.

What that name hides is a story far nastier than the 𝒶𝒻𝒻𝒶𝒾𝓇 myth it was built to sell.

The documents that could settle the question were sealed for 90 years. In September 2021, Sir Andrew McFarlane, president of the family division of the High Court, ruled that Philip’s will would remain confidential until 2111. The hearing was held in private.

The press was not told it was happening and had no chance to argue. The Guardian challenged the secrecy. The seal stood.

So the sourcing for the 𝒶𝒻𝒻𝒶𝒾𝓇 story rests almost entirely on people at a distance. Sarah Bradford’s 1996 biography of the Queen stated Philip had affairs, naming Penny among the relationships discussed. Bradford worked from social contacts, not documents.

Other biographers with better access reached the opposite conclusion. Philip himself, asked in 1992 about the rumors, offered a bureaucratic answer rather than a moral one: how could he, when he had had a detective in his company since 1947. He was not claiming virtue.

He was pointing at logistics.

To understand what Penny Knatchbull actually was to Philip, you have to go back to a summer morning in County Sligo in 1979, eight weeks before her wedding, when a bomb in a harbor reduced the family she was about to marry into by four people in half a second.

Penelope Eastwood was born in 1953, and her money did not come from land. It came from steak. Her father, Reginald Eastwood, built the Angus Steakhouse chain — those red-fronted restaurants clustered around London theaters and stations.

It made him seriously rich. It did not make him grand. In Britain in the 1970s, that distinction mattered enormously.

Aristocratic families kept a mental ledger of where money came from, and money from restaurants sat somewhere below money from coal, which sat below money from land, which sat below money that had simply always existed.

She met Norton Knatchbull, Lord Romsey, in the mid-1970s. He was heir to Broadlands, the Hampshire estate, and grandson of Lord Mountbatten — last viceroy of India, first sea lord, and the man who had steered Philip’s entire life, helped engineer his path toward Elizabeth in the 1940s, and lobbied for the family name. Mountbatten was Philip’s uncle, his fixer, his surrogate father.

By 1979, Mountbatten was running one more dynastic project: he wanted his granddaughter Amanda, Norton’s sister, to marry Prince Charles. He had been writing to Charles about it with the persistence of a man who genuinely believed families could be arranged like fleets. Penny Eastwood was walking into a house that functioned as an annex of the monarchy, run by a man who treated matchmaking as strategy.

Then came August 27, 1979. Mountbatten was on holiday at Classiebawn Castle, as he was every summer. That morning he took his wooden boat out from Mullaghmore Harbor to check lobster pots.

The IRA had planted a radio-controlled bomb aboard the night before. It was detonated from the shore.

Mountbatten was killed. So was Nicholas Knatchbull, Norton’s 14-year-old brother. So was Paul Maxwell, a 15-year-old local boy working as a boatman.

Doreen Brabourne, Lady Brabourne, died the following day. Norton’s parents, John and Patricia Brabourne, were pulled from the water with catastrophic injuries. That same day, in a coordinated attack at Warrenpoint, the IRA killed 18 British soldiers — the worst day the British Army had had in Northern Ireland since the conflict began.

The private catastrophe arrived wrapped inside a national one. The family could not grieve quietly even if it had wanted to. Philip’s reaction is documented mainly through absence.

He went silent and kept moving. Charles, who had been closer to Mountbatten than to his own father in some respects, fell apart. Philip organized.

And the wedding stayed on the calendar for eight weeks later.

On October 20, 1979, Penelope Eastwood married Norton Knatchbull at Romsey Abbey. Less than two months after her fiancé’s grandfather and brother had been killed. The Queen came.

Philip came. Prince Charles was best man. Norton’s mother attended with injuries still visible on her face — she had taken well over a hundred stitches.

That wedding was not a celebration. It was a demonstration. The IRA had tried to erase a family, and the family responded by staging the most public, most photographed, most royally attended event it could organize inside the shortest possible time frame, in the same county, in the same church, with the heir to the throne standing at the groom’s shoulder.

It was proof of life conducted as a society wedding. Nobody asked the bride whether she wanted her marriage to serve that function.

From that morning forward, her private life was national property. She had been in the family for about eight weeks and had already learned the operating rule: appearances were not decoration. Appearances were defense.

What happened next is the part the tabloid version never bothers with. Philip, aged 58, took on a role he never formally announced. Mountbatten had been the connective tissue of that family.

That role was now vacant. Philip filled it the way he filled everything — by attaching himself to the practical business of keeping people functional.

He also taught Penny to drive a carriage. Philip had given up polo in 1971 at 50 when his wrist gave out. He needed a competitive outlet, and he chose carriage driving.

He did not take it up as a hobby. He competed for Britain. He sat on the international governing body.

He was personally involved in drafting and revising the FEI rules for the sport. He was, in a literal sense, one of the men who wrote the rule book.

Penny took to it. She became a serious competitor in her own right, driving at Royal Windsor, at Sandringham, at national events for decades. That is not a cover story.

That is a documented sporting career with results, stewards, timekeepers, and photographs.

Consider what carriage driving actually involves: grooms, horses, trailers, a navigator on the back of the carriage, course officials, spectators standing in the mud with cameras. It is one of the least private activities available to a human being. The press decided it was a rendezvous.

That was never really about Penny. Philip had been carrying an 𝒶𝒻𝒻𝒶𝒾𝓇 reputation since the 1950s, long before anyone in Fleet Street knew her name.

Then came October 1991, and the story stopped being about gossip. Leonora Knatchbull was diagnosed with cancer as a small child. She was treated.

She died at five years old at Broadlands. Her parents established the Leonora Children’s Cancer Fund in her memory, and it raised money for children’s oncology for years afterward. Penny worked on it publicly for the rest of her life.

Every biographer who has written about Philip and Penny points to this period as the moment their friendship became something deeper. Philip had a specific competence here, and it is a strange one to admire, but it was real. He was very good with catastrophe.

He had lost his own family to exile, breakdown, and a plane crash. He did not offer comfort in words. He offered structure, activity, and company.

And he kept showing up long after other people had returned to their own lives.

But hold the chronology against the story, because the story is slightly wrong. The friendship did not begin with the child’s death. The carriage driving came first by years.

What the loss did was change the friendship’s weight. It stopped being a shared sport and became the relationship in which she was allowed to be a bereaved mother rather than the wife of an heir.

By then, the couple had another complication. Norton was one of Prince Charles’s closest confidants — part of the small circle Charles leaned on as his own marriage collapsed. Accounts from Diana’s side held that the Romseys had taken Charles’s part.

Penny’s household was inside the Wales war on the Prince’s side, and her husband’s loyalty ran to the future king.

So why not leave? Look at what leaving would have cost in 1993 or 1996. Two surviving children, both still young.

A house that was a public attraction, an exhibition, and a family monument to a murdered man. A title she was still waiting for. A social world in which her only independent standing came from the family she had married into, because the money behind her name came from steakhouses and everybody in that world remembered it.

And a press corps that had already decided she was sleeping with the Duke of Edinburgh. A separation would have been read as confirmation. She would not have escaped the story.

She would have become it.

She stayed. And the genuinely counterintuitive thing is that the family that supposedly should have frozen her out did the opposite. The Queen invited her — not tolerated, invited.

Penny was a regular at Balmoral and Sandringham through the 1990s and 2000s, went to Royal Ascot, joined the royal shooting parties, was on the yacht, was in the photographs. Elizabeth II, a woman with an unmatched instinct for what would look wrong, put this woman inside the family calendar for 30 years.

That is the single strongest piece of evidence against the 𝒶𝒻𝒻𝒶𝒾𝓇 story. And it is also the most ruthless, because the invitations did something else. They made Penny’s position depend entirely on royal favor rather than on her marriage.

Her welcome came from the Queen and the Duke, not from her husband.

Then in 2010, Norton Knatchbull moved out. He was 60. They had been married for 31 years.

The reporting said Norton had left Penny for Jeanie Ferguson, a woman who had been part of the same social circle for years. Neither confirmed anything then or later. There was no divorce.

There was no statement. Several papers subsequently reported a partial reconciliation or at least a return to the same address, and the details vary depending on which reporter you trust. What is solid: in 2010 the marriage was publicly reported to have broken down.

It never legally ended. For the following 15 years, the couple appeared together when the family required it and lived by every credible account largely separate lives.

Look at what that did to her. For 20 years, the press had been running a story in which Penny was the woman who took another woman’s husband. In 2010, her own husband left, and the coverage barely paused.

The headlines that mattered were not about Norton at all. They were about what this meant for her friendship with Prince Philip, who was then 89. She had been recast instantly from wife to available.

The woman labeled a homewrecker had her home wrecked, and the press response was to speculate about her availability to a man in his 90th year.

That is the nastiness the story promises. And it is not sexual. It is that a bereaved mother, publicly abandoned in a house that was a memorial to a bombing, got no version of herself in print except the one that sold.

The Palace’s response is instructive. Nothing changed. She kept the invitations.

In 2011, she was at the wedding of William and Catherine. When her daughter Alexandra married at Romsey Abbey in 2016 — the same church where Penny had married in 1979 — the Queen and Prince Philip both attended. The Queen turning up to your daughter’s wedding six years after your husband moved out is not a social courtesy.

It is a public ruling on which member of that marriage the Crown intended to keep.

Patricia died on June 13, 2017, at 93. After 38 years, Norton became the third Earl Mountbatten of Burma. And Penelope Eastwood of the Angus Steakhouse fortune — the girl whose money came from restaurants — became Penelope, Countess Mountbatten of Burma.

A title created for a viceroy, held by the woman whose husband had left her seven years earlier, and which she now held precisely because she had not divorced him. She had waited 38 years for that position. She took it while living apart from the man who conferred it.

Notice what she did not do. She did not sell a story. She did not authorize a friend to brief a sympathetic columnist.

She did not write a memoir. By 2017, the market for it would have been enormous. She had a genuine grievance, a documented humiliation, and an audience.

She used none of it.

Philip retired from public duties in August 2017, two months after Patricia’s death, and moved his base to Wood Farm on the Sandringham estate — a modest house, five bedrooms, no staff to speak of by royal standards. He spent his last years there reading, painting, and receiving a very short list of visitors. The Queen came at weekends.

His children came. And Penny came repeatedly over the four years he had left. They were still photographed driving a carriage together at Sandringham when he was in his late 90s.

Those pictures were taken by long lens, sold, and captioned as a romance. What they actually show is a 97-year-old man who could no longer walk far, out in a carriage with the person he had taught the sport to 35 years earlier, near the end of his life.

He died on April 9, 2021, aged 99. And then came the funeral and the 30 chairs.

Norton Knatchbull, third Earl Mountbatten of Burma, grandson of the man who had shaped Philip’s entire career, was not there. His wife was the sole guest at that funeral who was not a member of the royal family or a Windsor relation. Whether Norton was excluded, declined, or simply lost the arithmetic of 30 seats has never been explained by anyone with authority to explain it.

What the guest list did is not in dispute. It made a public statement, in the most watched televised event of that year, about which of those two people Philip had counted as family.

Five months later, the last door closed. Every document Philip might have left concerning his affairs, his bequests, his acknowledgements is locked until 2111. The Royal Archives at Windsor operate on access granted at the Crown’s discretion.

Penny has never given an interview about him, and there is no indication she ever will.

In 2022, the fifth season of The Crown dramatized the friendship, with Natascha McElhone playing Penny and the carriage driving used as the central image of an emotional attachment. Reports at the time said the family found it distressing. It does not matter now.

That is the version that reached a hundred million people, and it will outlive everyone who could correct it, because the correcting material is under seal until 2111.

Norton died in 2025. Penny outlived him. Still Countess Mountbatten of Burma.

Still silent.

Go back to the chapel and the 30 chairs. The reason the myth was persuasive is that it required no work. A rich man’s reputation, a beautiful woman 32 years younger, a shared sport nobody outside it understood, and photographs taken from 400 yards away.

It gave people a story with a shape.

What it excluded was everything that actually happened to her. A wedding held eight weeks after a bombing because a wounded family needed to be photographed surviving. Thirty-eight years as the wife of the heir in someone else’s title.

A five-year-old daughter buried at Broadlands. A husband who left in the full glare of the papers that had spent 20 years calling her someone else’s mistress. And a friendship with an old man who had lost his own family young and was better at standing beside catastrophe than at almost anything else.

She was never really one of them. The money was wrong, the name was wrong, and there was always someone senior holding the title. What she had instead was the skill people noticed in her at 23 and mistook for coldness.

She watched, she measured the room, and she said nothing.

It cost her four decades of her reputation. It also won her the last argument. Every person who wrote about that friendship had to guess.

And she never once gave them anything to work with.

Thirty chairs at Windsor. She sat in one of them, in public, on camera, and gave the world exactly what she had given it since 1979. Nothing.
