The guest list for Prince Philip’s funeral on April 17, 2021, was limited to just 30 people due to pandemic restrictions. Nearly every name belonged to the immediate royal family, their spouses, or members of the Duke of Edinburgh’s scattered German relatives. The thirtieth guest, however, was neither blood nor marriage. Her name was Penelope Knatchbull, and for nearly 30 years she had been Prince Philip’s closest companion outside his marriage.
Penny Knatchbull was born Penelope Eastwood in London in 1953. Her father, Reginald Eastwood, had started his working life as a butcher’s apprentice at 15 before building a fortune through a chain of London steak houses that reportedly turned over around £20 million a year at its peak. She was educated in Switzerland and graduated from the London School of Economics in 1976. Her background was wealthy, but it was not aristocratic.
She first met the Queen and Prince Philip in the mid-1970s through the rural world of horses and country weekends. Philip was 32 years her senior. Their acquaintance continued quietly until she married into the extended royal circle in the autumn of 1979. That marriage came just eight weeks after one of the darkest days in the family’s history.
On August 27, 1979, the IRA assassinated Lord Louis Mountbatten, Prince Philip’s uncle and a father figure to him. A bomb hidden on his fishing boat killed Mountbatten, his 14-year-old grandson Nicholas Knatchbull, a 15-year-old local boy, and Mountbatten’s 83-year-old sister-in-law. Eighteen British soldiers were also killed that same day in a separate ambush. Penny married Nicholas’s brother Norton Knatchbull, Lord Romsey, on October 20, 1979, entering a family still raw with grief.
The friendship between Penny and Prince Philip deepened after personal tragedy struck her own family. In the autumn of 1991, her five-year-old daughter Leonora died of kidney cancer. Penny insisted on burying the child in the grounds of Broadlands, the family estate, so she could always be near her. Royal biographer Ingrid Seward records that Philip befriended Penny as her life was falling apart, encouraging her to take up carriage driving as a way to cope.
The shared experience of loss became the foundation of their bond. Carriage driving became the public arena for their friendship. Philip had taken up the demanding equestrian sport in 1971 after retiring from polo, and he drew Penny into it after 1991. They appeared together year after year at the Royal Windsor Horse Show, in full view of crowds and cameras.
Philip also encouraged his daughter-in-law Sophie and his granddaughter Lady Louise Windsor into the sport, making it a family discipline rather than a private language between two people. Seward, who studied Philip’s life for decades, described Penny as the second most important woman in his life, not a mistress but his “confidante, loyal friend, and keeper of secrets. ” According to Seward, the Queen was confident nothing improper occurred and viewed the relationship as almost complementary to the marriage. The Queen kept Penny close for four decades, including at the end: when pandemic rules forced the funeral guest list to just 30 people, the Queen personally included Penny, who attended partly as a representative for her husband Norton, then too ill to be present.
Over the years, tabloid speculation repeatedly hinted at an affair, but no credible evidence ever emerged. The press ran stories built on photographs and innuendo rather than facts. In 2022, the popular drama “The Crown” dramatized the friendship, inventing scenes and dialogue between the two real people, one of whom had just died and the other who has never spoken publicly about the relationship. Jonathan Pryce, who played Philip in the series, distanced himself from the romantic interpretation in interviews, saying the relationship was “not as people think.
”
Penny herself has maintained complete silence on the subject for more than 40 years. She has never given an interview, never denied a claim, and never corrected a rumor. After Philip’s death, she attended the Queen’s funeral in September 2022 and has continued her quiet public duties, including serving as High Steward of Romsey. The children’s cancer charity she founded in memory of Leonora continues its work under the name of the Edwina Mountbatten and Leonora Children’s Foundation.
The evidence presented across decades of biographies and court reporting points to a deep and loyal friendship born of shared grief, conducted openly, and blessed by the Queen herself. The thirtieth seat at the funeral was not, according to the consistent testimony of those who studied the royal family closely, a scandal revealed at the last moment. It was the final public acknowledgment of a bond that had sustained a grieving woman and a lonely prince for nearly half a century.
