The eldest son of broadcaster David Frost has died at the age of 31 while out jogging, a family friend has said.

Miles Frost, a founding partner of the private equity group Frost-Brooks, collapsed during a run near the family’s home in Oxfordshire on Sunday, according to Lord Chadlington .

Frost, the eldest son of Sir David and Lady Carina Fitzalan-Howard, was a fitness enthusiast who had previously run a half-marathon in the Lewa game reserve in Kenya, regarded as one of the hardest long-distance challenges due to the heat and high altitude.

Confirming his death, the Frost family paid tribute to Miles, calling him a “wise and loyal” son and brother.

His mother, Lady Carina Fitzalan-Howard, said: “Miles quite simply was born an old soul. And everybody was drawn to his wisdom, love, loyalty and laughter.”

Frost’s two younger brothers, TV presenter Wilfred, 29,and drinks entrepreneur George, 28, said: “Miles was the kindest and most generous brother we could have wished for. Since dad died he was the leader of our pack.

“Everyone who Miles met immediately fell in love with his warmth, selflessness and incredible sense of humour. He has gone far too soon and is so undeserving of this.”

Chadlington, who invested in some of the same businesses as Frost, said: “He was a great guy. He is a very fine man. David and Carina put the children at the heart of everything they did. It’s a terrible loss. I knew him very well. He was very hard-working, very intelligent, very kind. Extremely moral in his judgment.”

Chadlington, who is president of David Cameron’s Witney Conservative constituency association, said Frost went for a jog on Sunday afternoon and “didn’t return for a long time”. By the time he was found, he had died.

“It was a a huge shock to the family,” he said. “He was an actively healthy person. I didn’t think he overdid it. He always had a plan to do something new. He was very careful about his diet and didn’t drink alcohol. He was studious.”

Frost’s death comes just two years after his father died aged 74 after suffering a heart attack on the Queen Elizabeth cruise ship.



Frost and his two younger brothers all attended Eton. Before founding Frost-Brooks, Frost spent five years at another private equity firm, LDC, working on technology, media and telecoms investments. His company website says his personal network “includes some of the most respected names in business and media”, many of whom have invested with Frost-Brooks.

He was also a board member of David Paradine Productions, his father’s TV production company, the website says, as well as BizEquity, which enables business owners to gain an online value of their company, and the delivery firm Parcel Monkey.

Last year, Frost, his brothers and their mother, were joined by 2,000 guests, including the Prince of Wales, for a memorial service for their father at Westminster Abbey.

David Frost was a TV star for more than 50 years and was known for his incisive interviews – most famously with the disgraced US president Richard Nixon.
