Sir David Frost’s son Miles has died aged 31.
The businessman – who was a founding partner of private equity group Frost Brooks – reportedly collapsed while jogging near his family home in Oxfordshire on Sunday (19.07.15) leaving behind shocked friends and family who said there were "no signs that anything was wrong".
Family friend Lord Chadlington said: "Miles was a wonderful eldest son who was very well loved by all his friends and family.
"This is a terrible shock. I had breakfast with him last Thursday and he was in great form. There was no signs that anything was wrong. It just underscores the fragility of life."
The news comes just two years after his broadcasting legend father – who presented current affairs shows including ‘The Frost Report’ and ‘Breakfast with Frost’ for more than four decades – died of a heart attack aged 74 while on board the MS Queen Elizabeth cruise ship.
A post mortem examination is now set to take place on Miles – who is survived by his mother Lady Carina Fitzalan-Howard and brothers Wilfred, 29, and George, 28 – following his sudden collapse.
Lord Chadlington told the Daily Mail newspaper: "There will be a post mortem examination but all we know is that he collapsed while jogging.
"The Frost family are extremely close and they will all miss him terribly, as we all will. It is hard to lose a loved one at any age, but 31 really is difficult to comprehend."
Another friend paid tribute to the keen athlete – who had previously run a half marathon in the Lewa Game Reserve in Kenya – describing his death as "a terrible shock".
He added: "Miles was in great form recently and seemed really fit and well. It’s a terrible shock and everybody feels desperately sorry for his mother and brothers. He was a wonderful man who has gone far too early."
