The eldest son of Sir David Frost has died aged 31 while out jogging near his home.

The financier collapsed during a run at the family’s holiday home in Oxfordshire on Sunday.

Family friend Lord Chadlington told the the Daily Mail that Miles had showed no signs of any health problems.

Mr Frost had two younger brothers - Wilfred, 29, a TV presenter on financial channel CNBC, and George, 28.

Miles was a running enthusiast and had taken part in a tough half marathon in the Lewa Game Reserve in Kenya, thought to be one of the most gruelling because of the altitude and heat.
