The angler who drowned after being swept down the River Spey on Wednesday has been named as retired bio-chemist, Dr Bill Richmond.

The 68-year-old had been wading the river near Advie Bridge during an annual holiday on the Tulchan Estate when he slipped.

Police believe his waders may have filled with water. Despite the efforts of rescuers, Dr Richmond's body was discovered at Blacksboat, more than six miles downstream.

Dr Richmond grew up near Cupar, Fife, and went to St Andrews University. He spent most of his career in hospitals in the London area, and became head of the department of chemical pathology at St Mary's Hospital in the city. He was well-known for inventing the cholesterol test, called the Richmond process.
