Duns businessman Charles Letts, the last remaining family member of the diary dynasty still working for the Dalkeith-based company, has died suddenly at the age of 49.
Mr Letts, the sales director for the FLB Group, was found lying in the driveway of his home in Duns after returning from a run.
A former tank commander in the army, he was described as an active sportsman who played polo, tennis, cricket and was also a skier.
He was married to Rosie with whom he has three children, Emily, 14, Harry, 13, and Louisa,11.
“It has hit us like a sledgehammer. He was a very fit guy,” said Gordon Presly, chief executive of the company who had worked with Mr Letts for 18 years.
The pair were involved in two management buyouts in 2000 and 2006. In 2001 they acquired Filofax which became famous in the pre-smartphone 1980s as the must-have personal organiser.
Mr Presly said in a statement: “It is with an unfathomable level of sorrow and sadness that I have to inform you of the sudden death of Charles Letts.
“This whole situation is almost too tragic and heartbreaking to try and put into words.
Charles was an immensely popular and likeable individual with many close friends and acquaintances. He will be hugely missed by his family, his friends and his work related associates.
“Our deepest sympathy and sincere condolences go to Charles’ family who, as you would expect, are utterly devastated and numbed by his sudden and unexpected passing.
“I would also ask that their privacy is respected at this hugely sensitive time.”
Mr Letts joined the family firm in 1990 at the age of 25.
He grew up in North Northumberland, first at Kilham in the Bowmont Valley, and then at Hethpool in the College Valley,
In recent years his home has been at Polwarth Manse, near Duns in Berwickshire.
