Former Standard Life chief executive Sir Sandy Crombie said: “My main memory of the Queen was when she came for the official opening of Standard Life’s new offices in Tanfield in Edinburgh in 1992.

“Her expression, and I guess her mood, seemed to change dramatically for the better when she was presented with a bouquet of flowers, along with the explanation that the flowers had been chosen to represent the various countries in which Standard Life did business - Scotland, England, Ireland, Wales and Canada. It was a small thing, but she was animated in conversation and obviously appreciated it.”
