Royal aides said Prince Charles was keen to take over the work of the late Queen Mother, who had links with everything from cattle associations to cancer charities. He is taking over the patronage of 21 charities, including the Salmon and Trout Association.

It was his grandmother, who had a passion for angling, who first taught him to flyfish for trout and salmon.

Other groups include the Chelsea Physic Garden, The Garden Society, The Society for the Protection of Ancient Buildings, The National Trust, the Royal Scottish Society of Painters in Water Colours and the Aberdeen Angus Cattle Society.
