The King has raised millions of pounds for charity thanks to profits from his Duchy Originals range, with his branded biscuits, beer, herbal medicine and garden tools helping him earn a fortune.
King Charles set up the company based at his Highgrove House estate, Tetbury in 1990 and it has since become established as a leading organic and natural food brand, and in 2010 went into partnership with Waitrose.
The retailer sells a full range of products under the now renamed Duchy Organics brand, including meat, fish, eggs and dairy. It also sells the well-known Duchy Originals biscuits, which is arguably the range's biggest success.
