DARTMOOR Charles owns great tracts of Dartmoor and is paid rent by farmer tenants. The Duchy also owns Dartmoor prison, for which the government pays rent. ART COLLECTION Many pieces of fine art and furniture that adorn the walls and palatial rooms of Highgrove are personally owned by Charles. GIFTS Prince Charles has received gifts worth £20m, many from his two weddings Some of these were passed on to his staff who sold them on Control is now tighter. Nevertheless, the estate owns The Oval, above, run by Surrey County Cricket Club, which used to be charged £10 a year to use the ground The SCCC pays much more now.

THE KENNINGTON ESTATE The Duchy owns several inner-London properties south of the Thames, but some of the best bits, such as a stretch of river-front by the South Bank Centre, were sold in the 1950s. But many tenants are expected to pay a fair rent, and some are aggrieved by the Duchy’s decision to enter their holiday-home business. The Duchy has renovated a two-bedroom home traditionally used by teachers on St Mary’s. Scillonians say their needs have been put second to add to the £13m-a-year Duchy profits. DUCHY ENTERPRISES The Duchy Nursery, which sells a range of exotic plants, and Duchy Originals, the company supplying premium-priced organic biscuits, jams and sausages, is valued at £463m The profits go to the Prince’s charities.

THE ISLES OF SCILLY Since 1986, the Duchy has accepted a single daffodil as rent from the Isles of Scilly Environmental Trust, which leases all the uncultivated land and uninhabited off-islands. POUNDBURY The model village outside Dorchester in Dorset, conceived by Prince Charles, is an experiment using traditional architectural styles and local materials. There is nothing old-fashioned about the cost of living in Poundbury. Prices of the 300 properties in the village vary from £230,000 to £425,000, above the norm for this part of Dorset. In the first phase of development, 20 per cent of homes were classed as affordable and made available for rent through the Guinness Trust housing association. Critics say only someone as well off as the Prince of Wales could finance such idealistic projects which makes them an unrealistic template for mainstream developments.
