The private estates of King Charles and Prince Williams generate millions annually in income from public services and charities such as the armed forces, the NHS and state schools, the BBC reported, citing a new documentary by Channel 4’s Dispatches and the Sunday Times.

According to the documentary, King Charles’ private landed property, the Duchy of Lancaster and Prince Williams’ property in Cornwall are part of a deal worth almost £50m (equivalent to ₹543 million).

However, the real estate properties and their transactions “comply with all relevant UK legislation and regulatory standards applicable to its range of business activities”, a spokesman for the Duchy of Lancaster told the BBC.

The six different leases granted by the duchy will generate wealth of around £600,000 over its lifetime.
