Promoting the new royal documentary on ITV titled, Prince Charles: Inside The Duchy of Cornwall, Prince Charles and Camilla Parker Bowles wrote on Instagram: "The new two-part documentary follows staff and tenants of the Duchy of Cornwall during The Prince of Wales’s 50th working year as The Duke of Cornwall."
According to the synopsis, the documentary will follow the Duchy of Cornwall throughout one year.
"When Prince Charles took over the running of the Duchy 50 years ago, it was barely breaking even; today, it’s worth nearly £1bn, generating a profit of £21m a year to support not only his own household with Camilla but also those of William and Catherine, Harry and Meghan and the princes’ grandchildren, as well as funding charitable work," the website reads.
Prince Charles has four grandchildren, the children of Kate Middleton and Prince William - Prince George, 6, Princess Charlotte, 4, and Prince Louis 1 - and the son of Prince Harry and the Duchess of Sussex, Archie Harrison, 5 months.
