The survey includes valuations of the Crown Estate and Duchy of Cornwall.
"These simply cannot be counted as personal assets," said a palace spokeswoman. "The Royal Family gains no personal benefit from the Crown Estate whatsoever and to include it in the calculation is misleading. Also, although the Prince of Wales is entitled to revenues from the Duchy of Cornwall, he cannot sell its assets." The magazine lists the Windsors' assets as:
Cash and investments - pounds 520m;
Art collection - pounds 1bn;
Jewellery - pounds 130m;
Crown Estate - pounds 700m;
Duchy of Cornwall - pounds 195m;
Other property or assets - pounds 160m.
