I found this today by accident.
Interesting, but of course how would they know?
For the record and for whatever it's worth...
Queen Elizabeth the Queen Mother 1900-2002: The Legacy: Charles to | Sunday Mirror Newspaper | Find Articles at BNET
The Queen Mother was worth an estimated £60 million - making her the third richest member of the Royal Family behind the Queen and Prince Charles.
The lion's share of the Queen Mother's wealth will go to her great-grandchildren.
Prince William and Prince Harry will receive nearly £2.5 million each when they reach 21.
They will each get a further £8 million when they reach 40.
Zara and Peter Phillips and Princesses Beatrice and Eugenie will share £6.1 million.
The children of Lady Sarah Chatto and her brother Viscount Linley will also benefit.
. . . . . .
A couple of obvious points...
The Queen Mother may have left an estate worth £60m (US$90m) but she didn't leave this amount in cash. Most of the assets (which were non-income-producing such as jewels, paintings and objet d'art) would have passed directly to the Queen in the traditional Sovereign-to-Sovereign transfer. The cash amounts listed above total over £27m (US$40m). Would conservatively-managed trust funds generate this sort of return?
Viscount Linley and Lady Sarah don't get a mention, although their children do. While they would be the beneficiaries of their mother's estate (the bulk of which I assume to be in the form of fixed assets rather than cash), how likely is it that the Queen Mother would not have made direct provision for them or have set up trust funds in their names?
