A complaint about The Money Programme: Diana's Lost Millions has been partly upheld by the BBC's Editorial Complaints Unit.
The show looked at claims charities had been hit by a cash freeze
The programme investigated criticisms that the Diana, Princess of Wales Memorial Fund had wasted millions of pounds on a protracted legal battle with The Franklin Mint.
Despite signing licensing deals with other companies, the Fund refused the American doll makers an official license for their Diana dolls and plates.
The Diana Memorial Fund complained that Diana's Lost Millions, broadcast last May, was unfair and misleading.
The Editorial Complaints Unit, which investigates complaints independently of programme makers, has upheld aspects of the complaint.
Firstly, the Fund should have been given an opportunity to respond to the allegation by a representative of the Mines Advisory Group that lives had been lost as a result of the freezing of the Fund's grant during the legal action.
Secondly, the it was misleading to use the inaccurate term "damages" in describing what was an out-of-court settlement with the Franklin Mint.
