I want to know the answer to the following question:
In 1991 what money issue of the Queen was a feature of public criticism?
All the background I'm provided with is that "By the start of 1991, republican feeling in Britain had risen because of press estimates of the Queen's private wealth—which were contradicted by the Palace—and reports of affairs and strained marriages among her extended family.". Is that enough to answer the question?
Answer: yes
