" Although she has a tendency to be overly impressed by those with academic qualifications, Diana admires people who perform rather than pontificate. Richard Branson, the head of Virgin airlines, Baron Jacob Rothschild, the millionaire banker who restored Spencer House, and her cousin Viscount David Linley who runs a successful furniture and catering business, are high on her list. “She likes the fact that David has been able to break out of the royal mould and do something positive,” says a friend. “She envies too his good fortune in being able to walk down a street without a detective.”
For years her low intellectual self-esteem manifested itself in instinctive deference towards the judgments of her husband and senior courtiers. Now that she is clearer herself about her direction, she is prepared to argue about policy in a way that would have been unthinkable several years ago. The results are tangible. Foreign Office diplomats, notoriously hidebound in their perceptions, are beginning to realize her true worth. They were impressed by the way she handled her first solo visit to Pakistan and subsequently discussed trips to Egypt and Iran, the Islamic republic where the Union Jack was routinely burned until a few years ago. This is, as she would say, a “very grown-up” part of her royal life. "
