But a series of royal scandals, and the arrival of a new slimmer outlook for the future Royal Family, may have contributed to why Beatrice and Eugenie are non-working royals now.
The royal historian explained: “This has been my view for many, many years. I think if there were no scandals in the 1990s, Charles and Diana, Andrew and Sarah, and to a lesser extent Anne and Mark.”
She added: “It is possible that say Andrew and Sarah had remained a happily married couple, I do think those girls would be working royals.
“Back in the late 1990s, there was a group called the Way Ahead group. It included senior royals, advisors and I believe some government officials, and it was already discussed that the Royal Family would be slimmed down.”
