[quote derxa]This talk of stripping of titles seems very mean spirited and it won't happen. Hereditary titles remain whether the person is a scoundrel or not. Should we strip Lady Sarah Chatto of her title. She doesn't do any royal duties. I looked up her Wiki page and her life sounds like an EM Forster novel. en.wikipedia.org/wiki/Lady_Sarah_Chatto[/quote]
Even I’m not advocating stripping the titles they get at birth, and I seem to be the sans culottes revolutionary of the thread. 
Lady Sarah Chatto has held that title since birth, it’s her name, fine let her keep it.
Prince Harry has been Prince Harry (Henry) since birth. Ditto, it’s his name, he should keep his name.
Prince Andrew is as born Prince Andrew. That’s his name, ditto.
What I do think should be removed from non-working royals are the extra titles that they are given in adulthood, and given in the expectation that they will be working royals.
Two different things entirely.
