When I Google Duchess of York and de Ferranti, I'm directed to this Times page that no longer exists!
http://www.thetimes.co.uk/tto/life/courtsocial/article4675731.ece If I look at the cached version, though, I can see the same version of the Court Circular that was posted here.
What does this mean? Along with Joe Little's tweet being apparently deleted, it seems like Sarah's name wasn't meant to be in the Court Circular in the first place. But then how did it get there?
(I'm also surprised that Sarah made it to the Court Circular. Secretly she must be pleased...it must have been years, maybe since her divorce, that she was listed there.)
