That's a nice video they put out. Is it official is Kate the new "tennis lady" like the Duchess of Kent used to be? I'm probably late to this news.
Kate’s been Parton of both All England Lawn Tennis and Croquet Club and Lawn Tennis Association since January 2017. Before then The Queen was patron and only made a handful of appearances at Wimbledon throughout her reign.
The Duke of Kent has been President of All England Lawn Tennis and Croquet Club since 1969 so using The Duchess as the “tennis lady” was the obvious choice. Looks like Kate has taken over which does make sense given her patronages, interest in tennis, age, and The Duchess of Kent’s desire to maintain a very low profile.
