Princess Diana's older sister Lady Sarah McCorquodale was depicted in season four of The Crown, but where is she now?
Lady Sarah Spencer, as she was known before her marriage to Neil McCorquodale, dated Prince Charles briefly and was the one who introduced him to her younger sister.
She and her family reside near Grantham, Lincolnshire, and she has largely stayed out of the public eye since her sister Diana's tragic death in 1997.

However, she and Diana's other sister, Lady Jane Fellowes, have remained close with their nephews Prince William and Prince Harry.
Lady Sarah and Lady Jane both attended the Duke and Duchess of Sussex's son Archie's christening in Windsor in 2019 and were pictured in the official family portraits.
