Carole and Michael Middleton, the parents of Kate and Pippa Middleton, have continued to maintain a private life, and specific details about their personal lives after their daughters' marriages have not been widely publicized. Therefore, any information regarding their activities or experiences beyond that date would require more recent updates from reliable news sources.
Before 2021, Carole and Michael Middleton were known for their involvement in their family's business, Party Pieces, which is a successful party supplies company. They have also been actively supportive of their daughters, particularly in their royal roles. Carole Middleton, in particular, has been praised for her poise and support during Kate's transition to becoming the Duchess of Cambridge after her marriage to Prince William in 2011.
It is not uncommon for the parents of public figures, especially those with connections to the British royal family, to maintain a low profile to respect their privacy. As a result, there may not be extensive public information about their lives after their daughters' marriages.
