I do wonder if he even looks at what she posts on Instagram
Just going by photos and video of him , it looks like he is out of it on recreational drugs / medication most of the time, so I would say he doesn’t have a clue nor care what, and if, she posts.
It’s quite interesting they also haven’t posted any Spencer family photos, nor any photos inside Althorp House, just that one leading to Diana’s memorial/ grave. Charles and his recent wives have posted loads from the inside and outside of the house, including entertaining guests there, so it’s not like they are very private about it.
There are a few posts on Charles Instagram where he comments about his childhood home being the one on Sandringham and how that was a very happy family home, clearly the opposite of Althorp. His own experience of Althorp must be very miserable too, so many of his own families have been destroyed in that house, mainly due to his own cheating.
Interesting that Harry aligns himself with Charles Spencer.
