I haven't heard bad things about Clare... on the contrary. However this doesn't surprise me . If it was a factor in her removal, possibly, but I had heard that the merching that Meghan was doing on the back of Givenchy kit was made clear to BP and then by BP to Arnault who saw it as the total opposite of how to PR a luxury brand and Clare got blamed. She fled to hwr country home in Cornwall and basically hasn't worked or even tried to return to London or Paris even though her twins are just under 10, I believe. I don't know if she will ever work again.
None of the other stuff surprises me. I seem to remember seeing a scuffle between the 3 kids that George seemed to be trying to manage as they were walking down the aisle behind the twins.
Also Kate was displaying super protective body language towards charlotte especially after the ceremony.
Also the constant changing of their minds.... sound familiar? The lady who headed the gospel choir that sang Stand By Me said exactly the same thing and that she was totally stressed out. Her words were inches from flat out saying that H&M were a fucking nightmare. I believe this story in full and if a Givenchy employee was slapped by M and it wasn't reported/handled appropriately, then 1) Clare would have 100percent gotten fired for it and 2) see a theme here,,, again? Except here is Maison Givenchy and not BP
