According to sources, on the night of the Queen’s 94th birthday, she allowed the staff to have champagne with their supper.
Some members of the team suggested standing for a toast, while others felt it was unnecessary and could be done sitting down given the intimate gathering, the MailOnline reported.
At this point, Ms Kelly reportedly stormed out of the room in frustration.
However, despite this, it appears that Angela’s biggest misstep was falling out with the Queen’s family.
