Queen Camilla was allegedly confronted by Princess Anne over her new title at a tense Coronation dinner with other members of the Royal Family.
The Princess Royal is alleged to have told her sister-in-law that her title is Queen Consort and not Queen, according to Princess Diana's dressmaker, David Emanuel.
He claimed that the topic of Camilla's new title is "highly charged" and that "a lot of people" are "unhappy" that she will be referred to as Queen rather than Queen Consort.
