There was an agreement.
The House of Windsor reneged.
As for whether or not the Queen signed off on it, who the heck knows.
Even if she did, the promise was still broken.
Great way to start off your reign, Chuck, with a lie.
Several people on an earlier thread already told you that the Queen made the decision and announced it earlier this year as part of her Platinum Jubilee that she wanted Camilla to be called “Queen Consort.” It’s not a lie.
