Queen Camilla in a rage: “Shame for father, family and monarchy”. Queen Camilla was apparently very upset about Prince Harry's attitude when he met his father King Charles in London.
After father and son were reunited, she is said to have made clear statements to Harry. This seems to have been the straw that broke the camel's back. A possible explanation for Harry's quick return after only 25 hours in London is that Camilla told him to his face that no one wanted him back.
