Lacey also claims that William “came to find consolation in the idea that he would one day be ‘king’” as his parents’ fighting “intensified.”
Additionally, Prince Harry allegedly declared, “I can do what I want,” at four-years-old during an argument with his older brother as the Duke of Sussex invoked the line of succession.
Appearing in a 1995 BBC Panorama interview, Diana opened up about how she explained her divorce from Charles to their sons.
"William asked me what had been going on, and could I answer his questions, which I did," she admitted.
"He said, 'Was that the reason why our marriage had broken up?' And I said, 'Well, there were three of us in this marriage, and the pressures of the media was another factor, so the two together were very difficult.' But although I still loved Papa, I couldn't live under the same roof as him, and likewise with him."
Diana also revealed that she offered William some advice about how to approach his future love life, saying, "I went to the school and put it to William, particularly, that if you find someone you love in life you must hang onto it and look after it," she said.
"And if you were lucky enough to find someone who loved you, then you must protect it."
