Prince Andrew feels betrayed by successive UK Prime Ministers for distancing themselves from him.
He regrets agreeing prematurely to a £12 million settlement with Virginia Giuffre.
The Prince was allegedly pressured into the agreement after a conversation with Boris Johnson in January 2020.
Johnson advised him that settling would be best for everyone involved.
Andrew denies Ms Giuffre's claims of sexual assault when she was 17.
He also holds a grudge against David Cameron, who was all over him for hosting events at Buckingham Palace.
Andrew's involvement in the ongoing investigation into Jeffrey Epstein and Ghislaine Maxwell is unknown.
Buckingham Palace has declined to comment on the issue.
Mr Johnson has also declined to comment.
