Boris Johnson issued a cutting warning to King Charles over the Duchy of Cornwall, according to a royal author.
The revelation follows a bombshell investigative documentary, by Channel 4's Dispatches and the Sunday Times, that claimed the King has received "millions from public bodies and charities" through his private estate.
King Charles, then the Prince of Wales, was warned by the former Prime Minister that reparations to developing Commonwealth nations affected by slavery would result in selling the Duchy of Cornwall.
Royal Author Tim Shipman revealed that Johnson told the King: "I wouldn't talk about slavery if I were you, or you'll end up having to sell the Duchy of Cornwall to pay reparations to the people who built the Duchy of Cornwall."

The Prince of Wales owns the Duchy of Cornwall, Charles held the title at the time of the confrontation, however Prince William now owns the land after Charles became King.
The documentary claimed the royal estates had received almost £50 million of income from contracts with public bodies and charities, including the NHS and British Army.
A Duchy of Cornwall spokesman said it is "a private estate with a commercial imperative which we achieve alongside our commitment to restoring the natural environment and generating positive social impact for our communities".

Shipman wrote that Charles replied: "Well maybe, inadvertently, without intention I may have said something."
The clash occurred at the Commonwealth Heads of Government Meeting in the Rwandan capital of Kigali, where Shipman revealed that Charles feared that the Rwanda policy would create tension.
Charles addressed the Commonwealth Heads: "I cannot describe the depth of my personal sorrow at the suffering of so many as I continue to deepen my own understanding of slavery's enduring impact."
The King more recently made his first speech as Head of the Commonwealth at the Commonwealth Heads of Government Meeting in Samoa, where he told the Commonwealth leaders: "None of us can change the past, but we can commit with all our hearts to learn its lessons."
