Prince Charles has reportedly told friends he wants the BBC to stop showing clips of Martin Bashir's Panorama interview.
The Duke of Cornwall is yet to issue a formal statement following the publication of Lord Dyson's damning report.
But he has apparently told aides he is annoyed the broadcaster keeps airing parts of the 1995 programme in news reports.
A source told the Mail on Sunday "there is a feeling that the BBC shouldn't be showing any footage at all from the interview".
Princess Diana - the prince's ex-wife - infamously told Bashir "there were three of us in the marriage" during the sit-down.

She was talking in reference to Charles' relationship with Camilla Parker-Bowles, who he later married.
Diana, the Princess of Wales, tragically died in a car crash in Paris in 1997.
She and Charles had divorced a year earlier.
Lord Dyson, a former Supreme Court justice, published his findings on the interview on Thursday.
His report found that Bashir had lied and deceived his way into securing his explosive chat with Diana, and the internal investigation led by Lord Hall into the matter was "woefully ineffective".
Prince William - Charles and Diana's eldest son - issued a statement after the publication in which he slammed the "rogue reporter" and spoke of his "indescribable sadness".
He also said he and Prince Harry, his younger brother, had been failed by the BBC.
While he has not spoken in public, Charles is said to have "fully supported" William's statement.
Harry issued his own statement from his home in California, which said: "To those who have taken some form of accountability, thank you for owning it."
The BBC also wrote to members of the royal family and others affected by the scandal.
Bashir, who recently quit the news organisation on health grounds, told the Sunday Times he was "deeply sorry" to Harry and William.
But he added: "I never wanted to harm Diana in any way and I don’t believe we did.
"Everything we did in terms of the interview was as she wanted, from when she wanted to alert the palace, to when it was broadcast, to its contents ... My family and I loved her."
Lord Dyson's report had ruled that Bashir used fake bank statements to get to Diana and Earl Spencer, her brother.
The scoop, widely hailed at the time, was dogged for rumours of subterfuge for decades - later found to be true.
