Prince Harry should "man up" and stand "shoulder to shoulder" with his brother in an investigation into the BBC's Diana interview, a royal expert has claimed.
Prince William has welcomed an inquiry into allegations that BBC journalist Martin Bashir forged documents to convince Princess Diana to speak with him for a Panorama interview in 1995.
Prince Harry is yet to comment publicly on the matter and a royal expert has suggested his silence speaks volumes about his relationship with Prince William.
Ingrid Seward, editor-in-chief of Majesty Magazine, told the Sun : “He is normally so keen on letting his opinions be known — why hasn’t he done so in this case and stood by his brother to share the responsibility.
“It is odd he hasn’t spoken out about the BBC and Bashir case as he has been speaking out a lot about other things recently.
“Harry should really man up and forget the fallout with his brother.
“They should be standing shoulder to shoulder on this one.”
The brothers are said to have fallen out earlier this year over Harry's decision to leave the Royal Family.
Prince William has been in talks with the BBC over the past two weeks after the allegation once again remerged.
Diana's brother Earl Spencer alleged that he was shown "false bank statements" by Bashir and they were used to help the reporter gain access to the princess.
According to the BBC, Diana wrote a note saying she did not see the false bank statements and they played no part in her decision to speak with Bashir.
The BBC has said the investigation will begin straight away and seek to discover what steps the broadcaster and Bashir took to land the interview.
Prince William said on Wednesday: “The independent investigation is a step in the right direction.
“It should help establish the truth behind the actions that led to the Panorama interview and subsequent decisions taken by those in the BBC at the time.”
The princess sent shockwaves through the monarchy with the Panorama interview, which included candid details about her marriage and the Prince of Wales's rumoured relationship with Camilla Parker Bowles, his now wife.
Diana also questioned Charles's suitability as king.
A month later, the Queen urged the separated couple to divorce, which they did in 1996.
The princess died in 1997 in a car crash in Paris.
TV watchdog Ofcom says it will not launch its own investigation into the BBC Panorama controversy.
It says it "does not have regulatory remit to investigate" the issues under the charter.
"However, we think it is essential that the BBC ensures that the concerns raised about this programme are investigated thoroughly," it said in a letter to the BBC.
"Therefore, we welcome your announcement yesterday of a fully independent inquiry, to be led by Lord Dyson into the events surrounding the making of the original programme, as well as the BBC's investigation of it in 1995 and 1996.
"We will follow the inquiry and its conclusions closely," it added.
