Transcript for Pressure increases for Harry, Meghan to delay Oprah Winfrey interview
We are going to turn to the latest in that brewing fight between Meghan Markle and Buckingham palace. ABC news confirmed Meghan and Harry will not be a part of the palace's investigation into the accusations that Meghan bullied her staff and James Longman has the latest. Good morning, James. Reporter: Good morning, Cecilia. The decision to launch a bullying probe really has sent shock waves here with suggestions that more people may want to come forward with their stories. But with an investigation like this, the palace risks all kinds of secrets coming to light. This morning, anticipation growing for Harry and Meghan's sit-down interview with Oprah two days away. Promo clips amplifying the tension. Markle calling them out directly. I don't know how they could expect that after all of this time we would still just be silent if there is an active role that the firm is playing in perpetuating falsehoods about us. Reporter: The duchess suggesting she won't be holding anything back. If that comes with risk of losing things, I mean, I've -- there's a lot that's been lost Reporter: At least 63 countries are expected to broadcast the interview but with 99-year-old prince Philip still recovering from a heart procedure and expected to remain in the hospital for a few more days there is increasing pressure for Harry and Meghan to delay the broadcast. We know a lot about how Harry and Meghan feel and it's clear they feel strongly they were unfairly treated but I think the test of this interview will be whether or not people who are unsure what to think who are maybe in the middle here are persuaded by anything they put forward. Reporter: This morning ABC news learned the couple will not take part in the palace's investigation into bullying allegations against Meghan. But senior aides are expected to be questioned. Allegations published in "The times of London" from one claim the duchess drove two personal assistants out of the household. Meghan firing back saying it was a calculated smear campaign. The couple has had a complicated relationship with the British tabloids as early as 2016. The duke of Sussex expressed concerns over coverage of his then girlfriend calling out the racial under tones and accusing some of outright sexism and racism. Buzzfeed had 20 headlines. Treatment of Meghan versus Kate Middleton. Harry drawing comparisons with his late mother Diana. My biggest concern was history repeating itself. Reporter: The major criticism here is that there was no palace investigation into prince Andrew's far more serious allegations around Jeffrey Epstein. The palace is accused of a double standard. We are hearing in the last few minutes tt prince Philip has had a successful procedure at St. Bartholomew's moved back to king Edward hospital where he was previously. Thank you so much. So many questions and bring in omid Scobie and Robert good morning to you both. Thank you for being with us. Robert, I want to start with you. Reports out that more staffers might be coming forward about these allegations of bullying. Any idea what they could be saying and what this might do to the investigation? Well, I think that actually this is going to make it a much wider investigation. They've opened a can of worms by saying they don't tolerate bullying and much about wider than Meghan itself. It involves other senior members of staff so I personally have spoken to a couple members of staff, former members who said a lot of these allegations were logged and nothing was done about it. So I think to actually focus all attention on Meghan is particularly unfair. It seems to me that, you know, in a hierarchical situation there's bound to be situations this the palace have really opened something that they probably won't be able to put back in the box. The timing is, of course, a huge part of the story. The allegations coming forward from the palace just as Meghan and Harry are about to drop this big interview with Oprah. Is this the right time for Meghan and Harry to be doing this interview? Yeah, I think a lot of people are questioning the timing of Harry and Meghan finally speaking up, of course, it comes unfortunately while prince Philip remains in hospital but have to remember this was really held back by Meghan's Prive case and it wasn't until they won it and proved their point they were able to confirm with Oprah they finally wanted to set the record straight and they are looking forward to having their story out there. Robert, we heard Meghan mention the phrase the firm. Can you explain more about that and how her using that word might be going over with the palace right now? Well, I think that to be fair I think Meghan got it wrong. It was used by the duke of Edinburgh to include the royal family. It doesn't include the palace. It's simply to refer to members of the royal family. I think from that clip we've seen that -- where she refers to it I got the impression she's talking about the wider palace itself. So I think it just might be a bit of a misunderstanding. It all sounds dramatic like another episode out of "The crown" so I'm not sure why she used that expression. It does sound like it could be coming out of "The crown." The queen is expected to speak publicly Sunday, the same day we are going to likely see this interview from Harry and Meghan. This is going to be quite the split screen. Yeah, this is going to really highlight the difference between the priorities of the sussexes and, of course, the monarch. For the queen duty has always come first and Harry and Meghan went against the grain by prioritizing their family to find a space they could thrive in putting duty in second place. That hasn't gone down well here in the uk. When people see their side of the story, mainzs might be changed. It is a fascinating story and thank you both for being with us.
