The Duchess of Cambridge has stepped up to support Prince William in the wake of Prince Harry and Meghan Markle’s Oprah Winfrey interview, a royal source has claimed.

Kate Middleton, 39, ‘sympathises’ with her husband’s feeling of ‘upset and anger’ after the Duke and Duchess of Sussex levelled explosive claims against the Royal Family in the TV interview.

The Duke of Cambridge has been leaning on his wife even more after his initial conversations with Prince Harry after the interview ‘didn’t go too well’.

‘Kate has been there for William recently, especially after his conversations with Harry didn’t go too well,’ Kate Nicholl told OK! magazine.

‘Kate has always remained loyal to William despite how close she was to Harry. Her loyalties are with her husband and their family. Even though she’d love peace and harmony, she sympathises with William’s upset and anger.’

She added the birth of Pippa Middleton’s daughter Grace has been a huge source of joy.

‘Pippa’s baby joy has been a welcome distraction for Kate after a difficult few weeks,’ Katie said. ‘It’s really put a smile back on her face.’

It comes after CBS presenter Gayle King said she had spoken to the Sussexes who told her that Harry had talked to the Duke of Cambridge and Prince of Wales after the interview.

But she said the conversations were ‘not productive’ and the Sussexes were keen for the ‘royals to intervene and tell the Press to stop with the unfair, inaccurate, false stories that definitely have a racial slant’.

Ms King, 66, who is also close friends with Oprah, failed to give any examples of the stories she was referring to, but added that Meghan had ‘documents to back up everything that she said on Oprah’s interview’.

She told CBS This Morning: ‘Well I’m not trying to break news, but I did actually call them to see how they were feeling, and it’s true, Harry has talked to his brother and he has talked to his father too.

‘The word I was given was that those conversations were not productive. But they are glad that they have at least started a conversation.

‘And I think what is still upsetting to them is the palace keep saying they want to work it out privately, but yet, they believe these false stories are coming out that are very disparaging against Meghan, still.

‘No one in the Royal Family has talked to Meghan yet, at this particular time.

‘And I think it’s frustrating for them to see that it’s a racial conversation about the Royal Family when all they wanted all along was for the royals to intervene and tell the Press to stop with the unfair, inaccurate, false stories that definitely have a racial slant.

‘And until you can acknowledge that, I think it’s going to be hard to move forward. But they both want to move forward with this and they both want healing in this family. At the end of the day, that is Harry’s family.’

During their interview this month the Duke and Duchess of Sussex said racism drove them out of Britain and claimed their son Archie was denied the title of prince because he is mixed-race.

Meghan Markle claimed she entered the Royal Family ‘naively’ and didn’t do any research about her husband or the institution and Prince Harry accused his father Prince Charles of refusing to take his calls when the pair emigrated to the US last year.

Last week, Prince William defended the Royal Family, saying it was ‘very much not a racist family’ while on a trip to a school in London.
