'Harry & Meghan' series drops on Netflix, Buckingham Palace, Kensington Palace and members of the royal family were not approached for comment

The Duke and Duchess of Sussex's documentary began streaming on Thursday, with Harry accusing the royals of having a "huge level of unconscious bias" and Meghan saying the media wanted to "destroy" her.

A senior source in the royal household countered the written statement of "Members of the royal family declined to comment on the content within this series" which appeared on a black screen at the start of episode one.

A Netflix source said that "communications offices for King Charles and the Prince of Wales were contacted in advance and given the right to reply to claims within the series".

In the first instalment of the six-part show, Meghan claimed "salacious stories" were "planted" in the lead-up to their wedding, with the couple "playing whack-a-mole" as the articles appeared.

The duchess also described her first meeting with the Prince and Princess of Wales, saying she was surprised at the "formality" of the royal family behind closed doors.

"I've always been a hugger, I didn't realise that that is really jarring for a lot of Brits," she said, revealing she was dressed down in ripped jeans and barefoot.

Harry said his wife being a US actress "clouded" his family's view of her while Meghan said the media would find a way to "destroy" her "no matter how good" she was.

The duke spoke of how there was a temptation in the royal family to marry someone who "fits the mould".

Speaking in the first episode of the Netflix documentary, he said: "I think, for so many people in the family, especially obviously the men, there can be a temptation or an urge to marry someone who would fit the mould, as opposed to somebody who you perhaps are destined to be with."

He added of his family's response to Meghan: "The fact that I was dating an American actress was probably what clouded their judgment more than anything else at the beginning, 'oh she's an American actress; this won't last'."

The documentary showed images of Princess Michael of Kent wearing a Blackamoor-style brooch to a Christmas lunch attended by Meghan in 2017, for which she later apologised.

"In this family, sometimes you are part of the problem rather than part of the solution. There is a huge level of unconscious bias," he said.

"The thing with unconscious bias, it is actually no one's fault. But once it has been pointed out, or identified within yourself you then need to make it right."

The docuseries also controversially used footage from Diana's Panorama interview, which William insisted should never be aired again.

In what is perceived as criticism of the King's parenting of Harry, the duke told of trying to cope with the loss of his mother Diana, who died in a car crash in 1997, "without much support or help or guidance".

He also said he was "literally brought up by a "second family" in Africa, saying they were "friends who literally brought me up".

On the aftermath of Diana's death, Harry said: "I was trying to balance the whole experience of being a young boy who was trying to deal with the loss of his mum without much support or help or guidance. It didn't seem right. It didn't seem fair."

Episode one revealed that Harry and Meghan filmed footage on their phones of their experiences at the culmination of the Megxit crisis, with the duke recording himself at Heathrow airport after his final royal public engagements as he prepared to leave the United Kingdom for the last time as a senior royal.

Harry said a friend told them they should document this particular chapter of their lives.

The footage forms part of the six-part series.

Harry and Meghan signed a lucrative deal, thought to be worth more than PS100 million ($A181 million) with Netflix and Spotify after quitting the monarchy.
