Meghan Markle's mother Doria Ragland could make her TV debut in the Sussexes ... trends now
While the Royal Family prepares to deal with the potential fallout of the show, the Duke and Duchess of Sussex are understood to have also aimed both barrels towards the media and the UK public.
The programme, titled 'Harry & Meghan', is expected to land on the streaming giant at some point in the next month, bringing renewed attention to the Royal Family after a recent race row.
It is expected that the six-episode series will include interviews with people close to the couple, as well as historians and cultural commentators, the Telegraph reports.
But the potential inclusion of Meghan's mother, Doria Ragland, is perhaps the most intriguing addition.
Doria Ragland (pictured with Meghan in 2018) is incredibly close with her daughter and plays a big part in her LA life

Prince Harry and Meghan Markle shared a number of highly personal images in the first trailer for their new Netflix documentary. In one clip from the documentary, Meghan is seen with her head in her hands apparently weeping

The 66-year-old is known to be particularly close to her daughter and son-in-law, and plays a big part in the lives of her grandchildren, Archie and Lilibet.
Ms Ragland, who rarely speaks in public, could make her TV debut in the programme, which is set to give the Sussexes the chance to explain why they felt they had to leave the UK.
Doria was the only family member of Meghan's to attend the royal wedding in 2018 and was pictured chatting to King Charles at St George's Chapel ahead of the ceremony.
Unlike Meghan's father Thomas Markle, Doria rarely speaks about her daughter in public, but Sussex fans are likely to see a little more of her as the Netflix series focuses on their life in LA, in which she plays a big part.
Recently, Doria appeared on a Zoom call with Meghan and little Archie as the Duchess spoke to an academic, who shared a screengrab of the call on Twitter.
And on her podcast Archetypes, Meghan recently revealed her mother still uses her childhood nickname - even though she is now a mother-of-two herself.
'My mum still calls me Flower,' Meghan admitted in a conversation with transgender actress Michaela J Rodriguez.
She added: 'I'll be a 41 year old Flower, that's fine.'
The nickname could well be linked to 66-year-old social worker Doria's new tattoo, which she debuted in September this year while walking around Los Angeles.
While she walked her two dogs near her home, fans spotted a flower tattoo on Doria's arm.
