Prince Harry and Meghan Markle are due to land in the UK this Sunday, the first time since their trip for the Queen’s Platinum Jubilee celebrations in June.
During their visit it is expected they will attend two events in the UK, as well as travelling to Germany to promote the Invictus Games.
It is yet to be confirmed whether the couple will visit the Queen who is currently residing in Barlmoral, as concerns surrounding her health continue.
The 96-year-old monarch, who has faced ongoing mobility issues, will also not travel to London for the appointment of the next prime minister, traditionally the event takes place at Buckingham Palace.
A Palace spokesman confirmed the decision on Wednesday.
Earlier this week Nelson Mandela's grandson slammed Markle for suggesting that her marriage to Prince Harry caused scenes of joy in South Africa.
The Duchess said an actor told her the scenes could be compared to the anti-Apartheid campaigner's release from jail after 27 years in 1990.
Zwelivelile 'Mandla' Mandela told MailOnline that the scenes from both events "cannot be equated to as the same" before admitting he was "surprised" by Meghan's statement.
The Duchess of Sussex claimed in her interview with The Cut Magazine that three years ago a cast member of the Lion King had made the comparison between her royal wedding and Madiba's historic walk to freedom.
In the article called 'Meghan of Montecito,' the Duchess recalled an encounter she had at a 2019 London premiere of a live-action version of the classic film.
She claims that an actor from South Africa pulled her to one side to tell her: "I just need you to know: When you married into this family, we rejoiced in the streets the same we did when Mandela was freed from prison."
Nelson Mandela's family are said to have been shocked at the story, with 'Mandla' Mandela, an MP and Chief of the late South African President's Mvezo tribe, speaking out on the statement.
He told MailOnline: "Madiba's celebration was based on overcoming 350 years of colonialism with 60 years of a brutal Apartheid regime in South Africa. So It cannot be equated to as the same."
It comes as a US insider has said Markle's star is waning in the American media with Kate, Duchess of Cambridge rising in public prominence.
"Meghan is sort of regarded as tabloid fodder these days," said the insider.
"I wouldn’t say her popularity has waned but her star draw has. She was riding on the cusp of being the Duchess, but a lot of their projects have failed and some of the lustre has gone.
"It would be unfair to say she’s not popular but we are doing less on her. We are more likely to do something on William and Kate now," they told The Telegraph.
