Buckingham Palace yesterday confirmed the Sussexes, including newborn Archie, will be flying to South Africa this autumn for their first trip as a family.
But while in the continent, the trio will then split as Harry visits Angola, Malawi and Botswana, while Meghan stays behind with her son.
And sources have reportedly confirmed the reason they will be missing out on the second part is because the train Harry will travel in is not suitable.
A source told The Sun’s Fabulous Digital: “The Duchess will stay with her son, who will be just under five months old when the visit takes place.
“The Duke will be travelling in a very small plane to Botswana, Angola and Malawi and due to the size of the aircraft and some remote locations that Harry will be visiting, it is not possible to take a small baby.”
But despite missing out, Meghan and Archie will apparently continue their stay in South Africa rather than travel back to the UK.
The short visit is reportedly part of a much longer tour of this part of the world the couple will take – with the second part taking place next year.
Confirming the visit yesterday, a statement on the Sussexes’ Instagram account read: “TRH The Duke and Duchess of Sussex are excited to announce that they have been asked to carry out a tour to Southern Africa this autumn.
“The Foreign and Commonwealth Office have requested a visit to South Africa as well as The Duke carrying out visits to Malawi and Angola. His Royal Highness will also do a short working visit to Botswana on route to the other countries.
“The Duke and Duchess are really looking forward to meeting so many of you on the ground and continuing to raise awareness of the high impact work local communities are doing across the commonwealth and beyond.
“This will be their first official tour as a family!”
Harry is said to have a deep love of Africa, which he once described as the place “where I feel more like myself than anywhere else in the world”.
After just two dates with Meghan, who was then an actress, a smitten Harry whisked her to Botswana for five nights where they camped under the African stars.
The couple also returned to Africa again the summer after, before Harry took his love of the continent even further.
The Prince, when designing Meghan’s engagement ring, had a diamond from Botswana installed in its centre.
Harry first visited Africa just after the horror death of his mum Princess Diana in 1997, where he vowed “I wish I could spend more time (here)”.
