Range Rovers have been shipped from the UK to southern Africa for the Duke and Duchess of Sussex’s 10-day tour, because the Palace could not get hold of secure enough vehicles.
The 4x4s have been drafted in because organisers were unable to locally obtain cars suitable for Harry, Meghan and baby Archie.
It is understood that the cars for the trip were offered by Jaguar Land Rover, and were transported at no cost to the taxpayer.
The manufacturer has provided vehicles for the royal family for decades, including on foreign visits.
Meghan was pictured arriving in a British-registered blue Range Rover during her visit to the University of Johannesburg, South Africa, on Tuesday.
Harry and Meghan faced criticism in August after reportedly taking four private jet journeys in 11 days, rather than opting for commercial flights, despite speaking out on environmental issues.
The Duke has previously said that he would have a maximum of two children due to his concerns about climate change.
Speaking for a special edition of British Vogue in August, Harry said: “What we need to remind everybody is: These are things that are happening now. We are already living in it.
“We are the frog in the water and it’s already been brought to the boil. Which is terrifying.”
In September, Harry defended the couple’s “occasional” private flights and said they were necessary to keep his family safe.
He said during a visit to Amsterdam: “If I have to do that, it is not a decision that I want to take, but if I have to do that, then I will ensure, as I have done previously, and as I will continue to make sure that I do, that I balance out that impact that I have.”
He added: “I have always offset my CO2. I think part of the group discussion that we had earlier is ‘what is offsetting CO2′.”
Jaguar Land Rover has been contacted for comment.
