Prince Harry and Meghan Markle will attend a UN General Assembly session on Monday to deliver a memorable speech.
The Duke of Sussex is set to say a few words about Nelson Mandela in a tribute.
However, Harry’s speech has come under fire by various royal experts, including the Duke’s biographer Angela Levin.
In a fresh attack on Tuesday, Ms Levin wrote: “Harry giving speech about Nelson Mandela at UK on Monday. Would he have got it without being a member of the royal family that he couldn’t wait to leave?”
Meanwhile, GB News presenter Eamonn Holmes added: “How has Prince Harry been invited to the United Nations?”
He inquired: “What’s he got to say that will change the world, or influence the world?”
Vanity Fair royal editor Katie Nicholl, however, supported Harry: “Joking aside, I think if climate change is on the agenda, then Harry is probably going to be pretty impressive on that front.”
