Ms Bond also highlighted that this type of work, such as the scourge of landmines, is the best placed for Harry to carry out.
The former BBC royal correspondent told the Mirror: “I think this is precisely the sort of work that Harry should do. It is not only a hugely worthwhile cause, but it also connects him with his mother, which is something he yearns for.
“I think he is coming to recognise that the LA celebrity world is one in which he is not especially comfortable. And he seems quite willing to let Meghan take the limelight over there.
“He speaks frequently about a life of service, and trips like this certainly serve a very good cause indeed.”
During his visit, Harry was highlighting the threat of the munitions in Angola, the same nation that Princess Diana visited to urge the world to ban the weapons in January 1997.
The trip for his late mother took place just months before she died following a car crash in Paris on August 31, 1997.
In famous pictures, Diana, wearing a protective visor and vest, can be seen walking through a minefield being cleared by the Halo Trust.
