The trip will provide the couple with an opportunity to showcase causes they're heavily involved with as well as develop and deepen the various existing relationships between the UK and Africa.
1. Waiting for Archie
Only a few images have been shared of baby Archie so far, but we are expecting him to appear at his first official engagement while in South Africa.
When and where will depend on how he feels and whether his parents feel he's ready.
When he does appear, cue a collective: "Hasn't he grown!" followed by extended deliberations over whether he takes after his mother or his father.
