Not Likely That He Will Get Another Title
Is Prince Harry going to get a new title once his father ascends the throne? This does not seem likely. It is possible if Prince Charles hands him a new dukedom, which is indeed possible. However, there is a good chance that he will simply stay the Duke of Sussex, with his wife Megan as the Duchess of Sussex.
There Is More To It Than That
Do you find that all confusing? Well, this is not the end of it by far. At the moment, William is also the Baron Carrickfergus and Earl of Strathearn. When his father becomes the ruling monarch, the younger man will take on new duties and responsibilities. And yes, these come with changes in titles as well.
