As the eldest daughter of Princes Andrew and Sarah Ferguson, the Duke and Duchess of York, people may think she could take on the Duchy.
But her gender prevents this, as the Royal Family operates on a system of male primogeniture.
The system means only male members can pass down an honour, princely or otherwise, to their children.
As such, both she and her sister Eugenie took on titles, but they can’t pass them on to their children.
