The late Queen's death not only saw King Charles assume a new role as monarch, but Prince William also take on a wealth of new important responsibilities.
As well as gaining a host of new titles, including Prince of Wales, he also inherited the vast Duchy of Cornwall empire.
The Duchy of Cornwall is a private estate, estimated to be around £1billlion, which was established by Edward III in 1337 for his son, Prince Edward, and has been passed to the eldest surviving son of each monarch.
