With his father standing behind him Harry said: "It is your selfless drive to affect change, whether that is to improve the lives of those who are on the wrong path, to save an important piece of our national heritage or to protect a particular species under threat, which William and I draw inspiration from every day."

During the speech a bee buzzed close to the duke and he fluffed his lines and quipped "that bee really got me".

Meghan and the Duchess of Cornwall broke into a fit of giggles as Harry tried to keep his composure.
