The 32-year-old royal has confessed that rather than dreaming of the day he's crowned king of England, he used to think about becoming an astronaut or a police officer when he was a little boy.

He shared: "When I was younger, I dreamt of being an astronaut.

"I've always wanted to say I'd be something like a fire breather but that's far too alternative. So sadly, just a policeman for me."

The Duke of Cambridge - who is currently on an eight-day tour of Japan and China without his wife, Duchess Catherine, and their 19-month-old son Prince George - went on to admit that while he has a huge respect for astronauts and takes "his hat off for those who do go up there", he doesn't think he'd be confident enough to embark on a trip to space.

He joked: "I don't think my Eurocopter will make it that far up. It seems like an awfully long way from the ground."

Meanwhile, it was revealed yesterday that William has passed his exams and will start work as an air ambulance pilot in the summer.
