British royal Prince Harry has broken his silence over the shocking images which showed him partying naked in Las Vegas last year, admitting he let himself and his family down.

Photographs of the young royal cavorting in the nude with a group of women in his Sin City hotel suite emerged in August and hit headlines across the world.

At the time of the incident, the Prince was on leave from the British Army, in which he serves as an Apache helicopter gunner, and he admits he should have shown more restraint during his vacation.

He says, "It was probably a classic example of me probably being too much Army and not enough Prince. It's a simple case of that. I was in a private area and there should be a certain amount of privacy that one should expect. At the end of the day, I probably let myself down, I let my family down, I let other people down."
