Referring to the Monarchy as "The Firm", he said: "But then I decided to stay in [The Firm] and work out a role for myself."

The Prince revealed he had come close to a break down a number of times in the past, but was now determined to use his royal role as a force for good.

The Prince said he disliked aspects of life in the public eye but was now determined to lead a relatively normal existence.

In an interview with the Mail on Sunday, the Prince said he had been motivated to continue his Royal duties by his grandmother, the Queen.
