Prince Harry says he gained confidence after Princess Diana's death thanks to an army sergeant

Prince Harry has revealed that he owes his renewed confidence following the death of his mother at a young age to his Colour Sergeant at Sandhurst.

He was speaking at a youth mentor training event at Mackie Academy in Stonehaven, Aberdeenshire on Tuesday, as part of The Diana Award set up in memory of his late mother, Princess Diana.

Talking to a group of pupils, the 32-year-old said his Colour Sergeant from his 2005 entry to Sandhurst military academy was his mentor.

"I was at a stage in my life when I was probably lacking a bit in guidance," he explained. "I lost my mum when I was very young and suddenly I was surrounded by a huge number of men in the army.

"He was someone who teased me at the right moments and gave me the confidence to look forward, to actually have that confidence in yourself to know who you are and to push forward and try to help others."

Harry was just 12, and his brother William was 15, when Princess Diana was killed in a car crash in Paris on 31 August 1997.

The royal did not reveal the sergeant's name as "he wouldn't want me to".

He also went on to praise 17-year-old pupil Jamie McIntosh, who received The Diana Award writing a book to help teenagers deal with grief after the death of his mother, Monica, to breast cancer.

"That's what's it all about, it's trying to stop other kids in your position having to go through what you had to go through and now your book is going to help everyone around you," added Harry.

"If anybody around me ever has any grief, especially close family, you feel as though you can help because you've got the experience and that's what mentoring is all about."

Meanwhile, the Prince is set to embark on a royal tour to the Caribbean in Autumn this year, he will visit Barbados, St Lucia and Grenada among other locations on behalf of his grandmother, the Queen.
