Prince William and Prince Harry have paid tribute to their late mother Diana, Princess of Wales.

The two royals have honoured their mother's charitable legacy in the foreword of a book which celebrates the 15th anniversary of the Diana Princess of Wales Memorial Award - a charitable organisation that was set up in 1999 to support and encourage children and teenagers.

According to the Daily Mail newspaper, the princes wrote: "We believe, when encouraged and supported, that young people have the ability to change society for the better. We know that our mother - in whose memory this award was established - felt the same and would be proud of its achievements to date.

"Having met young people working with the charity in Newcastle and in London, we were struck in both cases by their deep and lasting sense of social responsibility.

"These young people were working hard to tackle the social issues that affected them - such as bullying or social exclusion - the Diana Award empowered them to do more."

The charity was established two years after Diana's tragic death in 1997. Since its inception the Diana Princess of Wales Memorial Award has helped over 40,000 young people.

This year, Ellie Louise Harris-Beard was awarded the Diana Champion Fundraiser Award for setting up the charity Cords4Life.

After finding out that she was to be honoured, Ellie said: "I was quite shocked. I didn't know what to say. It's exciting."
