The two royals lost their mother in a fatal car crash in Paris in 1997, and to mark the 20th anniversary of her tragic passing, the Diana Award - a charity which was established in 1999 to support young people's ability to change the world - has announced plans for a number of initiatives aimed at promoting the late Princess's qualities of kindness and compassion.

Prince William, 34, and Prince Harry, 32, will take part in a number of the planned events, which will include a National Kindness Day - where people are encouraged to do something nice for the sake of another - in March.

Tessy Ojo, chief executive of the Diana Award, said in a statement: "What's 2017 all about? It's about celebrating the legacy of Princess Diana, 20 years on. Diana, Princess of Wales was known worldwide for her values of compassion, her values of kindness and her values of service to others.

"Twenty years on, we at the Diana Award know that her values and her legacy live on through the tens of thousands of young people who only know her as an historic figure, but are committed to continuing those values."

As of yet, the events which will be attended by the royal brothers has not been confirmed, but Tessy claimed both Princes have been kept up to date and fully support the proposed programme.
