Prince Harry believes people need to "acknowledge the past" in order to "move forward" and create a fairer society.
The 35-year-old royal and his wife, Meghan, Duchess of Sussex, participated in a video call for the Queen's Commonwealth Trust - for which they are the president and vice-president respectively - to discuss fairness, justice and equal rights with youth leaders.
And during the call, Harry said all Commonwealth nations must accept their past mistakes in order to learn from them.
He said: "When you look across the Commonwealth, there is no way that we can move forward unless we acknowledge the past. And I think so many people have done such an amazing, incredible job of acknowledging the past and trying to right those wrongs, but I think we all acknowledge on here that there's so much more still to do.
