Prince Harry has begun his final day in Britain with a trip down memory lane. He has marked the fourth day of his UK visit by meeting those involved in the Diana Award, which was created to in honour of Princess Diana following her death. The Duke of Sussex attended the centre in the heart of London today (September 11), hearing stories from young people about how social action has positively affected their mental health. He was able to speak to and listen to around 40 youngsters when he was present, following a panel with Lottie Leach, Elsa Arnold and Idorenyin Hope Akpan, which was chaired by Dan Lawes, a previous winner of the charity’s Legacy Award.

In a statement, the prince reflected on the day: “Getting involved in peaceful social action takes courage and determination. “Young people see the issues society faces close up – whether that’s poor mental health or the consequences of inequalities. “But you don’t stand still; your empathy and compassion drive you to make change. Purpose combined with action can help overcome a sense of hopelessness, and that’s exactly what you’ve shown today. “When you spoke about how taking action gave you purpose, confidence and joy, it was more powerful than any statistic. It reminded me that agency is not a luxury for young people, it is a lifeline. “My mother believed in the power and agency of young people to positively impact the world. The Diana Award continues her legacy by putting young people at the heart of everything they do. “Today is a perfect example of that. My message to everyone is don’t stand still, don’t stay silent – make them hear you because you speak for the majority.” READ MORE: Prince Harry issues update on Midlands visit Today’s visit comes just hours after the prince met with his father, King Charles, for the first time in nearly 20 months. It was reported the reunion lasted only 54 minutes, resulting in the Duke seemingly looking “optimistic and upbeat” at an Invictus reception on Wednesday evening, according to body language expert, Judi James. She said: “Harry’s rather impish-looking smile today had echoes of his famous grins as a child, which in turn gave the smallest possible clue that he was going back into his role as a son again with this meeting with Charles on the cards. “His smile looked optimistic and upbeat as Harry was clearly in a world he knows best here, meeting and hugging a paralympic pal as he joins up for a visit. “There was still one non-verbal signal of anxiety though with the way his fingers were tucked into his shirt and his belt in the kind of stomach or waistband touch he often does when he’s feeling vulnerable.” This event was only an hour after he left Clarence House, with a reporter having asked the prince how his father was, with the Duke simply stating in return: “Yes, he’s great, thank you.”
