Prince Harry and Meghan Markle may be about to step down from their roles as senior royals, but the couple still had time to squeeze in one last engagement.

Over on their Sussex Royal Instagram the Duke and Duchess of Sussex shared unseen photos and video highlights from their meeting with young leaders from the Queen's Commonwealth Trust (QCT).

Topics covered at the meet included mental health, equal opportunities for all, and the importance of supporting youth leadership to help address global challenges and drive positive change around the world. 

The QCT aims to champion, fund and connect young leaders working to change the world.

The young leaders invited to the recent QCT meeting included social entrepreneur Kenny Imafidon, founder of the sTandTall charity Esther Marshall, and co-founders of Birmingham-based female empowerment organisation GirlDreamer, Kiran Kaur and Amna Akhtar.

The charity also shared a video online of the leaders’ exchange with the Sussexes.

In a video clip of the conversation, Harry says: “Without something to aim for, you can't unlock the potential, right?

“I bet it's made all the difference, right, to connect all of you guys.”

Megan adds: “To build this network, the QCT, so you have a support system and a sound board to continue to bounce these ideas off of.”

The Duke went on to highlight the import role the younger generation will have in bringing about change.

“There is no way that the older generation are going to be able to change their mindset unless it's their children who are influencing the change,” Prince Harry said in the clip.

Meghan also how vital it was to try to prevent issues before they start. “Let's not wait until there's a problem, and try to fix it let's try to prevent the problem from happening to begin with,” the Duchess said.

During the discussion the Duchess of Sussex was wearing an asymmetrical toffee coloured dress from Preen by Thornton Bregazzi, while Harry opted for a black suit with a white shirt, which looked slightly less formal thanks to the absence of a tie.
