Princes William and Harry join forces as they deliver emotional message amid fallout

Prince Harry and Prince William have seemingly reunited for the first time since attending their father, King Charles III's, Coronation back in May.

And it was for an emotional and heartfelt reason.

The brothers, who have been at loggerheads in recent months following Harry's book Spare being published, both attended the Diana Awards today - albeit virtually.

The Diana Award is a cause close to the brothers' hearts because it was set up in 1999 in memory of their late mother, Diana the Princess of Wales who tragically died two years prior in 1997.

The Diana Award "honours young people who work to improve the lives of others" with the charity "empowering young people to make positive change".

British journalist Omid Scobie, who is best-known for co-authoring the book Finding Freedom, has today revealed that the Princes united virtually for this special occasion.

Taking to Twitter to share some photos from behind-the-scenes, Omid penned: "Earlier this month, Prince Harry and @DianaAward chief executive @Ttall met with the charity's Roll of Honour alumni in LA for a 'Conversations for Change' session—a program created to bring youth together around a key social issue."

"Before the discussion, the Duke of Sussex surprised four of this year’s Diana Award recipients with their certificates," he added.

Omid then continued: "Today, June 30, a virtual ceremony honoured 189 young changemakers from 31 countries, with both Prince William and Prince Harry separately recording videos to help introduce some of the recipients."

In the video Harry said: "When someone steps up to be of service, they automatically join this collective.

"No one is ever a conduit for change alone. Each one of us has the ability to help create a more equitable world."

While the Prince of Wales said he was "proud" to continue his late mother's belief, with him saying: "Today, we recognise the power of all young people—the power to challenge the status quo, to confront injustice, and to inspire meaningful change.

"To all the award recipients, I extend my heartfelt congratulations. Your accomplishments are a testament to your passion and commitment to creating positive change.

"You are the torchbearers of hope and inspiration, lighting the way for others to follow."

The brothers were not in the same room when filming their pieces to camera, which was apparent by their backgrounds and the lighting surrounding them.
