“For Harry, there can be no meaningful rehabilitation as a royal without reconciliation. His father’s recent health scare has added a sense of urgency to that quest.”

The King is believed to be spending time at his Balmoral home and it is thought he has not seen Harry since the duke rushed to his father’s side after Charles’s cancer diagnosis was announced in February.

The WellChild Awards celebrate the inspiring qualities of some of the country’s seriously ill young people and the dedication of those who keep them healthy and happy, including health, social care and education professionals.

Harry regularly attends the annual event hosted by WellChild, the national charity which provides a nationwide network of nurses, home makeover projects and family support programmes.

Before the big event, the duke will attend a reception to meet the category winners and their families before joining guests for the private awards ceremony where he will present the Most Inspirational Child (aged four to six) award and deliver a short speech.

Last week, it was also confirmed that Harry will be in Southern Africa early next month as part of a visit for his charity Sentebale, which he co-founded in 2006. It will be his first trip to the region since 2019 – and it appears to be a solo visit with no mention so far of wife Meghan Markle joining him.

The trip will see him gather world business leaders and philanthropists to work towards fostering prosperity in Southern African communities, specifically focused on young people. His Sentebale charity, which he co-founded with Prince Seeiso of Lesotho in 2006, will bring together leaders from Google ’s charitable arm and several other companies and organisations for a series of meetings and discussions in Lesotho and Johannesburg, South Africa.
