Prince Harry will return to Britain just two weeks after his 40th birthday to celebrate the "remarkable courage and achievements of children living with complex medical needs," he said in a statement.
The Duke of Sussex embarked on a whistlestop visit in February after King Charles III was diagnosed with cancer and was back on U.K. soil in May to mark 10 years of the Invictus Games.
And as recently as last month he attended the Norfolk funeral of his uncle Sir Robert Fellowes.
His latest return will be to attend the WellChild Awards, in support of a charity he has been patron of for more than 15 years, having forged the relationship during his time as a working royal.
There is no suggestion Meghan Markle will join him and during many of his past trips to the U.K. she has remained in California with their children, Prince Archie and Princess Lilibet.
"I am once again honored to attend this year's WellChild Awards celebrating the remarkable courage and achievements of children living with complex medical needs," Harry said in a statement released by the charity.
"These incredible young people, along with the dedicated caregivers, nurses, and professionals who tirelessly support them, inspire us all. It is a true privilege to recognize such extraordinary individuals."
WellChild is a charity so close to Harry's heart that he donated a £300,000 [around $400,000] cut of the proceeds from his memoir Spare to the organization.
He also described in the book how a particularly emotional past appearance at the WellChild Awards brought him to tears and led to an argument between him and Prince William.
"The children were so brave," Harry wrote, "their parents so proud—and tortured. Various awards were given that night for inspiration, fortitude, and I was presenting one to an especially resilient preschooler.
"I walked onstage, began my brief remarks, and caught sight of Meg's face. I thought back to a year ago, when she and I attended this event just weeks after
taking that home pregnancy test.
"We'd been filled with hope, and worry, like all expectant parents, and now we had a healthy little boy at home. But these parents and children hadn't been so lucky. Gratitude and sympathy converged in my heart, and I choked up. Unable to get the words out, I held the lectern tight and leaned forward."
Harry got a text shortly afterwards from Prince William, who was on a royal tour of Pakistan, expressing concern for Harry's wellbeing.
"I'd become emotional in front of a roomful of sick kids and their folks just after becoming a father myself—nothing abnormal in that," Harry wrote.
"He said I wasn't well. He said again that I needed help. I reminded him that I was doing therapy. In fact, he'd recently told me he wanted to accompany me to a session because he suspected I was being 'brainwashed.'"
They had a 72-hour argument off the back of the event and Harry said he still sometimes looks back over the text messages they sent each other.
The visit will raise inevitable questions about whether Harry sees his family just weeks after his 40th birthday on Sunday.
