William pays tribute to Diana in upcoming homelessness documentary.

Prince William has mentioned his brother, Prince Harry, publicly for the first time in years, as he paid tribute to their mother in his upcoming documentary.

The Prince of Wales recounted an emotional childhood memory of the late Princess Diana taking him and his brother to visit a homeless shelter when he was 11-years-old.

“She took Harry and I both there. I must have been about 11, I think probably at the time, maybe 10,” he said.

The last time William spoke about his brother publicly is thought to be six years ago, when the pair were interviewed at Royal Foundation Forum in 2018.

In a touching tribute to his mother’s character William added: “I had never been to anything like that before and I was a bit anxious at what to expect. But mother went about her usual part of making everyone feel relaxed, having a laugh and joking with everyone.”

Meanwhile, King Charles is set to return to his normal schedule of overseas tours next year, as he continues cancer treatment. The monarch will complete full tours during the spring and autumn, provided doctors sanction the travel.
