Prince William and Princess Catherine have been praised for "making a difference" in a stark comparison to "show offs" Prince Harry and Meghan Markle ahead of a new documentary.
The Prince of Wales will feature in a new ITV program which will follow the future King's long-term advocation for tackling homelessness in the UK.
Leo Burley, director of the documentary, said they have been "following Prince William and The Royal Foundation through the first year of the Homewards programme", and everyone they have filmed with "has welcomed the spotlight that William and Homewards are placing on the UK's homelessness crisis".
Speaking to GB News, royal biographer Angela Levin said Prince William has been "very busy" in his work with the Homewards charity and has been so involved with the homelessness cause "because of his mother".

Levin explained: "We mustn't forget that in 2009, he slept out in the street to see for himself what it was like. And he also helps people who are selling the Big Issue magazine.
"He wants to do this so badly because of his mother. She took them to see people who were homeless."
Levin also said that Prince William is keen to "get his children involved" in helping with the cause, and has donated money from his and Princess Kate's own foundation to assist the charitable causes which tackle homelessness.
Sharing her thoughts on the new documentary, host Isabel Webster compared William's upcoming program to Prince Harry and Meghan Markle, claiming it is "what they should have done" when creating their documentary series.

Isabel told GB News: "This is an example of what the Duke and Duchess of Sussex should have done when making a TV documentary, going behind the scenes and doing something noble and worthwhile rather than complaining.

"This would be the Prince and Princess of Wales showing that they're making a difference."
Levin agreed with Isabel, adding: "That's what they're doing, they're doing everything they can in so many different ways to help the country and people who need help.
"Unfortunately, Harry and Meghan do everything that will help them and give them money. They're fantastically interested in money and not actual people."
Noting her previous work with the Duke and Duchess, Levin revealed: "When I went around with Harry when I was doing his biography, he was marvellous with ex-military people, wonderful with them. But Meghan is very awkward. She's not used to talking to people like that, and I don't think she wants to.

"So that's very difficult. Their idea is to show off and be wonderful, whereas William and Catherine's is to help."
When asked about Prince William's latest appearance at England's latest football match against Switzerland in the Euro's tournament, Levin praised the royal and how he "allows himself to be normal".
Levin told Eamonn and Isabel: "Seeing him at the football was wonderful because there you see someone full of life, full of enthusiasm, he was chewing his fingers, gritting his teeth.
"You see a man who is actually natural and himself, but can become very dignified as heir to the throne and looking after this amazing country. He cares about England, and he allows himself to be normal and to do these things that are really important to him."
