Prince Harry has said he and his brother are "on different paths" and have "good days" and "bad days".
He was answering a question about rumours of a rift between himself and the Duke of Cambridge.
This year has seen Harry and Meghan split from their joint charity with William and Kate, the Duchess of Cambridge.
The Duke of Sussex said "inevitably stuff happens" – particularly with such a high-profile role and a family that lives under pressure.
He told the ITV documentary Harry & Meghan: An African Journey: "We are brothers. We will always be brothers.

"We are certainly on different paths at the moment but I will always be there for him as I know he will always be there for me.
"We don't see each other as much as we used to because we are so busy but I love him dearly.

"The majority of the stuff is created out of nothing but as brothers, you know, you have good days, you have bad days."
After the split was announced earlier this year, sources denied any feud – saying the move was "largely about preparing both couples for their future roles, which are obviously on divergent tracks".
The final day of the Africa tour was overshadowed by Harry's attack on the British tabloid press, in which he heavily criticised certain sections of the media for conducting what he called a "ruthless campaign" against his wife.
