The YouTube clip, said to have been recorded in January last year, shows the Duke of Cambridge in a row with a photographer allegedly filming his family on a bike ride near their Anmer Hall home in Sandringham.
During the clip, an angry Prince William can be seen telling the photographer: “You were out here looking for us.”
His wife Kate Middleton can be heard saying: “We are out for a bike ride with our children, we saw you by our house.” The duchess and the royal couple’s three children are not visible in the video.
In the video, the off-screen photographer claims he was only using public roads and denies any wrong doing.
The clip of the 2021 incident was posted on social media last week and had been viewed more than 20,000 times as of Monday (27 June).
Kensington Palace said the video is a breach of the family’s privacy, The Telegraph reports. The newspaper adds that it understood staff were trying to get the video removed.
The footage is no longer available on the poster’s YouTube channel at the time of writing.
During the clip, William says: “How dare you behave like you have done with our children? How dare you? Stalking around here looking for us and our children?
“I’m out for a quiet bike ride with my children on a Saturday and you won’t even give me your name. You’re outrageous, you’re disgusting, you really are…Why are you here?
“Thanks for ruining our day…I thought you guys had learnt by now,” William reportedly says as he rides off.
