Queen Elizabeth II once scolded a photographer for ruining Princess Diana's horse riding lessons at the border.
Former royal photographer Jim Bennett admits that Her Majesty reprimanded him for providing too many intimate shots to a very frightened Diana.
Jim told The Sun's royal editor Matt Wilkinson: “Many years ago, back in the 1980s, the Queen was trying to teach Diana to ride along with some grooms.
“They were at Sandringham, and the Queen had taken her out and for some unknown reason decided to drive her down the main road towards Anmer Hall, which is where William and Kate now live.
He added: “But she was coming down that road and they were travelling together.
“They saw us and I was hoping they would move a little bit off course, but obviously Diana was very unstable on the horse.
“I mean, he was just telling me firmly, 'Please let me continue with this. And let me finish.'”
Jim then added that he continued taking photographs of Diana until the Queen got off her horse to make a scathing comment at him.
He added: “But they kept coming and we took the pictures.”
“And literally, when they got to us, she looked at me and said, 'You're a horrible little man.'”
He admitted: “At that very moment, I felt like I wished there was a big hole that I could disappear into, because just for her to say it and look at you, she just had something.”
