Princess Diana calmly responded to a misogynistic remark from the crowd.
While attending a walkabout, the mother of two was asked where her children where.
Diana then looked downwards and simply smiled before saying: "At school."
The resurfaced video is now going viral on the internet. Responding to the clip, netizens on social media commented.
"No one would ever ask a man 'Where are your children?' one follower said.
"She answered that with so much class," remarked another. A third added: "Diana handled it perfectly."
Princess Diana passed away in 1997 in a Paris car accident alongside boyfriend Dodi Al-Fayed.
