Charles Spencer, the late Princess Diana's brother, shared a touching tribute on the 23 anniversary of his sister's tragic death on August 31. The Earl of Spencer marked the emotional day in a very poignant way on his family's estate in Northamptonshire and shared it with the world via social media.

Charles Spencer pays tribute to late Princess Diana

On Monday August 31, Charles Spencer paid tribute to his late sister Princess Diana at their family home in Althorp, Northamptonshire. He tweeted a picture showing the Spencer family flag at half-mast and captioned it accordingly: "My first family duty on 31 August. Never forgotten."

Althorp House, where the late Princess Diana grew up, has been in her family for over 500 years and housed 19 generations of Spencers. The estate is currently the home of her brother Charles, the 9th Earl of Spencer, and his family. The Spencer family estate is also where she was buried on September 6 in 1997. Charles Spencer, who is a historian, later shared another picture on his Twitter account.

It shows his late sister's memorial where members of the public had placed flowers in remembrance of Princess Diana on the anniversary of her death. "Lovely flowers from all sorts of people today, and recently, at Althorp House: thanks to all of them," Spencer captioned the picture.

Princess Diana died in a horrific car crash in Paris on August 31 1997. She has been gone for 23 years now, but is still considered "The People's Princess". Looking at how her brother Charles always pays tribute to his late sister on the anniversary of her death, she probably never will be forgotten...!
