A piece of late Princess Diana’s wedding cake is set to be auctioned, after being found in a former staff member’s attic.

The cake piece which is wrapped up in a metal tin was given to Moyra Smith. Moyra Smith was a former servant of the Queen Mother, who passed away last month.

According to the experts, the piece of cake, could reach a value of £20,000 at auction. It is accompanied by a personal letter from Princess Diana herself.

The Diana memorabilia specialist auctioneer Chris Albury said that this piece is special because it was from the cake sent to the Queen Mother at Clarence House.
