The fruit cake, which was perfectly preserved since the wedding reception held at Buckingham Palace in 1947, was auctioned off at Christie's in London.

FUN FACTS ABOUT HRH THE QUEEN'S WEDDING

Originally belonging to one of the royal newlyweds' guards of honour at their Westminster Abbey wedding ceremony, the cake slice was donated to the Princess Alice Hospice in Esher where it lay forgotten in a filing cabinet for 15 years.

After beging discovering during a sort out of the archives, the slice was bought by an antiques dealer on Channel 4's Four Rooms in 2011 before ultimately making its way to London's famous auctionhouse.

Charlotte George, from Christie's, said: "The cake was made using rum and brandy, which would explain how it has lasted so well.

"Remarkably, it is still in one piece, wrapped in baking parchment. I wouldn't recommend eating it - but as a collector's item, it is fantastic."

The lavish four-tier cake originally stood 9ft tall. Prince Philip cut it with his ceremonial sword and divided it between their 2,000 guests. One of the layers was kept aside for the christening of Prince Charles a year later.
