A slice of Prince Charles and Princess Diana's wedding cake is being sold at auction

Chris Albruy - the auctioneer's royal memorabilia expert - said: "It’s a curious and unique keepsake.

"I still wouldn’t recommend eating it but after 40 years it’s clearly destined to last.”

The slice - which measures 8 inch by 7 inches - is decorated with a red, blue and gold royal coat of arms.

It was given to Moyra Smith - one of the Queen Mother's staff at Clarence House - after the ceremony in 1981, and has been preserved in cling film inside a cake tin.

The cake stayed in Moyra's family until 2008 before being acquired by the collector who is now putting it up for sale.

The couple divorced in 1996, and the following year Diana tragically died in a car crash.

Meanwhile, Lady Kitty Spencer - the 30-year-old niece of the late Princess of Wales - married fashion tycoon Michael Lewis, 62, on Saturday (24.07.21) in the Villa Aldobrandini in Frascati, Italy.

Kitty - who is a global ambassador for Dolce & Gabbana - reportedly wore a dress designed by the Italian brand, as did a number of guests, including Viscountess Weymouth, DJ Marjorie Gubelmann and fashion designer Jade Holland Cooper.

Other guests in attendance were Lady Kitty's sisters, twins Eliza and Amelia, the Marquess of Bath; singer Pixie Lott and her model boyfriend Oliver Cheshire; Idris Elba's wife Sabrina; and 'Made In Chelsea' Mark Vandelli.

Lewis, chairman of Foschini Group, and Lady Kitty were first reported to be dating in 2018, while he proposed in December 2019.

The pair are believed to have met through a mutual friend.

Kitty - whose parents are Diana's brother Earl Spencer and model Victoria Lockwood - is believed to be close to Michael's three grown-up children.
