Eagle-eyed royal fans have spotted an awkward blunder in a post by @KensingtonRoyal on X. The post, which followed Prince William's visit to the permanent memorial in Hyde Park in memory of the 52 people who were killed in the 7/7 attacks on this day in 2005,read: "And copy: Remembering the victims of the 7/7 attacks on this 20 year anniversary by joining survivors and bereaved families at the Memorial Gardens in Hyde Park this afternoon.'

Before it was quickly deleted, fans spotted that "And copy" was a blunder in the post. Taking to X, one fan commented: "And copy?"

Another wrote: "Someone clearly forgot to shave the first two words off in the copy pasting."

A third then wrote: "Someone's getting fired."

Shortly after the first post was deleted, Kensington Palace reposted the message but without "And copy".

The 43-year-old joined survivors of the London bombings and families of the victims for a moving service at the memorial gardens in Hyde Park this afternoon, to mark the 20th anniversary of the tragedy.

On July 7, 2005, four bombs were detonated on three underground train stations and a double-decker bus during London's morning rush hour.

During his solo appearance today, William was one of the last of the 500 guests to take his seat. To match the moving occasion, the royal sported a dark navy suit and tie.

At the end of the service, William was spotted laying a bouquet of bright orange flowers on the plaque.

After the hour-long service, the Prince joined the survivors and the families of the victims for a private reception at a tea tent some 100 yards from the memorial.
