Disappointed Harry Potter fans booed after an annual announcement at London King’s Cross railway station did not happen.

People gathered at the station hoping to hear an announcement that the fictional Hogwarts Express would depart from platform nine and three-quarters at 11am, as happens in JK Rowling’s books.

The Back to Hogwarts tradition, which celebrates the start of each academic year at Hogwarts School of Witchcraft and Wizardry every September 1, had become an annual ritual for fans of the franchise, as well as visiting the sets, props and costumes at the Warner Bros. Studio Tour in Leavesden near Watford.

Previous years also had a train service being displayed on departure boards, with hundreds of fans attending the 2023 event, but on Sunday London King’s Cross did not mark the occasion.

Media and entertainment company Warner Bros Discovery, which owns the Harry Potter franchise, issued a statement in July urging fans to avoid travelling to King’s Cross on Sunday and instead watch a programme on YouTube hosted by I’m A Celebrity… Get Me Out Of Here! winner Sam Thompson.

It said: “Come 1st September, fans are strongly discouraged from travelling to King's Cross as there will be no event, departure board or countdown at the station.

“Instead, everyone is invited to tune in and join proud Hufflepuff and King of the Jungle, Sam Thompson, in a specially recorded online programme made in celebration of Back to Hogwarts.”
