Harry Potter creator J.K. Rowling is turning sports writer to pen a series of match reports from the fictional Quidditch World Cup.

The writer’s fans will be able to read regular updates from the tournament, which first featured in her books about the teenage wizard, on the Pottermore website.

Quidditch – a fictional sport played by the student wizards on flying broomsticks in the bestselling books – is so popular with fans that they have adapted a version of the game that can really be played.

Characters from the books will feature in the reports, which are credited to Harry’s wife Ginny who is billed as “the Daily Prophet’s Quidditch correspondent in the Patagonian desert” where the tournament is said to be staged.

It comes after Rowling posted a history of the tournament last month on the Pottermore site, which includes previously unpublished material about her young hero and also works as a one-stop shop for electronic and digital audio versions of her books.

Her fans are also awaiting her second novel in a crime series written under the pseudonym Robert Galbraith, which is due out on June 19. Galbraith’s true identity was exposed last year after a senior figure at a legal firm which represented her in the past blew her cover.
