A moving letter from the mother of a young cancer sufferer to author JK Rowling has been read out at a performance in London.

The letter states how the young girl, who died this week, had found comfort in the author's Harry Potter series.

Chrissy Hart wrote the letter to the author last month, saying: "Your words built a castle for her to move into when the prognosis got worse."

It was read out by actress Ellie Bamber at a star-studded performance of Letters Live, a series of performances in which remarkable letters are read aloud.

The event is based on the collection of letters published in Shaun Usher's international best-seller Letters Of Note.The 2016 series will run until Tuesday and feature dozens of other famous performers, including Benedict Cumberbatch, Olivia Colman and Carey Mulligan.Letters Live first launched last year and quickly became a sell-out success.
