The Worst Witch stars: 'It's like you're in a Harry Potter world'

The stars of the new CBBC show The Worst Witch have been telling Newsround about life on the set of the magical drama.

The series follows the story of Mildred Hubble, a girl from a world outside of magic who finds herself landing quite literally head first at Miss Cackle's Academy for Witches.

It's based on the books by famous author Jill Murphy.
