The Worst Witch
Mildred "Millie" Hubble is the protagonist of the series. She is a good-hearted, but bungling young witch-in-training, who never seems to get anything right. She is friends with Maud Spellbody and Enid Nightshade and has a strong rivalry with Ethel Hallow. It is Miss Hardbroom, her potions teacher, who calls her "The Worst Witch".
Kate Duchêne
She briefly went to Spain, teaching English to children, and returned in 1986.
Duchêne is best known for her work as Miss Constance Hardbroom, the strict "deputy head and potions teacher" on the popular TV series "The Worst Witch". She stayed with the programme for its three-year run, and appeared in the first episode of its 2001 spinoff "Weirdsister College" but did not return for the second spinoff, "The New Worst Witch" (2005–2006). Later projects included "Afterlife", a paranormal drama series, and extensive theatre work.
