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".
The Worst Witch
In 2004, a new series based on the 1998 series was made, entitled "The New Worst Witch". It centred on the adventures of Mildred's equally bungling cousin, Henrietta "Hettie" Hubble, played by Alice Connor, also set at Cackle's Academy.
