Carmel Jackson is a fictional character from the BBC soap opera EastEnders, played by Judith Jacob from 5 June 1986 to 24 August 1989. Carmel, a health visitor, was initially introduced in a recurring, minor role in 1986, when she is credited as "health visitor". Producers saw potential in the character, and script writers were asked to develop more prominent storylines, and Carmel became a regular character. She is portrayed as a well-meaning, caring individual who is forever getting everyone's problems dumped on her. She is featured in storylines about domestic violence and various family and career upsets. Jacob remained in the role until 1989, when she opted to leave. Off-screen, the character was the subject of criticism regarding the portrayal of her profession from the Health Visitors Association.
