Dame Penelope Keith, a beloved figure in British television, has died at the age of 86. Her family announced her peaceful passing at her home in Surrey, where she had resided for over five decades. The cause of death was cancer, according to a statement released on Monday.

Keith achieved widespread recognition for her portrayal of Margo Leadbetter, the uptight, status-conscious neighbor in the classic sitcom "The Good Life." The series, which aired from 1975 to 1978, explored the unconventional lifestyle of a suburban couple attempting to live self-sufficiently, with Keith's character often serving as a foil to their bohemian ways.

She also captivated audiences as Audrey fforbes-Hamilton, the former lady of the manor, in the equally popular sitcom "To the Manor Born." This role further cemented her status as a comedic talent in the British television landscape.

The family has requested privacy during this difficult time and expressed gratitude for the care and support she received throughout her treatments.
