Dame Penelope Keith, the celebrated actress renowned for her iconic roles in the 1970s British sitcoms "The Good Life" and "To the Manor Born," has died at the age of 86. Her family announced her peaceful passing on Monday, stating she died at her home in Surrey while living with cancer.

Keith became a household name for her portrayal of Margo Leadbetter, the materialistic and snobbish suburban neighbour in "The Good Life." She later captivated audiences as Audrey fforbes-Hamilton, a widowed aristocrat navigating financial troubles in "To the Manor Born." These roles solidified her status as a beloved figure in British television.

In a statement, her family shared their deep sadness and expressed gratitude for the care and support Dame Penelope received. They requested privacy during their time of mourning. The statement also noted that she died peacefully at her Surrey home, where she had resided for over five decades.

Friends and colleagues have paid heartfelt tributes. Felicity Kendal, who starred alongside Keith in "The Good Life," remembered her as a "comic genius" and a "joy to know and work with." Kendal also extended her condolences to Keith's husband, Rodney, highlighting their "great love story and partnership."

Comedian and presenter Sue Perkins praised Dame Penelope for creating "some of the greatest sitcom characters of all time." Broadcaster Gyles Brandreth described her as "a wonderful actress, a real friend, so funny, so generous with the time she gave to good causes," adding that "Hers was indeed a good life."

Former culture secretary Sir Jeremy Hunt, who was a neighbour and friend, noted that Keith "helped Britain laugh at itself" and brought happiness to millions. Novelist Lissa Evans commented on the contrast between Keith's formidable characters and her real personality, calling her an "utter genius" for making Margo Leadbetter both "adored and oddly vulnerable."

Dame Janet Suzman, who worked with Keith early in their careers at the Royal Shakespeare Company and later on the film "Priest of Love," recalled her as "enormous fun to work with." Suzman highlighted Keith's distinctive "ice pick consonants" and "tremendous self-assurance."

Born in Surrey, Dame Penelope Keith began her acting career with the Royal Shakespeare Company in 1963. Her talent for comedy was recognized with an Olivier Award for best comedy performance in 1976 for her role in the play "Donkey's Years." Her extensive career also included notable performances in theatre and film, leaving a significant legacy in the performing arts.
