Dame Barbara Windsor came up with the idea of killing Peggy offBBC

Discussing her soap legacy with The Mirror, Barbara Windsor said: "Peggy is a character close to my heart but I made the decision a while ago that I need to say goodbye to her once and for all. Otherwise she will always be there, urging me to go back. I realised it is time for me and the audience to say our final farewells to the lady I've loved for years."

The 78-year-old actress, who became the queen of the small screen during the 1960s and 70s in the Carry On films, came up with idea of killing off Peggy, as she said that as long as the character was alive, she'd always be drawn back to playing her. "I did my crying afterwards," she said of the last scenes.
