BBC News are reporting that the actress passed away peacefully in her sleep on Friday.
Edna Doré (1921 - 2014)
Her agent Belinda Wright told BBC News: “I'd known her for more than 30 years and she was a wonderful actress and great fun.”
Edna’s time on ‘EastEnders’ may have been relatively brief, but she was involved in a number of important storylines before leaving the show in 1990, most famously when her character Mo was diagnosed with Alzheimer’s disease.
As well as her time on the soap, she had a number of other big acting jobs, including the 1988 film ‘High Hopes’, directed by Mike Leigh.
Mike paid tribute to the late actress in the Guardian, fondly recalling: "Edna Doré swore like a trooper, smoked like a chimney, detested bulls*** and didn't suffer fools.
"She was very funny. Her filthy jokes were legendary.
"We will all miss her no-nonsense wit, her generosity, and, above all, her uniquely truthful acting."
Edna and Paul O'Grady in character on 'Eyes Down'
Edna also starred in the BBC dark comedy ‘Eyes Down’ opposite Paul O’Grady, who paid tribute to the actress on his Radio 2 show on Sunday afternoon.
Paul said: “We got sent home from rehearsals one day for laughing. I won't tell you why but Edna said: 'In my 70 years in the business, I've never been sent out of rehearsals'.
"She had a remarkable career. She might be gone but she's not forgotten by me. I had a ball with Edna, what a laugh she was."
She married director and writer Alexander Doré in 1946, and the two were together until his death in 2002. They had one son, Michael, who owns a pub in Sussex.
