Her most famous TV role was probably as Frank Butcher's battleaxe mother Mo in EastEnders from 1988 to 1990 in a storyline that showed the affects and strains of alzheimers.
For me, she is Phil Davis' mother in the 1988 Mike Leigh film High Hopes, pictured above. It was a role that saw her win the best supporting actress gong at the European Film Awards and she would go on to work with Leigh in the films All or Nothing and Another Year. He has described her in the papers as a woman who "swore like a trooper, smoked like a chimney 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's film career also included roles in Gary Oldman's Nil By Mouth, Goodbye Charlie Bright, Tube Tales, Forty Four Inch Chest and 1998's Les Miserables.
