Former EastEnders actress Gillian Taylforth said she is "shocked and saddened" by the death of her co-star Anna Wing.
Ms Taylforth, who played her character's daughter-in-law Kathy Beale, told Digital Spy: "What a lovely lady Anna was. It was so great to have worked with her.
"She used to say to me all the time that I should never forget her, so I always sent her birthday and Christmas cards every year.
"My thoughts go out to her family as she spoke about them often. She will be sadly missed".
