This Morning's resident agony aunt Denise Robertson has passed away from pancreatic cancer.
The writer and broadcaster had appeared on the ITV programme since it launched in 1988 and had become a much loved icon.
And speaking to Julia Hartley-Brewer, former This Morning presenter Richard Madeley paid tribute to the 83-year-old.
He said: "She was probably the foremost agony aunt of her generation because she was real. She didn't put it on. She was amazing, absolutely genuine."
Madeley told Julia one of his vivid memories of Robertson was her taking calls and counselling people an hour and a half after the show had gone off the air. This became a regular habit for her.
"You'd go into the phone-in room sometimes four hours after we went off air," he added. "All the people had gone home for the day and Denise would still be in there, on her own time before she got the train back to the north-east, talking to people."
At the end of the interview, Madeley said she'd made a lasting impact.
"She made a difference," he added. "She made a difference to individual lives, a difference that would last a lifetime. And what an accomplishment that is."
