Bill Tarmey's former colleague Michael Le Vell has described the Jack Duckworth actor as being like a father to him.
Le Vell, who plays the Street's Kevin Webster, said: "Bill met my dad briefly when I first joined Coronation Street. And when my dad passed away Bill became like a surrogate dad to me.
"He and Liz looked after me and got me through those early days and we've been friends every since. My heart goes out to Ali and his family.
"We knew Bill was poorly, but this is still a very great shock. I am going to miss him very much."
