The team here at the Coronation Street Blog will be bringing you Betty tribute posts in the following few days. Very sad news indeed.
Julie Goodyear who played Bet Lynch, said Driver was "the very foundation of the Rovers Return. It was an honour and a privilege to work with Betty Driver for 25 years. We laughed together, we cried together and never once had a cross word. She was a totally professional actress. A true icon and legend and a very dear friend. She will be missed and remembered by millions."
Barbara Knox, who plays Rita Sullivan in the soap, said: "I have lost a very dear friend and the Street has lost a very great character, a professional to her fingertips - she will be greatly missed."
