I am so sorry to hear about Geoffrey. He was a warm, lovable actor, with great comedy timing. He will be greatly missed, one of the Street's memorable characters.
Geoffrey Hughes's family said he died on Friday night "peacefully in his sleep" after a "long courageous battle" with prostate cancer.
Hughes, known to millions as playing binman Eddie in Coronation Street during the 1970s and 1980s, was rushed to hospital for intense radiotherapy in 2010 after collapsing at his Isle of Wight home.
The actor had thought he had beaten prostate cancer the previous year, but the star and his wife Sue were given the news the disease had returned.
The Royal Family actor Ricky Tomlinson paid tribute to his friend, Geoffrey Huges. He said:
Geoff wasn't just an actor. He was my mate. I used to call him every few weeks but hadn't spoken to him in about a fortnight. It's such a loss.
A Coronation Street spokesperson added:
We are very sad to hear of the death of Geoffrey Hughes. He created a legendary and iconic character in Eddie Yates who will always be part of Coronation Street. Everyone connected with the programme sends our sincerest condolences to his family and friends.
