"This is understandable when we reflect on the many years Tony has been involved in Armthorpe affairs as a Parish Councillor, Ward Councillor, school governor or his involvement with community groups such as the Junior Football Club and Miners Memorial Garden.
“No matter what Tony was involved in he was very much a family man and we hope his family can take some comfort that so many people have expressed their sadness at his passing. He will be missed by many, not least, the family he was so proud of.”
Coun Corden became a councillor in 1992 and served local government on and off right through to present day.
