"Serving The People : The Co-operative Party History from Sam Perry to Gordon Brown" by Greg Rosen, the noted historian of Labour history has been published and is avaiable at the Co-operative Party Conference, price 7.99.
You can read an extract here. The cover appears to feature the legendary tennis player Fred Perry, son of Sam Perry the co-operator. I'm not sure the people of Stockport where Fred Perry was born would have their town described as grim and situated in Lancashire as mentioned in the book. If you want me to bring a copy back from London, let me know.
