OP writes 'If 7,000 people have signed a petition against the supermarket where are they all when it comes to turning out to show their support? Or are they all sitting back and thinking somebody else will solve the problem for them?'
No, they're in Hyde, Glossop, New Mills, even Salford and Harpurhey, which according to MIA is where many petition signatories live. The 7,000 isn't all Marple residents, that's for sure!
