This is the situation as I understand at the moment:
Inspector Morrissey stated that the station in Marple wouldn't close in the immediate future (however long that is noone knows!! ).
She (at least I think she) also said that even if the police station was to close, it would only be after the police officers for Marple have been relocated to another place within Marple. She did state that even if the station was to close there would continue to be a police prescence in Marple.
There is a sign on the enquiry desk at the station saying that it is due to close shortly, but that only applys to the enquiry desk, not the whole station. Inspector Morrisey claims that the Enquiry Desk is outside her remit.
The District Centre Partnership has been promised to be kept informed any any further developments.
To be absolutley sure of things I would contact either Patrick (Chair, Marple District Centre Partnership) or Brian (SMBC Regeneration Officer for Marple),
