The BBC have a rather more balanced piece here, which is clearer.
The Post Office are seeking to relocate Acocks Green post office into another local retailer as a franchised office. This would, it can be assumed, then result in the closure of the existing site.
However, they are clear that if a partner cannot be found, then the current post office will be maintained.
There will be a 6 week consultation prior to any move and while people will not be able to object to the principle of the closure/relocation, you will have an opportunity to object to the new location on the grounds of practical issues like parking, etc.
This is slightly more reassuring than the original spin, but will still require close monitoring and might mean another unoccupied store front in Acocks Green, which is never a good thing.
