The projects being scrapped by the new government are all part of the Building Schools for the Future programme, known as BSF. This was the last government's scheme for getting new school and hospital buildings without paying for them (yet). It was called the Private Finance Initiative (PFI). Basically the PFI is a version of the 'never-never' - private finance (rather than the taxpayer) pays for building a school or hospital, and the Government pays them back over a period of years - and ends up paying much more, of course.
Stockport did not have any BSF projects, which until now many of us thought was a pity - Marple Hall School's buildings being pretty shabby. I believe that those local authorities which are regarded as more 'deprived' than Stockport were first in the queue for BSF funding. So now BSF has bitten the dust, but as far as we're concerned it makes no difference, except that in due course Stockport would probably have been able to get in to the scheme as well, had it survived.
The Rose Hill scheme was nothing to do with BSF, however.
