The request comes after Manchester City Council found itself fielding press enquiries a week before the director of education received his copy of its Ofsted report.
The council's first warning that the report was about to be published came from a press call. Director of education Roy Jobson said he had to resort to getting a copy from a journalist.
'Naming and shaming is all great fun but it only has a point if it leads to improvements,' said LGA head of education David Whitbread. Publishing the report a week early 'doesn't give Manchester an extra week to put things right, but an extra week of hell fielding press calls'.
