Ofsted will start sending teams of inspectors into areas where high numbers of pupils are not getting a good education, in a bid to raise school standards.
In a series of inspections, the watchdog will visit Derby first, as it travels around local authority areas in England over the next few weeks.

It is understood that about 10% of schools in each area will face an inspection.
