Are Britain's children being let down by bad teachers? The latest research from the government's education inspectorate, Ofsted, suggests that some teachers may not be up to their jobs.

Tonight's Panorama investigates both issues and visits three schools in the front line of the new "class struggle".

(Note: because Panorama is a topical programme and likely to react to events in the news, the above programme is liable to change.)
