Grammar schools 'do not help social mobility'

Grammar schools are "stuffed full" of middle-class children and do not improve social mobility, the chief inspector of schools in England has said.

Sir Michael Wilshaw told The Observer the selective system was not the way to make up ground on other nations.

But Tory MP and former grammar school pupil David Davis told BBC News many working-class children "got on through having access to grammar schools".

The BBC's Alan Soady has more details.
