Teachers will be handed tough powers to search pupils for alcohol, drugs and mobile phones in a Government crackdown on bad behaviour.

Rules allowing schools to use physical force to remove unruly students from the classroom are also set to be simplified, while teachers facing accusations from pupils will be granted anonymity to prevent careers being ruined by "malicious" claims.

The raft of measures, which have won support from the teaching profession, were unveiled by Schools Minister Nick Gibb on Wednesday in an effort to restore discipline to the classroom.

Official figures show 2,230 pupils were permanently excluded last year for physical assaults on teachers or fellow pupils and tens of thousands more suspended.

One in five secondary schools is rated "satisfactory" or worse by Ofsted for behaviour and two in five teachers have witnessed physical aggression, a quarter of them being the victims of it.

Mr Gibb said: "Teachers should feel confident in exercising their authority, and pupils should not have to suffer disruption to their learning caused by the poor behaviour of others."
