Pupils will be banned from having mobile phones in their pockets or in their bags while at school in England as the government brings in new, stronger rules.

Statutory guidance that came into force in June means that schools are already required to be phone free, but does not explicitly set out how teachers should enforce this.

But new, tougher guidance means the "no see no hear" policies used by some schools will not go longer go far enough as teachers will be asked to make sure phones are inaccessible to children while they are at school.
